Use Mainly used in the manufacture of heat-resistant, non-toxic, underwater construction, rapid curing heat curing epoxy resin curing agent, is a polyurethane resin, synthetic functional epoxy resin raw materials, but also for rubber additives, photosensitive plastics, Pesticides, coatings, nylon products, fiber finishing agents, rust inhibitors, chelating agents, lubricants, paper processing, etc. also have applications.

Uses For the system of epoxy curing agent, photosensitive plastics, rubber chemicals, polyurethane resins and coatings; Mainly used in the manufacture of heat-resistant, non-toxic, underwater construction, rapid curing heat curing epoxy resin curing agent is Polyurethane resin, synthetic functional epoxy resin raw materials, but also for rubber additives, photosensitive plastics, pesticides, paints, nylon products, fiber finishing agents, rust inhibitors, chelating agents, lubricants, paper processing and so on.

Use MXDA's unique structure is widely used to determine its superior physical and chemical properties. MXDA and its ring hydride can be used as epoxy resin curing agent, excellent curing performance at room temperature, heat resistance, water resistance, chemical resistance and good performance, and can get a very fine transparent surface of the cured resin, low viscosity, operation Good performance. At the same time, MXDA is an important fine chemical intermediate. It can synthesize polyamides with dibasic acids and can be used to synthesize monomeric xylene diisocyanates of polyurethanes. Its benzene ring hydride can also be used for the synthesis of diisocyanates. Has been in the rubber cross-linking agent, pesticides, fiber stabilizers, surfactants, etc. used in the synthesis.

Production methods, the mixture of p-xylene for raw materials, the air and ammonia for the ammoxidation reaction between, terephthalonitrile. After being washed and dried, catalytic hydrogenation was carried out in ethanol and potassium hydroxide at a pressure of 4.5 MPa and at 90 ° C. The reaction liquid to remove the catalyst, ethanol recovery, vacuum distillation that is, between the mixed xylylenediamine.
