Patent

CA 2193034

he invention concerns a perfected process for alkaline oxidation in both an aqueous medium of sugars possessing one or more primary alcohol functions, using hypohalites, and in the presence of a catalyst composed of a binary or tertiary nitroxyl alkyl. The process is unusual in that oxidation occurs in the presence of high sugar concentrations. The products obtained through this process, some of which are new, can be used as builders in detergent compositions.

L'invention concerne un procédé perfectionné d'oxydation alcaline et en milieu aqueux de sucres possédant une ou plusieurs fonctions alcools primaires à l'aide d'hypohalites et en présence d'un catalyseur constitué par un nitroxyl alcyle binaire ou tertiaire. Le procédé est remarquable en ce que l'oxydation se déroule en présence de concentrations élevées de sucres. Les produits obtenus par le procédé, nouveaux pour certains d'entre eux, peuvent être utilisés comme builders dans les compositions lessivielles.
