Title:
POLYSACCHARIDE DERIVATIVE PRODUCTION METHOD AND LIGNIN DERIVATIVE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/184384
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polysaccharide derivative production method that does not require the use of a reagent such as an acid catalyst and is capable of smoothly carrying out a reaction without causing a side reaction.　A polysaccharide derivative production method according to the present invention is characterized by including a step in which a raw material, which contains a polysaccharide, is dissolved in at least one ionic liquid having an anion that is a non-carboxylic acid-based anion of which the conjugate acid in vacuum has a pKa of 4 or greater, and reacted with an acyl group donor.
