| titleOfInvention | A kind of method for preparing sucralose from sucrose-6-acetate and its subsequent purification |
| abstract | The invention discloses a method for preparing sucralose from sucrose-6-acetate and its subsequent purification. The sucrose-6-acetate is used for a high-temperature chlorination reaction, and the chlorination reaction is removed under reduced pressure after the chlorination reaction. The slurry obtained by the solvent is dissolved with an alcohol solvent to obtain material 1; material 1 and ammonia gas are passed into the first microchannel reactor together, and the reaction temperature is controlled to obtain material 2; material 2 and water are passed into the second Micro-channel reactor, control the reaction temperature to obtain material 3; material 3 is statically stratified to obtain material 3 organic solvent layer and material 3 water layer; material 4 obtained by extracting material 3 water layer with alcohol solvent is statically stratified The organic solvent layer of material 4 is obtained, and after being combined with the organic solvent layer of material 3, part of the solvent is removed by distillation under reduced pressure, and the sucralose is obtained by cooling and crystallizing. The invention greatly shortens the reaction time, improves the reaction efficiency, reduces the solvent consumption, and has the advantages of convenient operation, high product yield, less three wastes and the like. |
