ABSTRACT:
C.sub.1 -- to C.sub.6 -N-alkylpyrrolidones are produced from succinic anhydride and C.sub.1 -- to C.sub.6 -N-alkylamines or C.sub.1 -- to C.sub.6 --N-alkylsuccinimides. They are hydrogenated in the presence of a Ni hydrogenation catalyst containing from about 0.1-3% of one or several alkaline earth oxides and/or iron oxide and/or chromium oxide, at temperatures of from about 180.degree.-250.degree. C. and under pressures of at least about 100 bar. Preferably, a Ni catalyst is utilized which contains a total of 1.5-2% alkaline earth oxides, iron oxide and chromium oxide.
