摘要：

Alkyl glycosides were synthesised from starch and alcohols using Aspergillus oryzae alpha-amylase as catalyst. The surface plot of objective function is drawn by Minitab in order to more directly reflect the interaction between the various factors that affect the sugar conversion rate and the role of strength for interaction between the various experimental factors. The result shows that in the reaction with methanol, methyl maltoside and methyl maltotrioside were the main alcoholysis products. It is seen that there is strong interaction among the various experimental factors. When catalyst mass concentration is 10%, reaction time is 1 h, reaction ratio is 1, sugar conversion rate is 98.80%. Response surface methodology (RSM) could be effectively adopted to optimize the operating multifactor in synthesis of alkyl glycosides nonionic surfactant process.
