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.

Determination of peroxide in tetrahydrofuran
Tetrahydrofuran and ether are easy to produce peroxide when stored for a long time. Be careful when using. Be sure to detect the peroxide content in the solution first. If more than 0.05% peroxide is present, the peroxide must be removed before distillation. If the peroxide content is 1% or higher, it must be treated by incineration.

The role of NMP in the battery
The most commonly used solvent in the pre-treatment of lithium-ion batteries is NMP, commonly known as methyl, known as N-methylpyrrolidone, and the molecular formula is C5H9NO. The role of NMP in the battery: as a PVDF solvent, participate in the dispersion of the slurry, form a uniform medium, and maintain a stable slurry for a long time in a certain viscosity range.

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.
