colorless liquid. There is almond taste. It is yellow in the air. Boiling point 248 °c. The relative density was 1. 055. Refractive index 5700. The viscosity is similar to that of dibutyl phthalate. Soluble in water and organic solvents.
A mixture of M-xylene and p-xylene is used as a raw material to produce m-terephthalonitrile by an ammoxidation reaction of air and ammonia. After washing and drying, the catalytic hydrogenation was carried out in ethanol and potassium hydroxide solvent at a pressure of 4. 5MPa and 90 ℃. The catalyst was removed from the reaction solution, and ethanol was recovered, followed by distillation under reduced pressure to obtain p-mixed xylylenediamine.
used in the manufacture of epoxy resin curing agent, photosensitive plastics, rubber additives, polyurethane resin and coatings.

MXDA and its cyclic hydride can be used as epoxy resin curing agent. It has excellent room temperature curing performance, good heat resistance, water resistance, and chemical corrosion resistance, and can obtain a transparent surface with extremely finished curing resin, low viscosity, Good operating performance. At the same time, MXDA is an important fine chemical intermediate, which can synthesize polyamide with dibasic acid, can synthesize polyurethane monomer m-xylene diisocyanate, and its benzene ring hydride can also be used to synthesize diisocyanate. At present, it has been used in the synthesis of rubber crosslinking agents, pesticides, fiber stabilizers, surfactants, etc. |
production method | using a mixture of meta and p-xylene as raw materials, the ammonia oxidation reaction between air and ammonia produces meta and terephthalonitrile. After washing and drying, catalytic hydrogenation is carried out in ethanol and potassium hydroxide solvent at 4.5MPa pressure and 90 ℃. The reaction liquid removes the catalyst, recovers the ethanol, and distilled under reduced pressure to obtain the mixed phenylxylylenediamine. |
