Introduction and properties of dimethylacetamide
Dimethylacetamide, the full name is N,N-dimethylacetamide (chemical formula: CH3C(O)N(CH3)2, abbreviated as Dmac or DMA. A commonly used aprotic polar solvent. Colorless transparent liquid, flammable. Can be used with Organic solvents such as water, alcohol, ether, ester, benzene, chloroform and aromatic compounds can be mixed at will. It is used in pharmaceuticals, synthetic resins, and is also used as a solvent for polyacrylonitrile spinning and the extraction of styrene from the carbon eight fraction. Distilled solvents, etc. are produced by the action of diamine and acetyl chloride.

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.

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.
