How is industrial ethylene produced and what is its use?

Industrial method, industrial ethylene is mainly separated from the gas produced by refineries and petrochemical plants.

Main uses:

1. Ethylene is an important basic raw material for organic chemical industry, which is mainly used to produce polyethylene, ethylene-propylene rubber and polyvinyl chloride.

2. One of the most basic raw materials in petrochemical industry. In terms of synthetic materials, it is widely used to produce polyethylene, vinyl chloride and polyvinyl chloride, ethylbenzene, styrene, polystyrene and ethylene-propylene rubber. In organic synthesis, it is widely used to synthesize ethanol, ethylene oxide, ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid and their derivatives. Vinyl chloride, chloroethane and bromoethane can be produced by halogenation; α -olefins can be prepared by oligomerization, and then higher alcohols and alkylbenzenes can be produced.

3. It is mainly used as standard gas for analytical instruments in petrochemical enterprises;

4. Ethylene is used as an environment-friendly ripening gas for navel oranges, oranges, bananas and other fruits;

5. Ethylene is used in drug synthesis and high-tech material synthesis.
