说明

一般描述

Tetrachloroethylene is a chlorinated ethene derivative mainly found in the contaminated groundwater[1] due to its extensive use as a dry cleaning solvent.[2] Its sorption and reduction kinetics with zero-valent iron has been determined in a closed, anaerobic batch system.[3]

Tetrachloroethylene, a chlorinated ethylene, is a common industrial solvent. It is also one of the major contaminant found in groundwater supplies.[4]

应用

TCE may be used as a metal cleaning or degreasing agent.[5]

Tetrachloroethylene (TCE) was employed as solvent to investigate the NMR spectra of end functionalized cyclopentadienyl poly(ethylene) (PE-Cp).[6]
