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.

Brief description of THF
Tetrahydrofuran (THF) is widely used because of its low toxicity, low boiling point and good fluidity. It has strong solubility in many chemicals and good diffusion and permeability to the surface and inside of the resin. It can dissolve all compounds except polyethylene, polypropylene and fluororesin, especially for polyvinyl chloride, polyvinylidene chloride and styrene-butadiene rubber.

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.
