Application areas

Ethanol is an important organic solvent, which is widely used in medicine, coatings, sanitary products, cosmetics, oils and other aspects, accounting for about 50% of the total consumption of ethanol.

Ethanol is an important basic chemical raw material, used in the manufacture of acetaldehyde, ethylene, ethylamine, ethyl acetate, acetic acid, ethyl chloride, etc., and derived from medicine, dyes, coatings, spices, synthetic rubber, detergents, pesticides and other products Many intermediates, its products up to more than 300 kinds, the use of ethanol as an intermediate of chemical products is gradually declining, many products such as acetaldehyde and acetic acid no longer use ethanol as a raw material and are replaced by other raw materials.

75% ethanol aqueous solution has strong bactericidal ability, is commonly used disinfectant. Specially refined ethanol can also be used to make beverages. Similar to methanol, ethanol can be used as an energy source. Some countries have begun to use ethanol alone as automobile fuel or blended with gasoline (more than 10%) to save gasoline.

Packaging, transportation and safety

Precautions for storage: Store in a cool and ventilated warehouse. Keep away from fire and heat source. The temperature of the warehouse should not exceed 30 ℃. Keep container sealed. It should be stored separately from oxidants, acids, alkali metals, amines, etc., and avoid mixed storage. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
