| description | A method for at least partial deacetylation of a biopolymer comprising acetyl groups, comprising: a1 ) providing a biopolymer comprising acetyl groups; a2) reacting the biopolymer comprising acetyl groups with hydroxylamine (NH2OH) or a salt thereof at a temperature of 100 °C or less for 2-200 hours to form an at least partially deacetylated biopolymer; and a3) recovering the at least partially deacetylated biopolymer.
La présente invention concerne un procédé de désacétylation au moins partielle d'un biopolymère comprenant des groupes acétyle, comportant : a1) l'utilisation d'un biopolymère comprenant des groupes acétyle ; a2) la réaction du biopolymère comprenant des groupes acétyle avec de l'hydroxylamine (NH2OH) ou un sel de cette dernière à une température inférieure ou égale à 100 °C pendant 2 à 200 heures pour former un biopolymère au moins partiellement désacétylé ; et a3) la récupération du biopolymère au moins partiellement désacétylé. |
