摘要
Abstract
Cellulose and so on biological resources can be extracted from soy sauce residues, because of poor solubility in regular solvent,cellulose was generally discarded.However,ionic liquids show higher solubility of cellulose, which can be used as good solvents for cellulose derivatization.In this work,soy sauce residues which has had been extracted of fatty acids and hemicelluloses was used as raw material to further extraction of cellulose,then the synthesis of cellulose benzoates by homogeneous benzoylation of cellulose with ionic liquids used as reaction medium was studied.This study focused on investigating the effects of the kinds of ionic liquids on the productivity and DS of (degree of substation)cellulose benzoates,and the effects of reaction temperature,reaction time and the mole ratio of benzoyl chloride to cellulose glucose on the DS of cellulose benzoates.It is observed that homogeneous benzoylation of cellulose in ionic liquid AmimCl has best productivity,and when reaction temperature was 80℃,reaction time was 90min and the molar ratio of benzoyl chloride to cellulose glucose unit was 4∶1,had the highest DS of cellulose benzoates of 0.72.关键词
