    Abstract:

    As a bio-based surfactant, sucrose ester has been widely used in food, medicine and cosmetics fields. At present, the synthesis of sucrose esters is mainly conducted by esterification, acyl chloride esterification and transesterification. And, the transesterification method is the most widely used method. However, the poor compatibility between sucrose and methyl esters leads to many side reactions, such as sucrose coking and agglomeration, methyl ester hydrolysis and saponification, which significantly affected the reaction efficiency and the product quality. In this work, the synthesis method of sucrose esters such as solvent method, microemulsion method and solvent-free method was introduced. Subsequently, this work introduced application of new catalytic technologies, such as phase transfer catalysts, solid base catalysts and ionic liquids. Physical interface strengthening technologies in the synthesis of sucrose esters was summarized. In the synthesis of sucrose esters, the design of solid base catalyst and application of multi-process coupling and strengthening technology and mechanism was prospected. Therefore, it can provide a technical support for future synthesis of sucrose ester surfactants.
