29012100 UNSATURATED ETHYLENE

Ethylene is a colorless flammable gas at normal pressure and temperature with lively properties. Its boiling point is -103.71°C, critical temperature is 9.90°C, critical pressure is 4.95MPa, and critical density is 0.227kg/L.

Ethylene is one of the most basic raw materials of petrochemical industry. In terms of synthetic materials, ethylene is widely used in the production of polyethylene, vinyl chloride, polyvinyl chloride, ethylbenzene, etc. In terms of organic synthesis, it is widely used in the synthesis of ethanol, acetic acid, propionic acid and its derivatives and other basic organic synthesis raw materials .

Ethylene is also an important basic raw material for organic chemicals, mainly used in the production of polyethylene, ethylene-propylene rubber, and polyvinyl chloride.

Process

The industrially used ethylene production methods include petroleum hydrocarbon cracking, ethanol catalytic dehydration, coke oven gas separation, etc. Due to the abundance of oil and natural gas resources, large-scale production of ethylene has low cost and good quality. Therefore, a large amount of ethylene is mainly produced by petroleum cracking.

Application

①One of the most basic raw materials for petrochemical industry, it is mainly used as the standard gas for analytical instruments in petrochemical enterprises, as the environmental ripening gas for navel oranges, oranges, bananas and other fruits, and as the synthesis of medicine and high-tech materials.
