Why is dicyclohexylamine so scarce?

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.

The rapid increase in the production capacity of the cyclohexylamine unit will inevitably lead to an increase in by-product dicyclohexylamine resources. Therefore, it is very important and necessary to develop the application of dicyclohexylamine and expand its market. Dicyclohexylamine is mainly used in the fields of synthetic rubber accelerators, metal corrosion inhibitors, surfactants, oilfield chemicals, medicines and pesticides. With the advancement of science and technology, its new applications are constantly being developed, and most of the fine chemicals synthesized with it are new products with promising development prospects.
