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;
