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):

N-methylaniline is the main product of n-alkyl aromatic amine series. It is an important intermediate of fine chemical industry and has a wide range of uses. N-methylaniline is a colorless oily liquid at room temperature, which is soluble in ethanol, ether and chloroform, insoluble in water and not easy to evaporate. However, it is not conducive to distribution in the cylinder of multi cylinder engine. It has stable properties and is not easy to decompose in air and dark environment. The main characteristics of blended gasoline with N-methylaniline antiknock agent are odor, high density, unstable unwashed gum and low olefin value, which need auxiliary antiknock agents such as MTBE and MMT. N-methylaniline is a widely used fine chemical product. It is mainly used in the production of pesticides, dyes, dye intermediates, rubber additives and explosives. It can also be used as solvent and acid acceptor, as organic synthesis intermediates, acid absorbents and solvents. It is used in the production of cationic brilliant red FG, Cationic Pink B and reactive yellow brown kGr in dye industry. It can also be used to improve the octane number of gasoline, organic synthesis and solvent.

Phenylhydrazine is used in pesticide production to synthesize 1-phenylaminourea, the intermediate of Triazophos and 1-phenyl-3,6-dihydroxypyridazine, the intermediate of pyridazinon. It is also the intermediate of oxazolidone and imidazolidone, a new fungicide. In addition, phenylhydrazine, as an organic synthetic raw material, is also used as an intermediate in dye, medicine and other industries, as well as an analytical reagent.
