Title:
METHOD FOR PRODUCING POLYSACCHARIDE ESTER
Document Type and Number:
WIPO Patent Application WO/2020/245929
Kind Code:
A1
Abstract:
Provided is a method with which it is possible to industrially produce a polysaccharide ester with a high degree of efficiency. This method for producing a polysaccharide ester involves using a kneader equipped with a mechanism for imparting a shearing force to react a polysaccharide-containing biomass, a basic ionic liquid having a pKa of conjugate acid of anions calculated in a vacuum of 2-19, and an esterification agent. Cations that constitute the basic ionic liquid are preferably one type of cation selected from the group consisting of imidazolium cations, pyridinium cations and tetraalkylammonium cations.
