Precautions for use and operation of cyclohexylamine

As cyclohexylamine is irritating to the skin and mutagenic to the human body, the staff shall wear a direct gas mask (half mask), chemical safety goggles, anti-corrosion work clothes, rubber oil resistant gloves and conduct airtight operation in strict accordance with the operating procedures in daily work contact. The working environment shall be ventilated to avoid kindling and heat source.

Composition and function of cyclohexylamine corrosion and scale inhibitor

In industry, cyclohexylamine is prepared by aniline catalytic hydrogenation, and the commonly used catalyst is cobalt. It can also be divided into two methods: atmospheric pressure and pressurization. In the atmospheric method, the molar ratio of aniline to hydrogen is 1:2, the addition reaction temperature is 150~180 ℃, and the pressure in the reactor is atmospheric. In the pressurization method, the molar ratio of aniline to hydrogen is 1:10, the addition reaction temperature is about 240 ℃, and the pressure in the reactor is 14.61MPa. The fixed bed liquid phase hydrogenation method is adopted.

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.
