The invention provides a method for preparing sucralose by continuously deacetylating sucralose-6-acetate. According to the method, in the presence of a basic catalyst, the sucralose-6-acetate is deacetylated to generate the sucralose, the catalyst is added in a segmented mode according to pH of a reaction solution, a novel reactor is adopted so that the catalyst can be rapidly mixed and dispersed, and the reaction temperature is easy to control. The synthetic sucralose has the advantages that residual quantity of the sucralose-6-acetate is small, the content of dichloro sucrose is low, the usage amount of the catalyst is small, the yield of the sucralose is high, continuous operation is achieved, the production cycle is shortened, and production cost is saved.
