1-Methyl-2-pyrrolidinone Chemical Properties
Chemical Properties l-Methyl-2-pyrrolidone can undergo a number of chemical reactions even though it is accepted as a stable solvent. It is resistant to hydrolysis under neutral conditions, but strong acid or base treatment results in ring opening to 4-methyl aminobutyric acid. l-Methyl-2-pyrrolidone can be reduced to 1-methyl pyrrolidine with borohydride. Treatment with chlorinating agents results in amide formation,an intermediate which can undergo further substitution, while treatment with amyl nitrate yields the nitrate. Olefins can be added to the 3 position by treatment first with oxalic esters, then with appropriate aldehyes (Hort and Anderson 1982).
Chemical Properties colourless or light yellow liquid with an amine odour
Uses It is a versatile industrial solvent. NMP is currently approved for use only in veterinary pharmaceuticals. The determination of the disposition and metabolism of NMP in the rat will contribute toward understanding the toxicology of this exogenous chemical which man may likely be exposed to in increasing amounts.

Raw materials Acetone-->METHYLAMINE-->gamma-Butyrolactone-->Butyramide
N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide. It is used in the petrochemical and plastics industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials.
