Description

General description

Trichloroethylene (TCE) is a chlorinated ethylene compound commonly used as a dry cleaning and degreasing solvent.[17] 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.[27][31] Various methods have been reported for its synthesis. One of them is by chlorinating ethylene dichloride.[27] 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.[97] Its toxicity and carcinogenicity has been studied.[01][02]
Many methods have been proposed for the mineralization of TCE.[03][04][05][06]
