Application 1-Methyl-2-pyrrolidinone may be used as a solvent in the following processes: Preparation of 2-aryl and 2-alkyl benzothiazoles. Ullmann coupling reaction of aryl halides and phenols to form Ullmann ethers in the presence of 2,2,6,6-tetramethylheptane-3,5-dione.

How is NMP /N-methyl-2-pyrrolidone made?

Large-scale production of NMP /N-methyl-2-pyrrolidone/ is predominantly carried out by reacting gamma-butyrolactone with an excess of pure or aqueous methylamine in a high-pressure tube reactor (6-12 MPa). The reaction is exothermic and often run under adiabatic conditions with reactor temperatures in the range of 250-400 °C.
