1、 Overview
The scientific name is ethanol, and the molecular formula is CH3 CH2 oh
Chemical properties: colorless, transparent, flammable and volatile liquid. It has the smell of wine and pungent spicy taste. Soluble in water, methanol, ether and chloroform. It can dissolve many organic chemicals and some inorganic chemicals. It has hygroscopicity and can form azeotropic mixture with. Ethanol vapor is mixed with air to form an explosive mixture, with an explosion limit of 3.5-18.0% (volume).

3、 Purpose:
Ethanol is one of the important basic chemical raw materials. There are more than 200 kinds of chemical products with ethanol as raw material. It is widely used in the production of basic organic raw materials (such as chloroethanol, acetaldehyde and acetic acid), pesticides (such as various organophosphorus pesticides and pesticides), and organic chemical products such as medicine, rubber, plastics, man-made fiber and detergent. Ethanol is an important organic solvent, which is widely used in industrial production such as paint, dye, medicine, grease and military industry.
