[Physical properties of trichloroethylene]
Trichloroethylene is a colorless transparent liquid that belongs to the six categories of drugs. At present, the production method mainly uses calcium carbide method and ethylene method in China.
Trichloroethylene is an excellent solvent, mainly used as an electron and electroplating cleaning agent, metal surface degreaser, metal electroplating cleaning agent, metal electroplating before painting, and battery industry extractant.
It is used as an anesthetic in medicine and as a raw material for the synthesis of monochloroacetic acid, a pesticide intermediate, in pesticides. It is used as an extractant in the production of caprolactam;
Note: It should be noted that trichloroethylene is insoluble in water, and water cannot be added when used, otherwise there will be delamination.


FAQ - Technical & Supply Chain
-
Q:
How is the stability of Trichloroethylene CAS 79-01-6 maintained for metal cleaning?
A: For industrial applications, trichloroethylene is typically supplied with specialized stabilizers (such as neutral inhibitors) to prevent decomposition. This ensures the substance remains chemically stable when exposed to heat, moisture, and various metallic fines (like aluminum or zinc) during continuous vapor degreasing cycles, maintaining its efficacy as a chlorinated solvent. -
Q:
What are the primary industrial usage boundaries for this chemical?
A: This product is intended strictly for industrial use as a heavy-duty solvent and chemical intermediate. Its application is typically confined to controlled vapor degreasing equipment or closed-loop extraction systems designed to manage volatility and exposure. It is not intended for consumer use or open-air applications due to its specific chemical profile and regulatory classification.
