一般說明

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。

應用

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 。

The objective of this study is to demonstrate the feasibility of microcapsules containing a protein and a proteinase inhibitor in order to allow the oral administration of proteic or peptidic drug. Starch/bovine serum albumin mixed-walled microcapsules were prepared using interfacial

Journal of microencapsulation, 11(2), 213-224 (1994-03-01)
Microcapsules were prepared from three proteins, namely human serum albumin (HSA), bovine fibrinogen and ovalbumin, by an interfacial crosslinking process using terephthaloylchloride. They were further treated with alkaline hydroxylamine in order to disrupt ester and anhydride bonds in the walls.
N Pariot et al.
International journal of pharmaceutics, 211(1-2), 19-27 (2001-01-04)
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)

Journal of pharmaceutical sciences, 80(6), 578-585 (1991-06-01)
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
