说明

一般說明

Trichloroethylene (TCE) is a chlorine containing organic compound, widely employed as an industrial solvent. TCE is formed as a major intermediate during the biodegradation of tetrachloroethylene (PCE) in a small anaerobic continuous-flow fixed film column.

應用

Trichloroethylene may be employed for various industrial processes, such as metal cleaning and degreasing. It may be used to synthesize chloroacetic acid.
