GENERAL DESCRIPTION & EXTERNAL LINKS
|
|
Pyrrolidone is a keto-pyrrole, that is a 5-membered lactam structure compound (gamma-butyrolactam). Lactam structure compound including pyrrolidone has good solvency property, therefore useful in industrial application. It is an important part of antibiotics, such as penicillin. These structures, cyclic esters and analogues, are active nucleuses in pharmacological activity and flavorings. Lactams have big demand in artificial fibre industry. They are polymerizable and used as nylon precursors. 2-Pyrrolidone is used as a solvent for surface treatment for textiles, metal coated plastics, polymers, and paint removing. Pyrrolidone and its derivatives are used as Intermediates for the synthesis of agrochemicals, pharmaceuticals, textile auxiliaries, plasticizers, polymer solvent, stabilizers, specialty inks and as a nylon precursor. NMP is used as a solvent for paint stripping and resins; cleaner for polymeric residues; metal finishing; printed circuit board manufacturing; SBR latex production; pigment dispersant; extraction of acetylene and butadiene; dehydration of natural gas; lube oil processing;
