Procedure

An aqueous solution of maleic anhydride and methylamine (20 wt % of maleic anhydride/methylamine, molar ratio 1:1.5) was hydrogenated over a cobalt catalyst at 250° C. and 250 bar. Following subsequent purification, by distillation, of the hydrogenation product stream there were obtained 71% of N-methylpyrrolidone, 5% of N-methylpyrrolidine, and 6% of succinic acid-N-methylimide. There remained 17% of residue (calculated as succinic acid-N-methylamide).
