Abstract: Described herein is a supported organotin catalyst and a preparation method for a sucrose-6-carboxylate. The supported organotin catalyst is prepared by coupling an organotin functional group to an inorganic carrier. The supported organotin catalyst of the present application can be used for catalyzing the generation of a sucrose-6-carboxylate, and after reaction, the supported organotin catalyst can be directly filtered and recovered only by adding a small amount of water to quench an acylating agent, so that the subsequent dehydration process is simpler and easier, and the supported organotin catalyst is thus very economical in terms of manpower, equipment and energy.
