General description

Tetrachloroethylene is a chlorinated ethene derivative mainly found in the contaminated groundwater due to its extensive use as a dry cleaning solvent. Its sorption and reduction kinetics with zero-valent iron has been determined in a closed, anaerobic batch system.
Tetrachloroethylene, a chlorinated ethylene, is a common industrial solvent. It is also one of the major contaminant found in groundwater supplies.

Application

Tetrachloroethylene (TCE) was employed as solvent to investigate the NMR spectra of end functionalized cyclopentadienyl poly(ethylene) (PE-Cp).
TCE may be used as a metal cleaning or degreasing agent.
