Application | 3,3 '-dimethyl-4, 4-diaminodicyclohexylmethane, it is mainly used in epoxy resin curing agent, such as high-grade polishing accessories glue, ship paint, heavy anti-corrosion and other industrial paints, as well as wind blade curing agent, wind mold material curing agent and so on. It is also applied to the synthesis of Polyaspartic acid esters, polyamides and the like. The polyurethane synthesized by MACM not only has the elasticity of rubber, but also has the strength and excellent processing performance of plastic, especially in sound insulation, heat insulation, wear resistance, oil resistance, elasticity and other aspects for the advantages of other materials can not be compared; The synthesis of polyamide with non-toxic, light characteristics, at the same time has excellent mechanical strength, good wear resistance and corrosion resistance. In recent years, the application of MACM at home and abroad has expanded rapidly, and MACM with good production performance obviously has great industrial and commercial value. |
preparation | in an autoclave with a volume of 6000L, add 2000kg 3,3 '-dimethyl -4,4'-diaminodiphenylmethane and 2000kg of tetrahydrofuran, and then 100kg of 5% Ru/Al2O3 catalyst and 100kg of aluminum ammonium sulfate are added. After sealing, hydrogen is used to replace the air in the autoclave, and then 6MPa hydrogen is introduced, the autoclave was heated to 160 ° C., the pressure in the autoclave was maintained at 8MPa by adjusting the hydrogen valve, and the reaction was vigorously stirred for 4 hours. After cooling, the sample was sampled and measured by gas chromatography-mass spectrometry. As a result, the conversion of 3,3 '-dimethyl-4, 4-diaminodicyclohexylmethane was 100%, and the yield of MACM was 99.4%. |
