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.

Why is dicyclohexylamine so scarce? Turns out it has so many uses!
Dicyclohexylamine is a fine chemical intermediate with a wide range of uses. In the past, due to the lack of domestic resources, little attention was paid to its research and application. Dicyclohexylamine at home and abroad is usually a by-product of cyclohexylamine production. In my country, catalytic hydrogenation of aniline is generally used to synthesize cyclohexylamine, and dicyclohexylamine is co-produced at the same time. Depending on the reaction conditions and catalysts, different proportions of cyclohexylamine and dicyclohexylamine can be obtained. If they are not deliberately adjusted, they can generally be by-products. About 10% of dicyclohexylamine is obtained.

Cyclohexamine product condition
Cyclohexamine is a colorless liquid with a strong fishy odor. Soluble in water, miscible soluble in most organic solvents. Cyclohexamine is an important organic chemical raw material and fine chemical intermediate, is the downstream product of aniline, mainly used in the preparation of cyclohexanol, cyclohexanone, caprolactam, desulfurizer, emulsifier, preservative, antistatic agent, latex coagulant, petroleum additives, can be used as dye and pesticide fungicide, insecticide intermediate, can also be used as a synthetic fiber and plastic raw material.

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.
