一般描述

对苯二甲酰氯是一种源自对苯二甲酸的高反应性酰氯。它在聚合物合成中用作交联剂。对苯二甲酰氯与双官能团α,ω-二氨基聚苯乙烯发生缩合反应，沿着聚合物主链生成含有酰胺键的扩链聚苯乙烯。它与牛血清白蛋白发生界面反应，形成交联薄膜。

应用

对苯二甲酰氯通过环状取代 双 （4-羟基苯基）对苯二甲酸酯的二氰酸酯化合物进行热环三聚反应，以用于合成液晶热固性化合物 。

Microcapsules were prepared by interfacial cross-linking of beta-cyclodextrins (beta-CD) with terephthaloyl chloride (TC). Batches were prepared from beta-CD solutions in 1 M NaOH, using 5% TC and a 30 min reaction time. Microcapsules were studied with respect to morphology (microscopy)

Fourier transform infrared (FT-IR) spectroscopic studies were performed on microcapsules prepared through interfacial cross-linking of human serum albumin (HSA) with terephthaloylchloride at various pH values (5.9 to 11). Correlations were established with morphology and size of microcapsules. Increasing polycondensation pH
