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.

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.

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.

Battery Grade Lithium Hydroxide Introduction and Comparison
Lithium hydroxide is one of the three basic lithium salts in the lithium industry chain. Its main forms are anhydrous lithium hydroxide and lithium hydroxide monohydrate. Battery-grade lithium hydroxide monohydrate is mainly used in the preparation of cathode materials for lithium-ion batteries. It is also used as an additive in alkaline battery electrolytes and in the manufacture of lithium.

The role of NMP in the production process of lithium batteries
N-methylpyrrolidone (NMP) is a very important auxiliary material in the production of lithium battery cathode materials. It is a commonly used solvent in the formulation stage of lithium battery cathode materials. According to the lithium battery production process, during the coating and baking stage of lithium battery cathode material production, under the action of circulating hot air, the cathode solvent N-methylpyrrolidone will all volatilize at high temperatures. The gas phase containing NMP is collected and treated through condensation, water spraying, wheel adsorption and concentration and other gas phase collection and treatment measures to form organic liquid containing NMP. By discussing the role, production method, consumption point and purification method of N-Methyl-alpha-pyrrolidonein the production process of lithium battery cathode materials, we hope to achieve on-site purification, conversion and reuse of NMP organic liquid, which can reduce the cost of raw materials and achieve the reduction of lithium battery production enterprises. This efficiency increase.
