How to test alcohol for methyl alcohol. Differences Between Methyl and Ethyl Alcohols

Hello dear readers! The current traditions are very different from the past. Today, young people immediately propose to a girl without talking to their parents before that. But situations are different and traditions in certain families sometimes require a similar act from the future groom. Therefore, today I would like to talk with you about how to ask for the hand of a girl from her parents.

To do everything right, first talk to your lover. Find out how her father proposed to her mother, what rules and traditions they follow. Indeed, now not everyone adheres to the old customs, and for some parents this may come as a complete surprise, while others will react quite normally to such a step on your part.

This is especially important if your favorite foreigner. Indeed, in her culture, such a step can be accompanied by certain actions. Do a little research on its culture and traditions to be ready to make the right marriage proposal.

After all, a wedding requires serious investments: rings, holding a wedding, a banquet, a honeymoon, and so on. If you are ready and decided, then you cannot do without my articles "" and "".

Preparing for a conversation

Not every guy is easy to immediately find an approach to his father or mother. Therefore, just a meeting is so important, where you can get to know each other better and understand how her mom and dad will react to the proposal.

After all, they may be categorically against it. And here everything will depend on your chosen one. If she obeys her parents in everything, then she can refuse. If she is used to deciding for herself, then the answer of her parents will not greatly affect her choice.

Of course, it is better to prepare in advance for such a serious conversation with parents. Choose the right place and day. Perhaps your future mother-in-law has a birthday soon? Then you can use it. Just be sure to think in advance what you will say.

What if her parents live far away? It's OK. Just invite your beloved to visit them in the near future. Such an act on your part will be well received. In addition, it will show the seriousness of your intentions.

Important day

If you are very nervous and worried, then it is better to record your speech and rehearse it with a friend, for example. This will make you feel more and more courageous. Do not forget that parents can start asking questions and you need to be ready for this too. Let a friend ask you a couple of tricky questions, and you think over the answers to them.

Best wishes to you!

So, do you want to get married? Excellent! This is a big and important step in the life of any person and should be taken seriously. In this article, you will learn how to ask the parents for the hand and heart of the bride. Keep in mind that each family has its own rules and regulations, so everything needs to be carefully weighed in this matter. Think about whether your girlfriend's feelings will be hurt if you first ask her parents for her hand in marriage. Remember that with your beloved you will live the rest of your life, which means that the issue of a marriage proposal must be taken seriously.

Steps

Think it over. Is it the right time to get married? Are there reasons against your marriage? Think about the reaction of the girl's parents. If you know each other for only a couple of weeks, maybe it makes sense to wait with the wedding and get to know each other better?

Choose a location. You should choose the perfect time and place. Most often, such topics are discussed in the parent's house at the dinner table, or you can invite your girlfriend's parents to a cafe. Think about whether you should ask for blessings yourself or should your girlfriend be there?

Know what you are going to say! This will help reduce nervousness. Talk to yourself, develop a conversation plan. After a short opening speech, your question will have more success.

Look good. What parent wants their daughter to marry a slut? Take a shower, put on clean and ironed clothes. Even clean jeans and a shirt look great. Also, take care of your breathing.

Be polite. Most likely, when you make an appointment, they will understand what is at stake. They will already have a hint as to what you are going to do. Therefore, be polite and straightforward.

Explain how much you love their daughter and how she has changed your life. Then take a deep breath and ask, "I would like to ask for your blessing to marry your daughter." They may be completely shocked, or they may be ready for your offer and nod their heads in approval. Tell them that you understand that this is a big step and that you are willing to wait for their response if they need to think. It may take some time for the parents to decide, so leave them alone by saying, “I'd better go so you can think things through! Let me know when you make a decision. I will look forward to it." You may have to wait for a few days. Do not show the ring! It is considered bad luck to show the ring. Do not rush, let everything take its course, and very soon you will enjoy the most important event in your life together. life.

• Prepare yourself for "No". Ideally, you will hear "Yes", but there is always the possibility of being misunderstood by parents. Remember, your girlfriend's parents are people with their own opinions, fears and dreams, just like you. If they really don't want you to marry their daughter, ask them why. If their arguments seem wrong to you, you can gently try to calm them down and make reasonable arguments in your favor. Perhaps they will change their mind. If they don't, then you'll have to choose between marrying anyway or leaving the girl alone.
• Remember if your girlfriend loves you. She will at least ask her parents to be polite. If she allows them to be rude, then this is a clear sign to reconsider her offer.
• Remember to take into account all the norms of behavior adopted in the country and culture of your bride. Perhaps the bride's parents are much more conservative than she is. Therefore, you need to be prepared. In some traditions, the groom's address to the bride's parents can be perceived as disrespectful to the choice of the daughter. Others believe that the groom's appeal to his parents is a manifestation of respect and good breeding. Therefore, this is a rather controversial issue.

