Cyclohexene;  Cyclohexylamine;  Preparation method

Cyclohexylamine is a widely used fine chemical product, in order to continuously improve the preparation technology of cyclohexylamine in China, briefly introduced the main preparation methods of cyclohexylamine: aniline catalytic hydrogenation, cyclohexanol vapor phase ammoniation method and cyclohexanone catalytic ammonilysis method, etc., pointing out that the future development trend will be aniline electrolytic reduction method, which is simple and has very little pollution. In addition, the research progress of the preparation of cyclohexylamine from direct ammoniation of cyclohexene is briefly introduced.
