Dicyclohexylamine has so many uses
Dicyclohexylamine is mainly used as an intermediate in organic synthesis, and can be used to produce dye intermediates, rubber accelerators, nitrocellulose paints, pesticides, catalysts, preservatives, vapor phase corrosion inhibitors and fuel antioxidant additives. It is used to manufacture rubber vulcanization accelerator, insecticide, catalyst, preservative, etc., and also used as insecticide, acid gas absorbent and steel rust inhibitor. The fatty acid salts and sulfates of dicyclohexylamine have the detergency of soap and are used in printing and dyeing and textile industry. Its metal complex is used as a catalyst for ink and paint.

How to prepare dicyclohexamine
The hydrorefining reactor was a tubular fixed bed reactor with an inner diameter of 20mm. The catalyst was a nickel-based highly active catalyst with a fixed volume of 15mL. The catalyst was installed in the isothermal zone of the reactor. The particle size was 20-40 mesh, and the mass ratio of metal elements was Ni∶Al∶Mo = 85∶5∶5.

The difference between cyclohexamine and dicyclohexamine
Dicyclohexamine, also known as dodecahydrodiphenylamine. Colorless transparent oily liquid. It smells fishy. Molecular weight 181.32. Boiling point 254 ~ 255℃. The relative density is 0.9104(25/25℃). Refractive index 1.4842. Flash point 9Chemicalbook6℃. Can be miscible with ethyl ether, cyclohexylamine, soluble in ethanol and benzene, insoluble in water. It is mainly used in the synthesis of rubber accelerator, metal corrosion inhibitor, surfactant, medicine and pesticide. It's made by reacting cyclohexanol with ammonia and hydrogen. It can also be prepared by catalytic hydrogenation of aniline.
