CA 2686470

Methods for depolymerizing polysaccharides are disclosed. In certain exemplary methods, polysaccharides having a first average molecular weight can be reacted with hydroxyl free radicals to produce polysaccharides having a second average molecular weight lower than the first average molecular weight. The hydroxyl free radicals can be formed by interaction of an oxidant with a catalyst comprising a polydentate ligand complexed with a metal ion. In certain exemplary embodiments, the oxidant can be hydrogen peroxide, and the catalyst can be iron methylglycine diacetate or iron-2,3,4,5,6 pentahydroxyhexanoate.

La présente invention concerne des procédés pour dépolymériser des polysaccharides. Dans certains procédés cités en exemples, des polysaccharides ayant un premier poids moléculaire moyen peuvent être mis en réaction avec des radicaux dépourvus de groupe hydroxyle pour produire des polysaccharides ayant un second poids moléculaire moyen, inférieur au premier. Les radicaux dépourvus de groupe hydroxyle peuvent être formés par interaction d'un oxydant avec un catalyseur comprenant un ligand polydenté complexé à un ion métallique. Dans certains modes de réalisation, l'oxydant peut être le peroxyde d'hydrogène, et le catalyseur, un 2,3,4,5,6- pentahydroxyhexanoate de fer.
