Descripción

General description

Trichloroethylene (TCE) is a chlorinated ethylene compound commonly used as a dry cleaning and degreasing solvent. Without stabilizers, TCE is unstable and degrades easily in the presence of moisture air, light and heat, it can be minimized by adding diisopropylamine as a stabilizer. Various methods have been reported for its synthesis. One of them is by chlorinating ethylene dichloride. Since TCE is one of the most common industrial solvent it has led it to be a major contaminant found in the ground water. It has adverse effect on human health due to its potential toxicity and carcinogenicity. Its toxicity and carcinogenicity has been studied.
Many methods have been proposed for the mineralization of TCE.
