Title:
ONIUM SALT, ONIUM SALT COMPOSITION, LIQUID COMPOSITION CONTAINING ONIUM SALT AND POLYSACCHARIDE AND PRODUCTION METHOD THEREOF, AND METHOD FOR RECOVERING POLYSACCHARIDE
Document Type and Number:
WIPO Patent Application WO/2023/189817
Kind Code:
A1
Abstract:
The present invention relates to an onium salt, a liquid composition containing the onium salt and a polysaccharide, and a method for recovering a polysaccharide. The invention can provide an onium salt that has a very high polysaccharide solubility at temperatures of 10-50°C, in particular, around room temperature (25°C). Also, the invention can provide a liquid composition containing the aforesaid onium salt and a polysaccharide, as a composition suitable for recovering the polysaccharide, and a method for efficiently recovering a polysaccharide with the use of such a liquid composition containing an onium salt and the polysaccharide.
