N-methyl pyrrolidone

N-methylpyrrolidone is an organic substance. It is a colorless to yellowish transparent liquid with a slight smell of ammonia. It is miscible with water in any proportion. It is soluble in ether, acetone, esters, halogenated hydrocarbons, aromatic hydrocarbons and other organic solvents. It is almost completely mixed with all solvents.

Phthalic anhydride

Phthalic anhydride, an organic compound, is a cyclic anhydride formed by dehydration of phthalic acid molecules. It is a white crystalline powder, insoluble in cold water, slightly soluble in hot water, ether, ethanol, pyridine, benzene, carbon disulfide, etc. It is an important organic chemical raw material and an important intermediate for preparing phthalate ester plasticizers, coatings, saccharin, dyes and organic compounds.

Polyvinylidene fluoride

Polyvinylidene fluoride (PVDF) is a highly non reactive thermoplastic fluoropolymer. It can be synthesized by polymerization of 1,1-difluoroethylene. Soluble in strong polar solvents such as dimethylacetamide. Anti aging, chemical resistance, weather resistance, UV radiation resistance and other excellent performance. It can be used as engineering plastics, anti-corrosion equipment for sealing rings, capacitors, coatings, insulating materials, ion exchange membrane materials, etc.

Propylene oxide

Propylene oxide is a colorless ether flavored liquid with low boiling point, flammability and chirality. Industrial products are generally racemic mixtures of two enantiomers. It is partially miscible with water, ethanol and ether. It forms a binary azeotropic mixture with pentane, pentene, cyclopentane, cyclopentene and dichloromethane. Toxic, irritating to mucous membrane and skin, can damage cornea and conjunctiva, cause respiratory system pain, skin burn and swelling, and even tissue necrosis.

Methyl ethyl ketone (MEK)

Methyl ethyl ketone is an organic compound with a molecular weight of 72.11. It is a colorless transparent liquid with an odor similar to acetone. Volatile. It is miscible with ethanol, ether, benzene, chloroform and oil. Soluble in 4 parts of water, but the solubility decreases when the temperature rises, and can form an azeotropic mixture with water. Low toxicity, median lethal dose (rat, oral) 3300mg/kg. Flammable, vapor can form explosive mixture with air. High concentrations of steam are anesthetic.

Dimethyl carbonate (DMC)

Dimethyl carbonate, an organic compound, is a chemical raw material with low toxicity, excellent environmental protection performance and wide use. It is an important organic synthesis intermediate. Its molecular structure contains carbonyl, methyl, methoxy and other functional groups. It has a variety of reaction properties. It is safe, convenient, less polluting, and easy to transport in production.
