Double-scraper type sucrose-6-ester continuous production equipment and production process flow

Abstract

The invention relates to the field of sucrose-6-ester production, in particular to double-scraper type sucrose-6-ester continuous production equipment and a production process flow, and the double-scraper type sucrose-6-ester continuous production equipment comprises a tank body, a liquid separation distillation device, a condensation collection device, a mixed reaction device, a motor I and a motor II. A stirring cavity is formed in the lower portion of a liquid separation conical disc for stirring and mixing, space resources on the lower portion of the liquid separation conical disc are fully utilized, the size of the whole equipment is greatly reduced, and therefore the equipment cost is reduced; reactive distillation can be performed on the inner surface and the outer surface of a heating plate, and surface resources of the heating plate are fully utilized, so that two sets of molecular distillation can be simultaneously realized by one heating plate, the production efficiency is improved, the structure is simplified, and the cost is reduced; the mixed reaction device adopts convective mixing, the mixing effect is better, a scraper film forming mode is adopted, a thin mixed liquid film can react rapidly, the second reaction is faster, and the efficiency is higher.

Description

technical field [0001] The invention relates to the field of sucrose-6-ester production, in particular to a double-scraper type continuous production equipment and production process for sucrose-6-ester. 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 reactio...
