Uses:

Paraphthalonitrile is a kind of phthalonitrile compound. Phthalonitrile is an important chemical product, mainly including m-phthalonitrile, o-phthalonitrile or p-phthalonitrile; As an excellent intermediate in organic chemistry, aromatic nitriles have been widely used in biology, medicine, pesticides, functional materials and other fields.

Paraphthalonitrile is also an important chemical organic raw material. Paraphthalonitrile can be hydrogenated to obtain p-phenylenediamine, which is an important raw material of polyamide and a good curing agent for epoxy resin; The terephthalic acid can be obtained by hydrolysis of phthalonitrile, which can be used to produce polyester resin, polyester fiber, film, insulating paint, engineering plastics, plasticizer, etc; Tetrachloro-p-phenylenedinitrile can be obtained by reacting p-phenylenedinitrile with chlorine, and can be used to synthesize herbicides, insecticides and drugs.
