1-Methyl-2-Pyrrolidone

1-Methyl-2-Pyrrolidone 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 allow NMP to be used to dissolve various polymers. Specifically, N-Methylpyrrolidone is used as a surface treatment solvent for textiles, resins and metal-coated plastics, or as a paint stripper.

1.4-Butanediol

图片
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.
