Descrição geral

Terephthaloyl chloride is a highly reactive acid chloride derived from terephthalic acid. It is used as a cross-linking agent in polymer synthesis. Terephthaloyl chloride undergoes condensation reaction with difunctional α,ω-diaminopolystyrene to yield chain-extended polystyrene containing amide bonds along the polymer backbone. It undergoes interfacial reaction with bovine serum albumin to form thin cross-linked films.

Aplicação

Terephthaloyl chloride was used in the synthesis of liquid crystalline thermosets by thermal cyclotrimerization of dicyanate compounds of ring substituted bis(4-hydroxyphenyl) terepthalates.

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.

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)
