| 摘 要： | 以稀氢氧化钠溶液(30mg/mL)为催化剂，以麦芽糖醇和十二烯基琥珀酸酐为原料合成了十二烯基琥珀酸单麦芽糖醇酯。通过考察原料配比、酸酐溶剂种类、酸酐滴加时间、反应时间4种因素对十二烯基琥珀酸单麦芽糖醇酯产率的影响，确定了最佳反应条件：麦芽糖醇与十二烯基琥珀酸酐物质的量比为2:1，酸酐溶剂为丙酮，酸酐滴加时间1.5h，在35℃条件下反应5h，十二烯基琥珀酸单麦芽糖醇酯的产率为89.7%。利用红外光谱和质谱分析方法对合成产品进行表征，并对其表面性质进行测定。当合成产品的质量浓度为1mg/mL时，表面张力为31.9×10-3N/m，起泡能力为50%，乳化能力为100%，亲水亲油平衡值(HLB)为15.1。

| Abstract: | The dilute sodium hydroxide-catalyzed synthesis of maltitol dodecenyl succinate from maltitol and dodecenly succinic anhydride was investigated with respect to anhydride solvents,drop-by-by addition rate of anhydride,reaction time and maltitol-to-anhydride molar ratio.The maximum product yield of 89.7% was obtained under the optimal reaction conditions: acetone was used to solve dodecenyl succinate;the time required to complete anhydride addition drop by drop was 1.5 h;and the whole reaction duration was 5 ... |
