Procede d'esterification d'hydrates de carbone

Method for the esterification of carbohydrates

Werkwijze voor de verestering van koolhydraten

Abstract

Novel acylated, hydroxyalkylated carbohydrates are described which contain 0.5-2.0 acyl groups and 0.5-4.0 hydroxyalkyl groups on positions other than anomeric positions per monosaccharide unit. A process for the preparation thereof, in particular by enzymatic esterification of a hydroxyalkyl carbohydrate, in particular 2,3-dihydroxypropylsucrose or -lactose, is also described.
Cette invention décrit de nouveaux hydrates de carbone hydroxyalkylés acylés, qui contiennent 0,5 à 2,0 groupes acyle et 0,5 à 4,0 groupes hydroxyalkyle dans des positions autres que les positions anomères par unité monosaccharide. Un procédé pour préparer ces hydrates de carbone, en particulier par estérification enzymatique d'un hydrate de carbone hydroxyalkyle, tel que notamment du 2,3-dihydroxypropylsucrose ou -lactose est également présenté.
