N-Methyl-2-Pyrrolidone (NMP)


As a chemically stable and strong polar solvent, N-Methyl-2-Pyrrolidone (NMP) offered finds wide use in chemical reactions especially in cases involving inert medium. Further, it also plays active role in reactions involving processes like oxidation, conversion involving chlorinating agents, condensation and other related reactions. Some of N-Methyl-2-Pyrrolidone (NMP) applications include for recovery of pure hydrocarbons in petrochemical processing through extractive distillation process, in desulfurization of gases present in natural/synthesis gases and in plastics, waxes, resins as solvent for handling natural and synthesis among others. We are one of the leading Importers & Suppliers of N-Methyl-2-Pyrrolidone (NMP) in India.

N-Methyl-2-Pyrrolidone (NMP) is used to recover certain hydrocarbons generated in the processing of petrochemicals, such as the recovery of 1,3-butadiene and acetylene. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization facilities. Due to its good solvency properties N-Methyl-2-Pyrrolidone (NMP) is used to dissolve a wide range of polymers. It is also used as a solvent for surface treatment of textiles, resins, and metal coated plastics or as a paint stripper. It is utilized as a solvent in the commercial preparation of polyphenylene sulfide. In the pharmaceutical industry, N-Methyl-2-Pyrrolidone (NMP) is used in the formulation for drugs by both oral and transdermal delivery routes. It is also used heavily in lithium ion battery fabrication, as a solvent for electrode preparation, though there is much effort to replace it with solvents of less environmental concern, like water.
