TiGeW_(12)O_(40)/TiO_2催化剂微乳化合成葡萄糖酯 |
梁英(襄樊学院化学与生物科学系; 湖北襄樊) |
摘 要:以固载杂多酸 TiGeW12 O40/TiO2 为多相催化剂,对以葡萄糖、硬脂酸、1,2-丙二醇、十二烷基硫酸钠等为原料合成葡萄糖酯的微乳化反应条件进行了研究。实验表明,TiGeW12O40/TiO2 是合成葡萄糖酯的良好催化剂,优化反应条件是:n(糖)∶n(酸)=1∶1.2 ,催化剂用量为反应物总量的2%,反应时间为1.5 h,葡萄糖硬脂酸酯的收率是92.4%。 |

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 gl... |
