N-Methyl pyrrolidone is an organic compound with low volatility, good thermal and chemical stability, and can evaporate with water vapor. It is hygroscopic. Sensitive to light. It is easily soluble in water, ethanol, ether, acetone, ethyl acetate, chloroform and benzene, and can dissolve most organic and inorganic compounds, polar gases, natural and synthetic polymer compounds. N-methylpyrrolidone is miscible with water in any ratio, and is completely mixed with almost all solvents and is miscible with alcohol, ether, acetone, etc.
It is miscible with water, alcohol, ether, ester, ketone, halogenated hydrocarbon, aromatic hydrocarbon and castor oil. Low volatility, good thermal and chemical stability, and can evaporate with water vapor. It is hygroscopic. Sensitive to light. The median lethal dose (rat, oral) is 3914 mg/kg.
1) 1,4- γ-butyrolactone can be obtained from butanediol through catalytic dehydrogenation:
2) NMP can be obtained from the reaction of butyrolactone and methylamine under high temperature and high pressure conditions:
N-methylpyrrolidone (NMP) is a nitrogen heterocyclic compound with a series of excellent physical and chemical properties. It is non-toxic, high boiling point, strong polarity, low viscosity, low corrosiveness, high solubility, and low volatility. It is a high-efficiency selective solvent with good stability and easy recovery. Electronic grade NMP is mainly applied as a solvent for polyvinylidene fluoride, and as an electrode auxiliary for lithium ion batteries material. It can be used for photoresist removal liquid, LCD liquid crystal material production: solvent in pharmaceutical production; the cleaning of precision instruments and circuit boards in the semiconductor industry.
