Description
Technical field
The utility model relates to a kind of continuous preparation cane sugar-6-acetic ester ordered structure reactor.
Background technology
Cane sugar-6-acetic ester is the intermediate of synthesizing trichloro, and existing preparation cane sugar-6-acetic ester all is to adopt the discontinuous method preparation in reactor or electrolytic cell.Because the concentration of sucrose in solution is generally 10-20%, so the acquisition product very in a small amount that very big consersion unit can only be intermittently, utilization rate of equipment and installations is very low, and the production time is longer.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of utilization rate of equipment and installations height, production time to shorten and be applicable to the ordered structure reactor of continuous preparation cane sugar-6-acetic ester, solved the problem that above-mentioned prior art exists.
The technical scheme that solves the problems of the technologies described above is: a kind of continuous preparation cane sugar-6-acetic ester ordered structure reactor, this reactor comprises that its outer setting has the reactor shell of insulation jacket, upper cover, low head, have the card of through hole on strip ordered structure catalyst and its, the reactor shell two ends are connected with low head with upper cover respectively by adpting flange, the ordered structure catalyst two ends are separately fixed on the card, card is installed in the reactor shell, have the reactant liquor inlet on the low head, have the reactant liquor outlet on the upper cover, the insulation jacket bottom is provided with the conduction oil inlet, and insulation jacket top is provided with the conduction oil outlet.
Described ordered structure catalyst shape of cross section is the dodecagon of hollow, and its inner rim is shaped as circle, and outer rim is shaped as the dodecagon that straight flange and circular arc limit are connected at interval.
Owing to adopt said structure, a kind of continuous preparation cane sugar-6-acetic ester ordered structure reactor of the utility model, have following beneficial effect: the utility model has the function of catalyst and reactor concurrently, can improve activity of such catalysts and selectivity, the mass-transfer efficiency height, have lower pressure and fall, help the serialization industrial production, become very easy from the laboratory to industrialized amplification process; The utility model at first prepares ordered structure catalyst, ordered structure catalyst placed make the ordered structure reactor in the reactor shell, the sucrose solution that contains ethyl acetate Continuous Flow is at a certain temperature crossed the ordered structure reactor, acquisition cane sugar-6-acetic ester that can be directly continuous, adopt the utility model the Batch Process of cane sugar-6-acetic ester can be improved to continuous production, improve utilization rate of equipment and installations, shorten the production time.
Below, in conjunction with the accompanying drawings and embodiments a kind of continuous preparation cane sugar-6-acetic ester of the utility model technical characterictic with the ordered structure reactor is further described.
