Why is N-methylpyrrolidone so popular?
First of all, the consumption direction of NMP conforms to the development trend of China. N-methylpyrrolidone accounts for more than 80% of the consumption in the lithium battery industry, and it is a product with absolute voice. In addition, it has its presence in the polymer industry, the pharmaceutical industry, and the electronics industry. Although it does not account for a large proportion in the lithium battery industry, it is also a product with weight.

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.