Warnings

• Do not show the ring - it can bring bad luck.

• Don't talk about how rich you are! Even if your income is high enough, you should not advertise it. Instead, you can say, “I can take care of your daughter financially. She will always have what she needs."

One of the most terrible alcohol poisoning is the use of methyl (technical) alcohol instead of ethyl (food) or medical. Even a small dose can be fatal. I will tell you how to distinguish methyl alcohol from ethyl alcohol. After the events in the Czech Republic, where thousands of people suffered from fake alcohol containing methanol, this information became vital.

The problem is that technical alcohol does not differ in taste, smell and color from food alcohol. It is this feature that causes poisoning. Usually methanol is found in solvents, antifreeze liquids and other household chemicals that are not intended for ingestion, but due to various circumstances it can be sold under the guise of drinking.

Methods for determining technical alcohol

1. Origin. Buy alcohol in trusted stores, where the risk of becoming a victim of a fake is much lower than at dubious points of sale (stalls, moonshiners, etc.).

Drink and dilute pure alcohol only from well-known sources. If it is the products of distilleries or medical alcohol, there will be no problems, in all other cases the risk of accidentally drinking methanol increases many times over.

2. Ignition. This is one of the easiest ways to check. The liquid is set on fire and the color of the fire is monitored. Ethanol burns with a blue flame, technical alcohol with a green one.

3. Potato check. A small slice of raw potatoes is thrown into a container with alcohol for several hours. If the potato has not changed its color, then you have pure food alcohol that you can drink. In methanol, potatoes usually take on a pink hue.

4. Formaldehyde test. It is considered one of the most reliable methods. Copper wire is heated on fire, then immersed in a liquid. If there is a sharp unpleasant odor, you can not drink alcohol, it is methanol. Ordinary ethanol, when immersed in hot copper wire, does not emit odor.

Symptoms of technical alcohol poisoning:

• severe headache;
• labored breathing;
• general malaise;
• pain in the abdomen and lower back;
• vomit;
• lethargy.

All these signs are also similar to ordinary alcohol poisoning, so they are often confused. But in the case of methyl poisoning, the consequences are much more serious. Methanol quickly destroys the visual, nervous and vascular systems. For severe poisoning, 5-10 ml of methanol is enough, and 30 ml causes death.

If a person becomes ill after drinking alcohol, doctors recommend immediately calling an ambulance, and not hoping that everything will go away by itself.

Ethyl alcohol can be consumed. Methyl is used only for industrial purposes, for the production of solvents. Both species have the same smell and transparency. It is impossible to visually distinguish methyl alcohol from ethyl alcohol. In laboratory studies, this can be verified without much difficulty.

It is important not to make a mistake and choose the right product. Technical fluid, even in small quantities, can cause various violations. First of all, the central nervous system and organs of vision are affected. A person develops a deterioration in health, weakness, pale skin, back pain, dizziness, and blindness.

How to check ethyl or methyl alcohol

Both drinks have exactly the same color, completely transparent. You can never tell one from the other by appearance. When ignited, the compounds ignite equally quickly, there is no difference in this. They burn with a bluish tint.

Indirectly, the presence of a low-quality product can be assumed to smell.

When opening two containers together, you can feel the characteristic vodka smell. His absence should alert and make you think about the consequences.

If there are doubts about the quality, do not take risks and use such products. It is difficult to distinguish these drinks from each other on your own.

Home methods for determining

You can distinguish alcohols with the help of improvised means. It must be remembered that these methods carried out at home cannot fully replace laboratory studies. There are several ways in which these liquids can be distinguished:

• The color of the flame when ignited;
• Interaction with raw potatoes;
• A characteristic reaction with potassium permanganate;
• Boiling temperature;
• Experience with soda;
• Formaldehyde;
• Lang test.

It is not recommended to be content with any one sample, this will not help to distinguish them. Before the possible use of alcohol, it is necessary to conduct several experiments to distinguish them from each other. This will most reliably determine the nature of the liquid. It is worth remembering that none of the home methods will give 100% certainty. The abuse of alcohol-containing products leads to the development of physical and mental dependence.

flame color

It is necessary to pour a small amount of liquid into an iron spoon and bring a lit match or lighter to it. Ethanol has a blue flame. The technical one burns with a bright green flame. This is because ethyl contains a large amount of hydrogen. One molecule contains 6 atoms. When in contact with oxygen, carbon is formed, which gives the flame a blue-blue color.

