용도

Terephthaloyl chloride acts as a monomer with p-phenylenediamine used in the preparation of polymer viz. poly paraphenylene terephthalamide. It is an active component in performance polymers and aramid fibers, which gives flame resistance, chemical resistance, temperature stability, light weight, and very high strength. It is also used as an effective water scavenger, utilized to stabilize isocyanates and urethane prepolymers. Further, it is used in the preparation of liquid crystalline thermosets by thermal cyclotrimerization of dicyanate compounds of ring substituted bis(4-hydroxyphenyl) terepthalates. In addition to this, it is involved in the condensation reaction with difunctional alfa, µ-diaminopolystyrene to get chain-extended polystyrene containing amide bonds along the polymer backbone.

참고

Incompatible with alcohols, oxidizing agents, water and strong bases.
