Anhydrous ethanol

Colorless clear liquid. It has a special fragrance. Easy to flow. It is easy to absorb water from the air and can be mixed with water, chloroform, ether and other organic solvents in any proportion. Can form azeotrope with water (4.43% water), azeotropic temperature 78.15 ℃. Relative density (d204)0.789. Melting point - 114.1 ℃. Boiling point 78.5 ℃. Refractive index (n20D)1.361. Closed cup flash point (heating volatilization in the regulation of the structure of the container near the combustible gas and the liquid surface air mixing, reaches a certain concentration could be ignited by Mars temperature) 13 ℃. Flammable. Vapor mixed with air can form explosive mixture, explosion limit 3.5% ~ 18.0%(volume). The organic solvent is widely used in medical treatment, cosmetics, sanitary products, oils and dyes.

Functions and USES

Ethanol is an important organic solvent, widely used in medicine, paint, hygiene supplies, cosmetics, oil and other aspects, accounting for about 50% of the total ethanol consumption. Ethanol is an important basic chemical raw materials, used in the manufacture of acetaldehyde and ethyl diene, ethylamine, ethyl acetate, acetic acid, ethyl chloride, etc., and derived the medicine, dye, coating, spices, synthetic rubber, detergent, pesticide and so on many of the intermediate products, the products up to more than 300, ethanol intermediate in chemical products use is decreasing gradually, many products such as acetaldehyde, acetic acid, ethyl alcohol is no longer using ethanol as raw materials and other raw materials instead. 75% ethanol aqueous solution has strong bactericidal ability and is a common disinfectant. Specially refined ethanol can also be used to make drinks. Like methanol, ethanol can be used as an energy source. Some  has begun using ethanol as fuel alone or mixed into gasoline (10%) used to save petrol.
