Title:
SUPPORTED CATALYST AND SYNTHESIS METHOD FOR SUCROSE-6-ESTER
Document Type and Number:
WIPO Patent Application WO/2022/198478
Kind Code:
A1
Abstract:
Provided are a supported catalyst and a synthesis method for sucrose-6-ester. The supported catalyst is used for catalyzing a transesterification reaction of sucrose and a carboxylic ester. The catalyst comprises an active functional component and an inorganic carrier, wherein the active functional component is a compound represented by formula (1), wherein n is a natural number greater than or equal to 2; R is an atom connected to the surface of the inorganic carrier; one or two of R1, R2 and R3 are a hydrocarbyl, and the rest are respectively and independently selected from any one of an oxygen atom, hydroxyl, hydrocarbyloxy and acetoxy. The catalyst of the present application can catalyze a transesterification reaction of sucrose and an ester of a carboxylic acid and a lower alcohol with a high selectivity to obtain sucrose-6-ester. The catalyst can be recovered by means of filtration after the reaction and has little loss, and the use of a restricted article, i.e. a carboxylic acid anhydride, is avoided.
