| Abstract: | Glucoseate was synthesized using TiGeW_(12)O_(40)/TiO_2 as catlyst ,and glucose, stearate,glucol,dodecane sodium sulfate as raw material.Effects of the amount of the catalyst used,the reaction time,the ration of reactants and amount of the agent were investigated.As the experiment indicated that TiGeW_(12)O_(40)/TiO_2 is a good catalyst,and the optimum conditions were as follows:the ration of glucose and acid is 1:1.2,the amount of catalyst is 2%,and the reaction time 1.5 h.The eaterification ratio of glucoseate was 92.4%. |
