| Hazard Information | Back Directory | [Chemical Properties]
white crystalline flakes | [Preparation]
Synthesis of terephthaloyl chloride by thionyl chloride method: terephthalic acid is mixed with thionyl chloride, refluxed at 80℃ for 10-12h, then the thionyl chloride is evaporated, and the resulting crude product is distilled under reduced pressure to obtain the finished product. | [General Description]
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. | [Hazard]
Skin irritant. | [Flammability and Explosibility]
Nonflammable | [Purification Methods]
Crystallise the acid chloride from dry hexane. [Beilstein 9 IV 3318.] |
