A process is proposed for the production of cyclic lactates by allowing aminocarboxylic acid nitriles to react with water in the presence of catalysts. The reaction takes place in the fluid phase in a fixed bed reactor in the presence of heterogeneous catalysts, no constituents of which are soluble under these reaction conditions.

L'invention concerne la production de lactames cycliques par réaction de nitriles d'acide aminocarboxylique avec de l'eau, en présence de catalyseurs. La réaction se fait en phase fluide dans un réacteur à lit fixe, en présence de catalyseurs hétérogènes qui ne comportent pas de constituants solubles dans les conditions de réaction.
