Problems solved by technology
This method requires the use of gas or solvent vapor that can remove water. The existence of this link seriously affects the continuity of the production process of synthetic sucrose-6-ester, increases the production time, and reduces the production efficiency. Therefore, a special set is required. The equipment and production method for the production of sucrose-6-ester, overcome the disadvantage of using gas or solvent vapor capable of removing water to remove water in the process of removing water from the first reaction mixture, and overcome the need to inject the second reaction mixture at the same time The time it takes to mix with carboxylic anhydride in another space

The invention relates to the technical field of evaporation devices for organic materials, in particular to sucrose 6 ester processing equipment and methods thereof, including: a tank body, a film scraper, a condensing device, a cooling device, a discharge pipe, a motor, a feed pipe, and a carboxylic anhydride feeder. material pipe, vacuum pipe, drain pipe; the outer wall of the tank is provided with a heating element, and the heating element is used to conduct heat to the wall of the tank; the wiper is connected inside the tank and is on the same line as the axis of the tank; The scraper performs scraped-film distillation on the first reaction mixture to remove moisture to form the second reaction mixture, and then the second reaction mixture moves upward in the form of a film to cool down through the cooling device, and finally the second reaction mixture in the rotating discharge pipe goes downward Mixing with downward flowing carboxylic acid anhydride to form sucrose 6 ester, the process of the present invention can be completed continuously from distillation to cooling and then to mixing, with high efficiency and simple equipment structure.
Description
technical field [0001] The invention relates to the technical field of evaporation devices for organic materials, in particular to sucrose 6 ester processing equipment and methods thereof. Background technique [0002] A method for synthesizing sucrose-6-ester, comprising: mixing sucrose, an aprotic polar solvent and an organic tin acylation accelerator to form a first reaction mixture; then mixing the first reaction mixture with the A gas or solvent vapor capable of removing water is contacted and kept for a certain reaction time, and water is removed therefrom to obtain a second reaction mixture; then, carboxylic anhydride is added to the second reactant to obtain a third reaction mixture, and the third reaction mixture is kept enough Time to prepare sucrose-6-ester. This method requires the use of gas or solvent vapor that can remove water. The existence of this link seriously affects the continuity of the production process of synthetic sucrose-6-ester, increases the pr...
