对苯二甲酰氯制备方法综述

A Review of Preparation of Terephthaloyl Chloride

对苯二甲酰氯是芳香族羧酸的衍生物,是重要的有机合成原料和化学中间体,可用于制备耐高温树脂、绝缘材料、染料、颜料、医药、农药等。对几种制备酰氯的方法进行了论述,如最常用的氯化亚砜法、三氯化磷法、五氯化磷法、三光气法等。

The terephthaloyl chloride is an aromatic carboxylic acid derivative, and it is an important raw material for organic synthesis and chemical intermediate for the preparation of resin with high-temperature resistance, insulation materials, dyes, pigments, pharmaceuticals, pesticides, etc. The most commonly used methods for preparing acyl chloride are discussed, such as thionyl chloride method, phosphorus trichloride method, phosphorus pentaehloride method, triphosgene method, etc.
