摘要:

以大豆油脂肪酸乙酯和蔗糖为原料,十六烷基三甲基溴化铵作相转移催化剂,采用两步法合成大豆油蔗糖多酯。采用响应曲面分析法中的Box-Behnken 模型对影响大豆油蔗糖多酯产率的4 个主要因素(反应温度、催化剂用量、酯糖物质的量比、反应时间)进行优化。优化出的最佳合成条件为反应温度135.6℃、催化剂用量4.1%、酯糖物质的量比13.5:1、反应时间5.5h。在此条件下,蔗糖多酯的产率达90.72%,酯化度达7.1。

Abstract:

Cetyltrim ethylammonium bromide was used as phase-transfer catalyst to synthesize soybean sucrose polyester from ethyl-esterfied soybean oil and sucrose by two-step method. Response surface analysis based on Box-Behnken experimental design was used to investigate the optimal values of reaction temperature, catalyst amount, ethyl-esterfied soybean oil/sucrose molar ratio and reaction time affecting soybean sucrose polyester yield. Results showed that under the following optimized conditions: reaction temperature 135.6 ℃, catalyst amount 4.1%, ethyl-esterfied soybean oil/sucrose molar ratio 13.5:1 and reaction time 5.5 h, the soybean sucrose polyester yield and the esterfication degree were up to 90.72% and 7.1, respectively.

Key words: sucrose, ethyl ester, soybean oil sucrose polyester, phase-transfer catalyst, response surface methodology
