Summary:The invention relates to a method for synthesizing high-purity sucrose monoester, which comprises the following steps of: ball-milling and uniformly mixing sucrose, higher fatty acid ester, higher fatty acid salt and a catalyst to obtain a mixture, preheating the ball-milled mixture in vacuum, and heating and stirring in an induction furnace to obtain a crude product; adding warm water into the crude product while hot, stirring, neutralizing with acetic acid, adding a calcium chloride solution, filtering and precipitating to obtain a mixed solution; carrying out ultrasonic oscillation on the mixed solution, standing for layering, and separating to obtain an aqueous solution and an organic solution; placing the organic liquid in ice water in a water bath to separate out white crystals, filtering, and drying under reduced pressure to obtain a product A; placing the aqueous solution in ice water for water bath, adding a sodium chloride solution for recrystallization, removing a lower-layer aqueous phase, and dry