One of the possible ways to distinguish alcohols is ignition.

The methanol molecule contains only 4 hydrogen atoms. Therefore, when reacting with oxygen, it glows green. This method cannot be completely trusted. Various additives to alcohol can give the flame a bluish tint.

Reaction with potatoes

Simple folk methods include a test with potatoes. It is necessary to peel raw potatoes, put a small piece in containers with alcohols. If the color of the potato has changed to pink, then this is technical alcohol. It cannot be used. In ethanol, the color of the vegetable will remain the same.

Reaction with potassium permanganate

Another option to distinguish one liquid from another is the use of potassium permanganate. I need to take two glasses. Pour in the test liquids. Add a few drops of manganese. If the alcohol began to boil, bubbles began to appear, then this is dangerous methyl alcohol. This is because when manganese ions and methanol ions combine, carbon dioxide is released.

If you conduct such an experiment with ethanol, then there will be no bubbles. Carbon dioxide is not released. This is their difference.

This method should not be completely trusted. Sometimes mixing of both alcohols is possible. Then there may be no streak. But this does not mean that this product is ready for use. Even diluted methanol can cause negative effects in humans. All persons suffering from alcoholism are at risk.

Boiling temperature

Alcohols have different chemical compositions and different boiling points. Sample description:

1. The liquid must be poured into a ladle and heated.
2. Prepare an industrial thermometer.
3. Determine at what temperature boiling occurs.
4. Methanol will boil at 60 degrees. Ethanol - later, at 80 degrees.

Alcohols differ in density, therefore, the evaporation temperature of methyl alcohol will be lower. The most dangerous volatile compounds begin to evaporate first.

Reaction with baking soda

You need to take two containers. Throw in some baking soda. Then drip with an alcoholic solution of iodine. They differ in that ethanol precipitate is formed. Technical remains transparent. This is easily explained by the fact that the reactions occur in an alkaline environment. When ethanol and iodine molecules combine, a special substance is formed - iodoform. It sinks to the bottom.

Formaldehyde test

According to the instructions, this study should be carried out as follows:

1. Pour spirits into two different glasses;
2. Thoroughly heat a piece of copper wire;
3. Alternately lower it into these glasses;
4. After a few seconds, she is sniffed;
5. If the smell of formaldehyde is strong, it is dangerous methanol. In ethanol, the smell will not change.

When copper and methanol are heated, oxidative reactions occur. Formaldehyde is released, which has the smell of rotten apples.

Lang test

To carry it out, take 500 ml of distilled water and 1 g of potassium permanganate. Shake well. In order for the crystals of potassium permanganate to disperse well. Then take 50 ml of this solution and add water to 500 ml. Then pour the test liquids.

Add a few drops of the prepared composition with a syringe or pipette. Methyl alcohol will discolor immediately. Ethyl - much later, after 20-25 minutes. This is because methanol contains much more fusel oils, which neutralize potassium permanganate. This is how they differ from each other.

Precautionary measures

Methyl alcohol is used to produce formaldehyde. This is a dangerous volatile compound. It is dangerous not only to use, but also to inhale methanol vapors.

It must be remembered that no home methods can reliably distinguish a dangerous product from a safe one.

Cases of methyl alcohol poisoning happen with enviable regularity. Alcoholism, drinking bouts force a person to use more and more low-quality products. The use of methanol can cause inhibition of all vital systems of the human body. Loss of vision, kidney and liver failure develop.

Even the timely provision of medical care does not always have the desired effect. The patient develops various complications, up to death.

The effect of methyl alcohol on the body. Ways to distinguish between methyl and ethyl alcohol.

Many people have mixed feelings about alcohol. Some people regularly drink alcohol, while others cannot stand it. There are many alternative options for alcohol. Now on the shelves of stores there are a lot of various tinctures based on hawthorn, mountain ash and medicinal herbs.

Ignorant people may think that you can use any alcohol. But actually this is wrong. After all, not all types of alcohol are alcohol, there are a lot of poisons among alcohols. Do not take methyl alcohol, as it is poisonous.

