実験手順

U.S. Application No. 4,731,454 describes the preparation of N-methylpyrrolidone (NMP) by hydrogenating N-methylsuccinimide on a cobalt/rhenium/molybdenum catalyst. U.S. Application No. 3,109,005 discloses a process for the preparation of NMP by hydrogenating maleic anhydride (MAA)/methylamine mixtures on a Raney nickel catalyst. At reaction times of 10 hours, NMP yields of 70% are achieved in this process. According to the process of DE-A 22 00 600, NMP is obtained in a yield of 44% under the most favorable conditions by hydrogenating MAA/methylamine mixtures on palladium supported catalysts.
