General description

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.

Application

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

Tetrachloroethylene (PCE) and trichloroethylene (TCE), common industrial solvents, are among the most frequent contaminants found in groundwater supplies. Due to the potential toxicity and carcinogenicity of chlorinated ethylenes, knowledge about their transformation potential is important in evaluating their environmental fate.
