2-pyrrolidone

Alpha pyrrolidone is an important chemical raw material and strongly polar organic solvent, widely used in industries such as pharmaceuticals, textiles, cosmetics, solvents, and electronic cleaning.

N-methylpyrrolidone

N-methylpyrrolidone

NMP belongs to nitrogen heterocyclic compounds and has a series of excellent physical and chemical properties. It is a non-toxic, high boiling point, strong polarity, low viscosity, low corrosiveness, high solubility, low volatility, good stability, and easy to recover high-efficiency selective solvent.

aniline

It is a compound formed by replacing one hydrogen atom in a benzene molecule with an amino group. Its physical properties are colorless or slightly yellow oily liquid, with a strong odor. Its chemical properties are alkaline, and it can react with hydrochloric acid to form a hydrochloride salt, and with sulfuric acid to form a sulfate salt. Aniline turns brown when exposed to air or sunlight. Steam distillation can be used, and a small amount of zinc powder can be added during distillation to prevent oxidation. The purified aniline can be added with 10-15 ppm NaBH4 to prevent oxidation and deterioration.

Triethylamine

A type of amine organic compound, systematically named N, N-diethylethylamine, is a colorless transparent liquid with a strong ammonia odor and emits a slight smoke in the air. Slightly soluble in water, soluble in ethanol and ether. The aqueous solution is weakly alkaline. Flammable and explosive. Toxic and highly irritating.
