Abstract

Isophthalic and terephthalic acid chlorides (also known as isophthaloyl and terephthaloyl chlorides) are without doubt strategically important compounds. One area in which they are used is the synthesis of aramid fibers employed in the production of dual-purpose functional and construction materials. These include Terlon®, SVM®, Armos®, Fenilon®, Togilen®, and Rusar®. Special requirements for the quality of target acid dichlorides and raw materials used in their synthesis often determine how these compounds are obtained. Different methods for the synthesis of iso- and terephthaloyl chlorides (including catalytic syntheses), in which different initial materials are used, are considered below. The main methods for the analysis of the above compounds are described in detail.

邻苯二甲酸二氯化物的合成方法

摘要

间苯二甲酸和对苯二甲酸酰氯（也称为间苯二甲酰氯和对苯二甲酰氯）无疑是具有战略意义的化合物。使用它们的一个领域是芳族聚酰胺纤维的合成，该芳族聚酰胺纤维用于生产双重用途的功能和建筑材料。这些包括Terlon®，SVM®，Armos®，Fenilon®，Togilen®和Rusar®。对目标酰氯及其合成中所用原料的质量有特殊要求，通常决定着如何获得这些化合物。下面考虑使用不同初始原料的合成间苯二甲酰氯和对苯二甲酰氯的不同方法（包括催化合成）。详细描述了上述化合物的主要分析方法。
