| Abstract: | Diethylene glycol monoallyl ether glucoside was prepared by reacting diethylene glycol monoallyl ether with glucose in the presence of p-toluenesulfonic acid catalyst.The effects of reactants ratio,reaction time,reaction temperature and catalyst dosage on the degree of polymerization were studied.The average degree of polymerization of diethylene glycol monoallyl ether glucoside was 1.06 under the conditions of n(glucose) ∶n(diethylene glycol monoallyl ether)=1∶4,catalyst dosage of 3.2%(based on glucose),reaction temperature of 110 ℃,and reaction time of 5 h. |
