Products Description of TrichloroethyleneCAS#79-01-6

Trichloroethylene (TCE), also known as acetylated trichloroethylene, is a colorless, slightly sweet volatile liquid and a highly soluble solvent. It is insoluble in water but soluble in organic solvents such as ethanol and ether. It is non-flammable under normal conditions. Because of its moderate boiling point, high vapor pressure, strong stability, and suitability for gas washing operations, it is used in industry for metal cleaning (thorough degreasing) and fiber degreasing.

Taking advantage of its strong dissolving power, it is often used to remove difficult-to-remove dirt, such as semi-hardened varnish, coating polishing agent, and thicker flux; it is also used as an extractant, solvent, and low-temperature heat transfer oil medium. As a raw material intermediate, it can be used to produce tetrachloroethylene, chloroacetic acid, dichloroacetyl chloride, octachlorodipropyl ether, HCFC-123, HCFC-124, HFC-125, HFC-134a, etc.

Product Application of TrichloroethyleneCAS#79-01-6

1. Cleaning agents are developing rapidly in the metal parts and electronic components cleaning market as cleaning agents. They are mainly used in color TV, refrigerator, automobile, air conditioner, precision machinery and microelectronics industries to clean metal parts, electronic components, etc.

2. Chemical intermediates At present, as a consumption of chemical intermediates, the downstream products of trichloroethylene that have been industrially produced in China include tetrachloroethylene, hexachloroethane, dichloroacetyl chloride, octachlorodipropyl ether, HFC-134a, etc., which are mainly driven by the production of HFC-134a. Due to the rapid industrialization of HFC-134a production in China, the proportion of trichloroethylene as a chemical intermediate in the consumption structure has been greatly increased.

3. Others As solvents and extractants, their consumption accounts for about 15% of the total consumption, and are mainly used in the production of caprolactam, pesticides, and medicines. Pesticides using trichloroethylene as solvents include trichlorfon and dimethoate, which are the most popular pesticides in my country. Trichloroethylene is used as a refined extractant for the pharmaceutical intermediate-methoxyphthalate, and has also grown significantly in recent years.
