Ethanol is the main component of alcoholic beverages. Regular vodka costs 40% of it. In everyday life it is called alcohol. Although in reality this term describes a huge class of organic substances. The boiling point of alcohol at normal pressure is 78.3 degrees Celsius. This only applies to undiluted ethanol. The boiling point of the alcohol solution is usually somewhat lower. In this article we will understand what ethanol is. We will also discuss its physical and chemical properties, features of production and use. We will not bypass the side and the main question regarding what the boiling point of alcohol.
Ethanol is one of the most famous alcohols. The composition of its molecules include elements such as carbon, hydrogen and oxygen. Chemical formula of ethanol - C2 H6 A. It is a colorless liquid with a specific alcoholic odor. It is lighter than water. The boiling point of alcohol is 78.39 degrees Celsius. But it is at normal pressure. The boiling point of rectified alcohol is 78.15 degrees Celsius. It contains 4.43% water. The boiling point of ethyl alcohol is the less, the more dilute it is.
Application in life and industry
Ethyl alcohol is an excellent solvent. It is produced by the method of fermentation of sugar by yeast. In many villages of the post-Soviet countries, it is still being made at home. The resulting alcoholic drink is called moonshine. Ethyl alcohol is the oldest recreational drug used by man. It can cause alcohol intoxication when consumed in significant amounts.
Alcohol boiling point of pressure
When reference books indicate the physical properties of substances, it is necessary to understand that all these measurements were made in the so-called normal conditions. With increasing pressure, the boiling point of ethyl alcohol decreases. Today you can find a lot of tables that provide reference data on this issue. At 780 mm Hg ethanol boils at 78.91 degrees Celsius, at 770 - 78.53ºC, at 760 - 78.15ºC, at 750 - 77.77ºC, at 740 - 77.39ºC, at 720 - 76.63ºC .
Boiling point methyl alcohol
CH3 OH is initially produced as a by-product of the destructive distillation of wood. Today it is produced directly from carbon dioxide and hydrogen. The smell of it is very similar to ethanol. However, methanol is very toxic and can lead to death. The boiling point of alcohol is 64.7 degrees Celsius. It is used as an antifreeze and solvent. It is also used for the production of biodiesel.
Fermentation of sugar to produce ethanol is one of the earliest biotechnologies in the service of humanity. The intoxicating effect of drinks based on it has been known for a long time. People always liked the state of altered consciousness that it causes. Even 9000 years ago, the Chinese knew alcoholic beverages. Distillation, as a process, was well known to the Arabs and Greeks, but they had enough wine. Alchemists learned to produce alcohol from it only in the 12th century. Synthetically, ethanol was first manufactured only in 1825 by Michael Faraday.
Chemistry and Medicine
Ethanol is mainly used as a raw material for the production of other substances and solvent. It is one of the components of many household products that are consumed daily in everyday life. Ethanol is included in the wipers and antifreezes. In medicine, it is used as the simplest antiseptic. He well disinfects and dries wounds. It is also used for the manufacture of all kinds of tinctures and extracts. In addition, it cools well and warms. In the absence of other drugs, it was used as anesthesia.
Society and culture
In a study published in 2002, it was found that 41% of deaths in car accidents are due to drunk driving. The higher the blood alcohol content of the driver, the greater the risk. Drinking alcohol has a long history. This social phenomenon is devoted to a lot of research. The process of drinking alcohol and intoxication is described in many works of art. The famous New Year's film “Irony of Fate, or Enjoy Your Bath!” Is dedicated to the consequences of alcohol abuse, albeit in a comedic form. Many creative people have used alcohol as a necessary element of generating new ideas or an easy way to overcome stress. Moderate alcohol consumption is acceptable and even desirable in most modern cultures. Drinking alcoholic beverages is a tradition at many celebrations. The exception is Islam. According to the rules of this religion, the use of any alcoholic beverages is a terrible sin.
Alcoholism and its consequences
Excessive drinking is a disease. It is characterized by physical and mental dependence on vodka or other strong drinks, is a kind of substance abuse. Alcoholics lose control over the amount drunk. They need an increasing dose of pleasure. It is believed that the improvement of the welfare of the population leads only to an increase in the consumption of alcoholic beverages. For the first time the study of chronic alcoholism took Swedish doctor M. Guss in 1849. He identified a number of pathological changes that occur in humans with the systematic use of alcohol. Now scientists are drawing a clear line between alcoholism and drunkenness. The second is a disease that a person cannot cope with. It goes through several stages in its development. At each new stage, the dependence gradually increases. The patient needs a larger dose. Gradually chronic alcohol intoxication leads to somatic disorders. The initial signs of physical and mental dependence include the loss of control over the use and the appearance of heavy drinking. Persons with severe alcoholism are distinguished by failures in the work of internal organs and mental disorders.
Treatment and Prevention
To combat alcohol addiction requires medication. First, medications are needed to eliminate the body's malfunction. Secondly, medications that are not compatible with the use of alcohol are required. It is communicated to the patient that hard drinking during treatment can lead to his death. In addition, psychologists must work with patients. Their task is to consolidate the effect of treatment and form a negative view of drunkenness. Also compulsory is the social rehabilitation of former alcoholics. It is important to help a person find his place in society, return the family. Happy people do not go to the bout. Therefore, the treatment of alcoholism is more dependent on the skills of the psychologist.
