N-Methyl-2-pyrrolidone (NMP) is an organic compound also known as 1-methyl-2-pyrrolidone. Its chemical formula is C5H9NO and its molecular weight is 99.13. At normal temperature, NMP is a colorless to light yellow transparent liquid with a slight ammonia odor. It has good solubility and can be almost completely mixed with various organic solvents such as water, ethanol, ether, acetone, esters, halogenated hydrocarbons, aromatic hydrocarbons, etc.

NMP is widely used in chemical, pharmaceutical, pesticide, pigment, cleaning agent, insulation materials and other industries. For example, it can be used as a solvent to produce lithium-ion battery electrodes, and can also be used to remove aromatics from lubricating oil fractions, and to remove alkanes from kerosene fractions, etc. In addition, NMP can also be used as a solvent for the separation and recovery of synthesis gas, aromatics and butadiene from hydrocarbon cracking gas, refinery gas and natural gas, as well as the production of some other fine chemicals.

It should be noted that although NMP is used in many fields, it also has certain toxicity and irritation. Therefore, appropriate safety measures need to be taken during use.
