Patent

CA 2359072

Process for the preparation of amine-group-containing carboxylic acid salts by oxidation of amine-group-containing primary alcohols in an aqueous-alkaline reaction medium, in the presence of a copper catalyst, and at an elevated temperature, which is characterised in that the copper catalyst used is a reduced copper/chrome or copper/zinc spinel.

La présente invention concerne un processus de préparation de sels d'acides carboxyliques à groupes amine par oxydation d'alcools primaires à groupes amine dans un milieu réactionnel alcalin-aqueux, en présence d'un catalyseur de cuivre, à température élevée. Ce processus étant caractérisé en ce que le catalyseur de cuivre utilisé représente un spinelle cuivre/chrome ou cuivre/zinc réduit.
