Ethanol is a kind of organic substance, commonly known as alcohol. Its structure is simple CHram CHram OH, Cram Hram OH or EtOH. The molecular formula Cram Hram O is a saturated monool with one hydroxyl group. It is a flammable and volatile colorless transparent liquid under normal temperature and pressure. Its aqueous solution has the aroma of wine and slightly stimulating. It has the smell of wine and the pungent taste of stimulation, slightly sweet.

The density of ethanol liquid is 0.789g/cm_ (20 C), the density of ethanol gas is 1.59kg/m_, the boiling point is 78.3 C, the melting point is - 114.1 C, and it is flammable. Its vapor can form an explosive mixture with air, and can dissolve with water in any ratio. It can be miscible with chloroform, ether, methanol, acetone and most other organic solvents with relative density (d15.56) of 0.816. Ethanol is widely used in the manufacture of acetic acid, beverages, flavors, dyes and fuels. Ethanol with a volume fraction of 70%-75% is also commonly used as disinfectant in medical treatment. It is widely used in national defense industry, medical and health care, organic synthesis, food industry, industrial and agricultural production. Ethanol and methyl ether are isomers.

According to the product series (BG384-81), it can be divided into excellent grade, first grade, second grade, third grade and fourth grade. The first and second grades are equivalent to high purity alcohol and ordinary distillation alcohol. The third level is equivalent to medical alcohol and the fourth level is equivalent to industrial alcohol. The new secondary standard is designed to meet the needs of different users and production, reduce waste in production and use, and promote the improvement of product quality.

Disposal in accordance with the requirements of relevant national and local laws and regulations. Or contact the manufacturer or manufacturer to determine the disposal method. According to the Regulations on Safety Management of Hazardous Chemicals, this product is controlled by the public security department because of its explosion-prone nature, and low-concentration medical ethanol is not controlled.