It is difficult to distinguish between ethyl and methyl alcohol by taste and smell. They are almost indistinguishable and you will not even guess that you are drinking a fake. The taste and smell are similar to those of ethyl alcohol. Alcohol was produced by synthesis from hydrogen, but now this method is considered artisanal and is not used. The cheapest can be considered production from waste oil products.

Methanol is mainly used in the chemical industry. It is an auxiliary substance for obtaining many solvents.

Scope of methyl alcohol:

• For the manufacture of solvents
• In the paint industry
• In the production of biodiesel from oils
• To combat hydrates in the gas industry

The fact is that 30-100 ml of methyl alcohol can lead to convulsions and even death. Accordingly, it is impossible to make a mistake, since this is fraught with disastrous consequences. The taste and smell of alcohols are the same. A non-tasting expert will not be able to tell the difference between these liquids.

Ways to check alcohol:

• Ignite. Pour some liquid into the spoon and set it on fire. Ethyl alcohol will burn with a blue flame, and methyl alcohol with green.
• Potato test. Peel potatoes and cut into pieces. Dip one slice in ethanol and the other in methanol. If the slice turned pink, you have poison in front of you, that is, methyl alcohol. In alcohol, potatoes practically do not change color.
• Copper wire. Heat a piece of copper wire to black and dip it into the liquid. If you smell vinegar, then the alcohol is ethyl alcohol and you can drink it. If the smell is unpleasant, then methyl alcohol.

Below are the formulas for alcohols:

CH3OH - methyl alcohol

C2H5OH - ethyl alcohol

How to check ethyl or methyl alcohol in alcohol - vodka or moonshine, at home?

There are several ways to spot a fake:

• Baking soda. Pour some baking soda into the liquid and observe the reaction. If there are impurities of methyl alcohol, the soda will dissolve completely. If the product is of good quality, then a yellow precipitate forms and you can drink alcohol.
• Potassium permanganate. Pour potassium permanganate into a container with liquid. If bubbles appear on the surface, then methyl alcohol. If not, then ethyl.
• Boiling. This can be found with a thermometer, the boiling point of ethanol is 78 ° C, and methanol 64 ° C.

This method is also used to identify alcohol. Ethanol burns with a blue flame, while harmful methanol burns with green.

This indicator reacts to changes in acidity. The most interesting thing is that methyl orange is made on the basis of methyl alcohol. Therefore, when the indicator is introduced into methanol, nothing will change. The solution will be orange. Ethanol has an approximately neutral environment, so the color will not change significantly. The solution will be orange. Thus, with the help of an indicator, these alcohols cannot be distinguished.

Methyl alcohol is a very strong poison, it has a nerve-paralytic effect. Approximately 30-100 ml of methanol causes severe poisoning and convulsions.

Symptoms of poisoning:

• Dizziness
• Drowsiness
• Salivation
• Impaired coordination of movements

To lose sight it is enough to drink 10 ml, and to die 30-100 ml.

If you doubt the quality of alcohol, then do not drink it. But if you still can't resist, watch your condition.

Manifestation of poisoning:

• Flies before the eyes
• Pressure surges
• Vomit
• Nausea
• copious saliva

In general, methanol accumulates in the body, so the symptoms of poisoning may not appear immediately. On average, the effect of methanol manifests itself from 30 minutes to 3 days. And the saddest thing is that on the third day it does not get better, but worse. You may notice loss of vision and infrequent urination. This means that the kidneys are not working properly.

First emergency aid for poisoning with methyl alcohol, methanol

Urgent care:

• Lay the patient on his stomach if he is unconscious. This will help prevent suffocation.
• Give plenty of baking soda solution
• Induce the patient to vomit
• Give the patient a laxative
• Call an ambulance

The most interesting thing is that the antidote is pure alcohol or good vodka. It is necessary every 3 hours for 50 g of vodka.

In fact, the consequences of poisoning are very sad. This can lead to death or blindness.

Effects:

• vision loss
• kidney failure
• Dyspnea
• convulsions
• Epilepsy
• cirrhosis

Variants of poisoning by inhalation of vapors:

• Poisoning can occur due to contact with the skin when wiping the windshield. To prevent this from happening, you need to pour it into the car in a well-ventilated area, using gloves.
• You can get poisoned with methanol in the chemical industry. Also methanol is a part of some paints, varnishes and solvents. Poisoning can occur if safety rules are not followed.
• And when painting or caring for a car (using chemicals), you must definitely follow the safety rules.

Methyl alcohol tastes and smells not much different from ethyl alcohol, so be careful and do not drink questionable alcoholic beverages.
