Follow me on:
N-methylpyrrolidone (N-methylpyrrolidone) also known as 1-methyl2-pyrrolidone, referred to as NMP solvent . NMP solvent is an organic compound, colorless transparent oily liquid, with a slight smell of amine. Low volatility, good thermal and chemical stability, can be volatile with water vapor. Hygroscopicity. Sensitive to light. Soluble in water, ethanol, ether, acetone, ethyl acetate, chloroform and benzene, can dissolve most organic and inorganic compounds, polar gases, natural and synthetic polymer compounds. N- methyl pyrrolidone in lithium, medicine, pesticides, pigments, cleaning agents, insulation materials and other industries are widely used in NMP solvent.

Classic Features
NMP( N-Methyl-2-pyrrolidone, N-Methylpyrrolidone, 1-Methyl-2-pyrrolidone, Methylpyrrolidone, 2-Pyrrolidinone, 1-methyl-(872-50-4) is a nitrogen-containing five-member heterocyclic compound, which has a wide range of applications because of its excellent properties as follows.
■ Large polarity, can be completely mixed and soluble in most organic solvents (alcohol, ether, ketone, aromatic hydrocarbon, chlorinated hydrocarbons, etc.), the solubility of organic matter, inorganic matter.
■ Can be mixed with water in any proportion.
■ Higher flash point than other similar solvents.
High boiling point, low freezing point, easy to use.
■ Good chemical and thermal stability, non corrosive.
Common Name
N-methyl-2-pyrrolidone (N-methyl-2-Pyrrolidone)
1-methyl-2-pyrrolidone (1-methyl-2-Pyrrolidone)
1-methyl pyrrolidine-2-One (1-methyl-Pyrrolidine-2-One)
N-methyl-2-pyrrolidinone (N-methyl-2-Pyrrolidinone)
Characteristic
■ NMP(( N-Methyl-2-pyrrolidone, N-Methylpyrrolidone, 1-Methyl-2-pyrrolidone, Methylpyrrolidone, 2-Pyrrolidinone, 1-methyl-(872-50-4) ) can be widely used in the manufacture of bulk and fine chemicals.
■ In recent years, because of the large polarity of NMP, strong solvent force, coupled with the company’s production of NMP has high purity and high quality characteristics, so it as a high-performance solvent is mainly in the field of information electronics gradually expanded.
■ With the same or even more than freon solvent to organic matter, inorganic solvent solubility, in various industrial fields, can be used as a detergent and stripping agent.
■ NMP(( N-Methyl-2-pyrrolidone, N-Methylpyrrolidone, 1-Methyl-2-pyrrolidone, Methylpyrrolidone, 2-Pyrrolidinone, 1-methyl-(872-50-4) ) as a substitute for 1,1,1, -trichloroethane, which has been used in the field of metal cleaning in the past, has attracted wide attention due to the frequent mention of the problem of environmental pollution caused by chlorine-containing solvents.
