Absolute Ethanol is a colorless clear liquid with a special fragrance and easy to flow.
It is easy to absorb moisture from the air, and can be miscible with water and various organic solvents such as chloroform and ether in any ratio. Its purity can reach to 99.9%,and it can form an azeotropic mixture with water (4.43% water), with an azeotropic point of 78.15 ℃. The relative density (d204) is 0.789. Melting point is -114.1 ℃. Boiling point is 78.5 ℃. Refractive index (n20D) 1.361. Flash point when closed (the temperature at which a combustible gas is heated and volatilized in a container with a specified structure and mixed with the air near the liquid surface to reach a certain concentration and can be ignited by Mars.) combustible. The mixture of steam and air can form an explosive mixture with an explosion limit of 3.5% to 18.0% (volume). The organic solvent is extremely versatile, mainly used in medical, cosmetics, hygiene products, oils and dyes.
Ethanol is an important organic solvent, widely used in medicine, paint, hygiene products, cosmetics, oils and other aspects, accounting for about 50% of the total ethanol consumption. Ethanol is an important basic chemical raw material. 75% ethanol aqueous solution has strong sterilization ability and is a commonly used disinfectant. Specially refined ethanol can also be used to make beverages.
