CARBOXY-FUNCTIONALIZED ALTERNAN

摘要

Functionalized alternan, comprising carboxy groups as functional groups, wherein the alternan can be described by the following formula (I) Alternan (I) wherein R1 is a hydrocarbon group with 1 to about 100 carbon atoms, optionally featuring one or more heteroatoms, wherein the oxygen between “Alternan” and R1 in Formula (I) is an oxygen of an ether group, as well as the procedures for producing such a functionalized alternan in a aqueous medium or using an alcohol or an alcohol-water mixture as a reaction medium, and the use of this functionalized alternan.;

1. Functionalized alternan polysaccharide, comprising carboxy groups as functional groups, wherein the alternan polysaccharide comprises structures of Formula (I): wherein R1 is a hydrocarbon group with 1 to about 100 carbon atoms, wherein said group can comprise one or more heteroatoms, and wherein the alternan can contain one or more of the —R1—COOH groups, and wherein one or more of the groups —R1—COOH can be deprotonated to —R1—COO−, andwherein the oxygen between “Alternan” and R1 in Formula (I) is an oxygen of an ether group.
