APPLICATIONS |
||
| 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; | ||

GENERAL DESCRIPTION OF LACTONE |
||
|
Lactone is an internal cyclic monoester (anhydride) derived from the hydroxyl and carboxyl radicals of gamma or delta hydroxy acids by the removal of a H2O between a carboxyl and a hydroxyl group in the same molecule; gamma-hydroxybutyric acid forms gamma-butyrolactone and delta-hydroxydecanoic acid forms delta-decalactone spontaneously. In result, prefixes describe the ring size: beta- is for 4-membered ring), gamma- , 5-membered, and delta-, 6-membered ring. Lactam (a cyclic amide) is the nitrogen analog of lactone. Gamma-aminobutyric acid forms gamma-butyrolactam (also called 2-pyrrolidinone). Lactim is the tautomeric enol form of lactam. Lactam structure, a heteroatomic cyclic amide compound, is an important part in antibiotics such as penicillin. These structures, cyclic esters and analogues, are active nucleuses in pharmacological activity and flavorings. Their good solvency properties also useful in industrial application. Lactams have big demand in artificial fibre industry. They are polymerizable and used as nylon precursors. |
