    • A process for the preparation of an alkoxylated sucrose ester including the steps of: forming an initial reaction mixture of a sucrose ester and from about 0.01% to about 5% of a catalyst; and forming an initial reaction product by reacting the initial reaction mixture with an epoxide for a period of time in the range of from about 30 minutes to about 6 hours and at a temperature in the range of from about 80° C. to about 120° C.; wherein the epoxide and the sucrose ester are selected such that a mole ratio of epoxide groups to sucrose hydroxyls is from about 1 to about 100. Useful catalysts include sodium metals, potassium metals, sodium/potassium alloys, and mixtures thereof
    • 一种制备烷氧基化蔗糖酯的方法,包括以下步骤:形成蔗糖酯和约0.01%至约5%催化剂的初始反应混合物; 并通过使初始反应混合物与环氧化物反应约30分钟至约6小时,并且在约80℃至约120℃的温度下反应形成初始反应产物 C。; 其中选择环氧化物和蔗糖酯使得环氧基团与蔗糖羟基的摩尔比为约1至约100.可用的催化剂包括钠金属,金属钾,钠/钾合金及其混合物
