Rotary sucrose-6-ester continuous production equipment and production method

Abstract

The invention relates to the technical field of sucrose-6-ester production, in particular to rotary sucrose-6-ester continuous production equipment and a production method. The production equipment comprises a tank body, a cooling body, a conical heating disc, a spraying pipe, a stirrer, a liquid collecting disc, a small gear, a large gear and a driving motor, and the tank body is formed by connecting a lower tank cover, a main tank and an upper tank cover. The upper tank cover can be detached during installation or detachment to facilitate installation and maintenance, the driving motor is fixedly installed on the lower end face of the lower tank cover, the small gear is fixedly installed on the driving motor, a vacuum pipe is fixedly installed on the circumference of the main tank, a cooling body is fixedly installed in the main tank, and the whole cooling body is of a shell structure. The molecular distillation equipment is modified, so that all reaction processes for preparing the sucrose-6-ester can be completed in the molecular distillation equipment at one time, the reaction processes and upstream and downstream connection time are shortened, and the production efficiency of the sucrose-6-ester is greatly improved.

Description

Technical field [0001] The present invention relates to the field of sucrose-6-ester production, and more particularly to a rotary sucrose-6-ester continuous production equipment and a production method. Background technique [0002] Trichlorosae is known as sucrose, is a highly sweet artificial sweetener, which can achieve a sweetness of sucrose is about 600 times (400 ~ 800 times), and Trichlorosa has no energy, high sweet, pure sweet, High security, is one of the most ideal sweeteners, sucrose-6-ester is a very important intermediate reactant for producing diplocelasia, with a variety of synthetic paths, wherein organom tin catalytic synthesis is a relatively mature The method of the existing mature organotin-catalyzed synthetic sucrose-6-ester is: (a) stir mixing sucrose, polar aprotic solvent, and organic tin acylated promoters and mixed and heating, and organic tin in sucrose Non-proton solvent (DMF) solution, tinning reaction with sucrose: sucrose + organic tin → organic t...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the present invention is just made in view of the above problems. The purpose of the present invention is to make all reaction processes in this equipment disposable and shorten the process of the whole sucrose-6-ester by transforming the molecular distillation equipment. Production process, each flow process time etc., improve production efficiency, to solve the problem that existing production technology flow process is many, production efficiency is low, the present invention realizes above-mentioned purpose by following technical scheme:
