A belt type sucrose 6 ester synthesis equipment

Abstract

The invention discloses a belt-type sucrose 6-ester synthesis equipment, which comprises a tank body. The inside of the tank body is provided with a condensation mechanism, a heating mechanism, a heat insulation mechanism, a rotating device and a motor. The condensation mechanism includes a condensation plate. The heating mechanism includes a heating plate, the heat insulation mechanism includes a heat insulation plate, and a rotating stirring mechanism is arranged inside the tank body, and the rotating stirring mechanism includes a rotating device and a motor. The invention solves the problem that the production process of sucrose-6-ester is long and the production efficiency is low.

Description

technical field

[0001] The invention relates to the field of evaporation of organic matter, in particular to a belt type sucrose 6 ester synthesis equipment. Background technique

[0002] Sucrose-6-ester is an important intermediate in the synthesis of artificial sweetener sucralose. The method for synthesizing sucrose-6-ester in current technology includes: mixing sucrose, aprotic polar solvent and organic tin acylation accelerator into a first reaction mixture; then the first reaction mixture is contacted with a gas or solvent vapor capable of removing water at a specific temperature and pressure environment and maintained for a certain reaction time, from which water is removed to obtain a second reaction mixture; then to the second reaction Carboxylic anhydride is added to the mixture to obtain a third reaction mixture, and the third reaction mixture is maintained for a time sufficient to prepare sucrose-6-ester.

[0003] In the whole process, the first mixture removes ...

Embodiment 1

[0031] like Figure 1-3 As shown, the tank body 1 includes: a vacuum pumping pipe 11, a liquid inlet pipe 12, a guide plate 13, a liquid outlet 14, a feed pipe 15, a guide plate 2 16, and a discharge port 17;

[0032] The overall shape of the tank body 1 is square, and its upper end is provided with a vacuum exhaust pipe 11, so that the inside of the tank body is in a vacuum state, which is conducive to the evaporation of the first mixed liquid;

[0033] The liquid inlet pipe 12 is arranged on the wall surface of the tank body 1 close to the vacuum pumping pipe 11, and it is arranged obliquely downward along the wall surface of the tank body 1. When the first mixed liquid flows into the tank body 1 from the liquid inlet pipe 12, it is The lower power falls on the heating plate 4 and the rotating device 5;

[0034] The side of the tank body 1 is provided with a condensing plate-21, which is square in shape and fits with the inner wall of the tank body 1, and a guide plate-13 i...
