Process for the preparation of n-substituted ª-pyrrolidones |
| abstract |
a -pyrrolidones, N-substituted by a monovalent organic radical, more particularly an alkyl or cycloalkyl radical, and optionally alkylated in the 3- and/or 4-positions, are prepared by heating succinic acid or an alkyl-succinic acid with a primary amine and hydrogen under superatmospheric pressure, in the presence of a hydrogenation catalyst. |
