How is N-Methylpyrrolidone Used

N-Methylpyrrolidone is a colorless to light yellow transparent liquid, highly hygroscopic, miscible with most organic solvents such as water, ethanol, ether, acetone, ethyl acetate, chloroform and benzene. Chemically stable, but acid or alkali will rupture the lactam ring.

NMP is used to recover certain hydrocarbons generated during the processing of petrochemicals, such as the recovery of 1,3-butadiene and acetylene. NMP can be used to absorb hydrogen sulfide from acid gases and hydrodesulfurization facilities. Its good solvency properties have led to NMP being used to dissolve various polymers. Specifically, NMP is used as a solvent for surface treatment of textiles, resins and metal-coated plastics, or as a paint stripper.

1.4-Butanediol

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

Tetrahydrofuran (THF) is a colorless, volatile liquid with the odor of ether or acetone and is miscible with water and most organic solvents. THF is highly flammable and may thermally decompose into carbon monoxide and carbon dioxide.
