Description
A colorless liquid with a mild, amine-like odor. Methylpyrrolidone, or MP, is industrially as a
Solvent for the extraction of aromatic compounds from lubrication oils. It also dissolves many
polymers and old
varnishes.
Synonyms and Related Terms
methyl pyrrolidone; 1-methyl-2-pyrrolidinone; n-methyl-2-pyrrolidone; n-methyl-2-butyrolactone; NMP; MP; M-Pyrol
Risks
- Combustible. Flash point = 96C
- Decomposes on burning to produce toxic fumes including nitrogen oxides and carbon monoxide.
