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.
