Brief introduction:

4,4 '-diaminodicyclohexylmethane (PACM) has three stereoisomers with different thermodynamic properties: inverse, cis-trans and cis. Diaminodicyclohexylmethane is an important alicyclic diamine, which is mainly used in the preparation of alicyclic dicyclohexylmethane diisocyanate (H12MDI) or as curing agent for epoxy resin.

Application:

Diaminobicyclohexylmethane can be used to process all kinds of environmentally friendly polyurethane coatings and adhesives with good transparency and yellowing resistance. The epoxy resin cured by diaminodicyclohexylmethane has excellent heat resistance, dielectric property, solvent resistance, mechanical properties, as well as excellent optical properties, weather resistance, and can be used in damping materials, optical materials, coatings, engineering plastics, adhesives and other fields.

Preparation:

1g titanium dioxide powder was dispersed in a mixture of 40mL water and methanol (volume ratio of water to methanol was 9:1), and then 60μmol/ml RuCl3·xH2O dark brown aqueous solution was added after mixing evenly. The addition amount was controlled so that the load of ruthenium on titanium dioxide was 5wt %. After 3 hours of sealing and stirring at room temperature, add 1M sodium hydroxide solution to pH10.5, continue sealing and stirring for 20 hours, centrifuge and wash the mixture of water and ethanol for 3-5 times, and dry the light green powder overnight at 60℃ under vacuum to obtain the catalyst. The freshly prepared catalyst was placed in the reactor, a certain volume of solvent was added, and an appropriate amount of 4,4 '-diaminodiphenylmethane (MDA) was added, and the molar ratio of ruthenium in MDA and catalyst 4 was controlled to 10000. The closed reactor was rinsed with hydrogen for 10 times and then heated to 150℃ to start the reaction. The molar ratio of hydrogen and MDA was controlled to be no less than 80, and the hydrogen pressure was 1 ~ 5MPa. The reaction products and conversion rate were detected by real-time sampling. The benzene ring in MDA can be rapidly hydrogenated to produce a single benzene ring hydrogenation product (+6H) and a diphenyl ring hydrogenation product (+12H) without deamination. It is worth noting that 4,4 '-diaminodicyclohexylmethane is a raw material compound of special nylon.
