Abstract
Provided is a method for preparing a sucrose-6-ester, including: preparing a reaction solution of sucrose and an organo-tin compound; atomizing the reaction solution to form droplets; thoroughly mixing and contacting the droplets with a gasified dehydration medium such that the droplets undergo a dehydration reaction to obtain an intermediate mixture containing sucrose organic tin ester droplets; separating the intermediate mixture to obtain a sucrose organic tin ester solution and a dehydrated gas-liquid mixture; recovering the sucrose organic tin ester solution obtained in the separation step and cycling to the atomization and dehydration steps several times; and subjecting an organic acid anhydride to an acylation reaction with the sucrose organic tin ester solution to obtain the sucrose-6-ester.
