Trichloroethylene is an important chemical raw material, widely used in manufacturing, cleaning, solvents and other fields. In the upstream and downstream industry chain of trichloroethylene, a variety of related products are involved. This article will detail the upstream and downstream associated products of trichloroethylene.

1. Upstream Associated Products

1. Vinyl chloride

Vinyl chloride is one of the main raw materials of trichloroethylene, which is produced by the reaction of chlorination and ethylene. Vinyl chloride is also an important chemical raw material, which can be used to produce plastic products such as polyvinyl chloride (PVC).

2. Chlorine

Chlorine is another important raw material in the production of trichloroethylene. It reacts with ethylene to produce vinyl chloride, and then further reacts to produce trichloroethylene.

2. Downstream Associated Products

1. Tetrachloroethylene

Tetrachloroethylene is one of the downstream products of trichloroethylene, which is made by introducing another chlorine atom into trichloroethylene. Tetrachloroethylene is also an important solvent and cleaning agent, which can be used in dry cleaning, metal cleaning and other fields.

2. Trichloroethane

Trichloroethane is another downstream product of trichloroethylene, which is produced by introducing a hydrogen atom into trichloroethylene. Trichloroethane can be used as a solvent, anesthetic, refrigerant, etc.

3. Chlorinated hydrocarbon solvent

trichloroethylene can also be used to produce a series of chlorinated hydrocarbon solvents, such as 1,1,1-trichloroethane, 1,1-dichloroethane, etc. These solvents are widely used in cleaning, coatings, adhesives and other fields.

In short, the upstream and downstream related products of trichloroethylene are very extensive, involving a variety of chemicals and solvents. In the process of production and use, it is necessary to fully understand the nature and use of these related products to ensure safe production and reasonable use.
