Synthesis and Surface Properties of Maltitol Dodecenyl Succinate
摘要
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 h at 35 ℃ and a maltitol-to-anhydride molar ratio of 2：1.Infrared spectral and mass spectrometric analyses revealed that the surface tension of 1 mg/mL aqueous solution of the synthesized maltitol dodecenyl succinate was 31.9 × 10^-3 N/m,the foaming capacity 50%,the emulsification capacity 100% and the HLB 15.1.关键词
