The present invention relates to the technical field of sucrose-6-ester production, in particular to a scraper-type sucrose-6-ester continuous production equipment and production process, comprising: a tank, a mixing collection hopper, a molecular distillation device and a collection reaction device; Through the modification of the existing molecular distillation equipment, the invention enables all the reaction processes for the preparation of sucrose-6-ester to be completed within it at one time, shortening the connection time between the reaction process and upstream and downstream, and improving the production efficiency of sucrose-6-ester Greatly improved; at the same time, the sucrose solution is mixed with the organic tin acylation accelerator by the stirring mechanism in advance before the first reaction mixture is heated, and then the first reaction mixture is heated on the heating plate and reacts directly, at this time the heating plate At the same time, the heating required for the reaction of the first reaction mixture and the heating required for moisture removal are completed, so that the reaction heating and the molecular distillation heating share a heating plate, which saves a set of heating structures and saves energy consumption and cost.
Description
technical field [0001] The invention relates to the technical field of sucrose-6-ester production, in particular to a scraper-type sucrose-6-ester continuous production equipment and a production process flow. Background technique [0002] Sucralose, commonly known as sucralose, is an artificial sweetener with high sweetness, which can reach about 600 times (400-800 times) the sweetness of sucrose. Sucralose has no energy, high sweetness, pure sweetness, It has a high degree of safety and is one of the most ideal sweeteners at present. Sucrose-6-ester is a very important intermediate reactant in the production of sucralose. There are many synthetic routes, among which organotin-catalyzed synthesis is a relatively mature one. , the existing relatively mature organotin-catalyzed method for synthesizing sucrose-6-ester is: (a) stirring and mixing sucrose, a polar aprotic solvent, and an organotin acylation accelerator, and heating the organotin on the pole of the sucrose Tin r...
