Abstract
La présente invention est relative à un procédé de préparation d'acrylamide, caractérisé en ce qu'il consiste à traiter de l'acrylonitrile avec de l'eau, en présence d'un catalyseur à base de cuivre qui a été préparé en volatilisant du cuivre métallique, puis en refroidissant les vapeurs de cuivre en présence d'un solvant organique et en réchauffant à température ambiante, dans des conditions d'hydrolyse, et à récupérer l'acrylamide résultant.
