Beschreibung
Zusammenfassung:	Provided are a supported catalyst and a method for synthesizing a sucrose-6-ester, wherein the supported catalyst is used for catalyzing a transesterification reaction between sucrose and carboxylate. The supported catalyst includes an active functional component and an inorganic carrier, wherein the active functional component is a compound shown in formula (1), wherein n is a natural number greater than or equal to 2; R is an atom linked to a surface of the inorganic carrier; and one or two of R1, R2, and R3 is/are hydrocarbyl, and the rest are independently any one selected from the group consisting of oxygen, hydroxyl, hydrocarbyloxy, and acetoxy. In the present disclosure, the supported catalyst can highly selectively catalyze the transesterification reaction between sucrose and a low-alcohol carboxylate to obtain a sucrose-6-ester. After the reaction is completed, the supported catalyst can be recovered by filtration without almost no loss, which avoids the use of the controlled substance carboxylic anhydride.
