In the old days, alcohol production is considered as an art and special scientific skill. Until the well-known French chemist and scientist, gay-lussac, showed that glucose was the main source of fermentation of ethanol, and eventually the role of yeast was proven in the process of immersion in 1837, after which Louis Pasteur discovered the anaerobic property of the yeast And the process of alcohol production entered its industrial stage.

Ethanol is a volatile, volatile liquid that is mixed with water in every respect and naturally has a distinct smell. Its freezing point is 127 ° C and its boiling point is 78.3 ° C. In industry, a wide range of ethanol is used as a solvent for a variety of varnishes, polishes, perfumes as an environment for chemical reactions and crystallization. In addition, ethanol is an important primary ingredient in synthesis. Ethanol is used in the formulation of some colors, varnishes, and in the preparation of saltines, glosses and polishes. Ethanol is used in an antifreeze industry due to the low melting point. A solution of 70 to 85% is used as an antiseptic solution. Ethanol eliminates the microorganisms by changing the protein and dissolving the fat. Of course, it only works against bacteria, viruses and fungi, but it does not affect the spores. Ethyl alcohol in recent years, as a renewable source of products (agricultural products), biodegradable, compatible with most natural and artificial household and industrial materials (eg plastics, textiles, etc.). .), Has no skin and respiratory allergenic effects for humans (unlike most of the chemicals used at home and at work), and in many countries, especially advanced industrial countries, have been particularly well regarded and Certainly, it will soon find its true place in various medical, industrial, home and personal uses in Iran. Ethanol has a variety of applications in the pharmaceutical, rubber, paint, solvent and vehicle fuel applications. Unlike oil, ethanol is considered to be a renewable material, which does not cause environmental problems or contamination.

Ethyl alcohol in the Iranian market is mainly of ethyl alcohol type (with a degree of purity of at least 96% and impurities below the limits specified in the standards) and industrial ethyl alcohol (with a volumetric purity of 90% and containing non-purity of non- Allowed in alcoholic alcohol, which is offered for easy diagnosis of alcohol alcohol by adding color and turbinate inside the bottle). Alcohol in addition to medical and antiseptic medicine is also used in the pharmaceutical, food, and cosmetic industries. Industrial alcohol should be used solely for industrial use (solvent, lipid cleanser, primary substance) or as a fuel, and its use in health, domestic and personal use is not permitted.
