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.
- Contact cause severe irritation to eyes and skin.
- ThermoFisher: SDS
- EPA lists methylpyrrolidone as hazardous waste (ignitable, toxic); Concentrations over 10% must be disposed of appropriately
Physical and Chemical Properties
Miscible with water, alcohols, ether, acetone, ethyl acetate, chloroform, benzene and castor oil.
