• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Exposure could cause asphyxiation due to swelling in the throat. Inhalation may cause lung oedema.
• Uses: Terephthaloyl chloride and Isophthaloyl dichloride have many similar uses as monomers for the synthesis of specialty fibers and as raw materials for polymers such as polyamides and polyesters. Dyemanufacture; synthetic fibers, resins, films; UV absorption; pharmaceuticals; rubber chemicals; cross-linking agent for polyurethanes and polysulfides. 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.
