Application fields and main uses

The monomer of synthetic special fiber is the main raw material of aramid 1414. Aramid is widely used downstream: in aerospace field, ship and automobile industry; As bulletproof products, it can be used to make hard bulletproof armor plate and soft bulletproof vest; It can be used in infrastructure and building materials, aramid reinforced concrete, aramid reinforced wood, conveyor belt, cable, special protective clothing, sports equipment, electronic equipment, etc.

Typical Properties

Terephthaloyl chloride (TCL, 1,4-benzenedicarbonyl chloride) is the acid chloride of terephthalic acid and is one of two monomers used to make Kevlar(R), the other being p-phenylenediamine. Its CAS reference number is 100-20-9 and its chemical formula is C8H4Cl2O2. TCL is used as a key component in performance polymers and aramid fibers, where it imparts flame resistance, chemical resistance, temperature stability, light weight, and very high strength. TCL is also an effective water scavenger, used to stabilize isocyanates and urethane prepolymers. TCL is a white crystalline solid at room temperature, soluble in common organic solvents. Its melting point is 81.5-83 °C, its boiling point is 265 °C. It is corrosive. TCL is used for making various copolymers and aramid polymers such as Heracron, Twaron and Kevlar(R):
