产品描述

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。

四氯乙烯可以用作锂离子电池制造中的成膜电解质添加剂。它也可以用作通过傅立叶变换红外光谱(FT-IR)估算水中油脂的提取剂。

General description

Tetrachloroethylene (perchloroethylene, PCE), is a chlorinated ethylene compound commonly used as a dry cleaning and degreasing solvent.[1] It shows IR transparency as it has no C–H bonds making it an ideal solvent for IR spectroscopy.[2][3] PCE is a man-made pollutant which is difficult to degrade.[4] It is a ground water contaminant[7] which has adverse effect on human health due to its potential toxicity and carcinogenicity.[6] Some of the methods proposed for its degradation are Fenton oxidation treatment,[5] reductive dehalogenation under methanogenic condition,[6] and reduction using zero valent metal ions.[7] One of the methods reported for its synthesis is by reacting ethylene dichloride and chlorine.[8]

Application

Tetrachloroethylene may be used as a film-forming electrolyte additive in the manufacture of lithium ion batteries.[9] It may also be used as an extractant for the estimation of oil and grease in water by Fourier transform infrared spectroscopy (FT-IR).[2]
