Title:
METHOD FOR MANUFACTURING GLYCEROL CELLULOSE
Document Type and Number:
Japanese Patent JP2015227413
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing glycerol cellulose capable of manufacturing a solution high in soluble part to water and having high viscosity.SOLUTION: There is provided a method for manufacturing glycerol cellulose having a process of reacting raw material cellulose and glycidol in presence of a basic compound of over 0.6 mol equivalent and 1.4 mol equivalent or less per 1 mole of an anhydroglucose unit in the raw material cellulose in a solvent of 10 mass% to 200 mass% based on a cellulose part of the raw material cellulose to obtain glycerol cellulose mixture 1 having substitution degree of the glycerol group per the anhydroglucose unit of 0.2 or more and less than 1.5 (Process 1) and a process of mixing the glycerol cellulose mixture 1 with acid to adjust the amount of the basic compound at 0.1 mol equivalent to 0.6 mol equivalent per 1 mole of the anhydroglucose unit in the raw material cellulose and further adding glycidol and reacting to obtain glycerol cellulose having the substitution degree of the glycerol group per the anhydroglucose unit of 1.5 to 5.0 (Process 2).
