四氯乙烯（全氯乙烯，PCE）是一种氯化乙烯化合物，通常用作干洗和脱脂溶剂。 它显示出红外透明性，因为它没有C–H键，是红外光谱的理想溶剂。 PCE是一种难以降解的人为污染物。 它是一种地下水污染物，由于其潜在的毒性和致癌性而对人体健康产生不利影响。 建议的降解方法包括芬顿氧化处理，产甲烷条件下的还原性脱卤化以及使用零价金属离子的还原。 报道的合成方法之一是使二氯化乙烯与氯反应。
Tetrachloroethylene (perchloroethylene, PCE), is a chlorinated ethylene compound commonly used as a dry cleaning and degreasing solvent. It shows IR transparency as it has no C–H bonds making it an ideal solvent for IR spectroscopy. PCE is a man-made pollutant which is difficult to degrade. It is a ground water contaminant which has adverse effect on human health due to its potential toxicity and carcinogenicity. Some of the methods proposed for its degradation are Fenton oxidation treatment, reductive dehalogenation under methanogenic condition, and reduction using zero valent metal ions. One of the methods reported for its synthesis is by reacting ethylene dichloride and chlorine.
Tetrachloroethylene may be used as a film-forming electrolyte additive in the manufacture of lithium ion batteries. It may also be used as an extractant for the estimation of oil and grease in water by Fourier transform infrared spectroscopy (FT-IR).
