发明名称 Process for making N-alkylpyrrolidones
摘要 An improved process for making N-alkylpyrrolidones from a maleic derivative or a succinic derivative which involves catalytically reducing the maleic derivative with hydrogen to succinic anhydride, if the maleic derivative is the starting point, converting succinic anhydride to a N-alkylsuccinimide by ammonolysis-alkylation with a C1 and C4 alkanol and ammonia, and catalytically reducing the resulting N-alkylsuccinimide to the N-alkylpyrrolidone.
