What is 4,4'-Diaminodicyclohexyl Methane?
4, 4′-Diaminodicyclohexylmethane (PACM for short) has three stereoisomers with different thermodynamic properties: anti-trans, cis-trans as well as cis-cis. Diaminodicyclohexylmethane is an important cycloaliphatic diamine, which is generally utilized to prepare cycloaliphatic dicyclohexylmethane diisocyanate (H12MDI) or directly as a healing representative for epoxy material. Diaminodicyclohexylmethane can be utilized to refine surface area products such as different environmentally friendly polyurethane coatings as well as adhesives with great openness and yellowing resistance. Epoxy resin healed by diaminodicyclohexylmethane has excellent warm resistance, dielectric residential or commercial properties, solvent resistance, mechanical properties, along with exceptional optical buildings as well as climate resistance buildings, and can be utilized in damping products, optical products, finishes, design Plastics, adhesives and other fields.
4,4 ‘- Diaminodicyclohexylmethane neutralizes acids in a weak exothermic reaction to form salts and water. May be incompatible with isocyanates, halogenated organic compounds, peroxides, phenols (acidic), epoxides, anhydrides, and acyl halides. Combining with strong reducing agents such as hydrides may produce hydrogen gas, a flammable gas.
4,4'-Diaminodicyclohexyl Methane Uses
Diaminodicyclohexylmethane can be used to process various environmentally friendly polyurethane coatings and adhesives with good transparency and resistance to yellowing. Epoxy resin cured with diaminodicyclohexylmethane has excellent heat resistance, dielectric properties, solvent resistance, mechanical properties, as well as excellent optical and weather resistance, and can be used in damping materials, optical materials, coatings, engineering plastics, adhesives, and other fields.
4,4 ‘- Diaminodicyclohexylmethane is used as an epoxy curing agent. It is a multifunctional intermediate for the production of leather, rubber products, plastics, dyes, and photosensitive polymers. It is used to manufacture diisocyanates and polyamides. It is also used as a lubricant additive and corrosion inhibitor.

Application of 4,4'-Diaminodicyclohexyl Methane
CN201610464311.2 discloses a high thermal conductivity epoxy resin-based boron nitride micro-nano composite insulating material, the preparation method of which is as follows:
1) Drying 4-4′ diaminodicyclohexylmethane (PACM), diglycidyl ether, inorganic nanoparticles and epoxy resin;
2) Mix epoxy resin and diglycidyl ether, then add 4-4′ diaminodicyclohexylmethane, and defoam after fully stirring;
3) Inorganic nanoparticles are added to the mixture in step 2), and after fully stirring, defoaming treatment is performed;
4) Ultrasonically vibrate the mixture of step 3);
5) Degassing the mixture of step 4);
6) Pour the mixture in step 5) into a mold, heat and solidify in a drying oven.
The composite insulation material has excellent thermal conductivity and can meet the heat dissipation requirements of power components. At the same time, it has the characteristics of stable electrical insulation performance and can ensure the long-term and safe operation of electrical and electronic equipment. The method has simple processing technology and good universality, and can conveniently produce high thermal conductivity epoxy resin composite insulating material.
Preparation of 4,4'-Diaminodicyclohexyl Methane
Disperse 1 g of titanium dioxide powder in a mixed solution of 40 mL of water and methanol (the volume ratio of water and methanol is 9:1), stir evenly and add 60 μmol/ml of RuCl3 x H2O dark brown aqueous solution, and control the amount so that the amount of ruthenium on the titanium dioxide The loading was 5 wt%. Seal and stir at room temperature for 3 hours, then dropwise add 1M sodium hydroxide solution to pH 10.5, continue to seal and stir for 20 hours, centrifuge and wash with a mixture of water and ethanol for 3-5 times, then vacuum dry at 60°C overnight to obtain a light green powder. catalyst.
The freshly prepared catalyst is placed in a reactor, a certain volume of solvent is added, and an appropriate amount of 4,4′-diaminodiphenylmethane (MDA) is added to control the molar ratio of ruthenium in MDA and catalyst 4 to be 10000. Close the reaction kettle and flush the reaction kettle with hydrogen for 10 times, then raise the temperature to 150°C to start the reaction, control the molar ratio of hydrogen to MDA not less than 80, and the hydrogen pressure at 1-5 MPa, and take real-time samples to detect the reaction product and conversion rate. The benzene ring in MDA can be rapidly hydrogenated to produce a single benzene ring hydrogenation product (+6H) and a double benzene ring hydrogenation product 4,4′-diaminodicyclohexylmethane (+12H) without deamination products It is worth mentioning that 4,4′-diaminodicyclohexylmethane is a raw material compound for special nylon.
