Title (EN) METHOD FOR OBTAINING MODIFIED POLYSACCHARIDES BY OXIDATION OF HYDROXYL GROUPS
(FR) PROCEDE POUR L'OBTENTION DE POLYSACCHARIDES MODIFIES PAR OXYDATION DES GROUPES HYDROXYLES
Abstract: front page image
(EN)The invention concerns a method for obtaining modified polysaccharides by oxidation of hydroxyl groups, which consists in subjecting the polysaccharide to the action of a peroxide in the presence of at least a phtalocyanine-metal complex serving as catalyst, the metal being selected among Fe, Co, Mn, Ni, V and Ru. The peroxide is selected among alkali metal or alkaline-earth metal percarbonates and perborates, alkyl peroxides, paracetic acid and hydrogen peroxide.
(FR)L'invention concerne un procédé pour l'obtention de polysaccharides modifiés par oxydation des groupes hydroxyles.Le procédé consiste à soumettre le polysaccharide à l'action d'un peroxyde en présence d'au moins un complexe phtalocyanine-métal agissant comme catalyseur, le métal étant choisi parmi Fe, Co, Mn, Ni, V et Ru. Le peroxyde est choisi parmi les percarbonates et les perborates de métal alcalin ou de métal alcalino-terreux, les peroxydes d'alkyle, l'acide peracétique et le peroxyde d'hydrogène.
