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
