Abstract

The utility model discloses a special hydrolytic equipment and uses in the continuous synthesis acesulfame-k process without an agitated device. The equipment consists of a hydrolytic reaction kettle, a feed inlet on the side wall of the reaction kettle, a feed back mouth, an out-feed inlet on the bottom of the reaction kettle. The outlet of the ejector pump is communicated with the feed inlet. The feed back mouth is communicated with the water source via pipes, and then communicated with an inlet of the recycle pump. The other inlet of the recycle pump accesses to the residue of sulfonation reaction. In the synthesis acesulfame-k process, the utility model meets the requirement of continuous production and improves the efficiency greatly.

Description

Hydrolysis process specialized apparatus in a kind of synthesis of acetyl sulfanilic acid potassium process
Technical field
The utility model relates to hydrolysis process specialized apparatus in the synthesis of acetyl sulfanilic acid potassium process.
Background technology
Acesulfame potassium is a kind of sweeting agent that is widely used in food, beverage industry.This compound has good water solubility, sugariness height, advantages such as physico-chemical property is stable, synergism is strong, non-metabolic.
The method of synthesis of acetyl sulfanilic acid potassium is a lot.It is US4 that the synthetic method of the acesulfame potassium that the utility model is involved is based on the patent No.; 695; 629 United States Patent (USP); its main method step is as follows: with thionamic acid is that a kind of raw material reacts with ketene dimer under the catalysis of triethylamine; use SO 3 sulfonated cyclization then; make acesulfame through hydrolysis again, make acesulfame potassium with the potassium hydroxide reaction again.Making a general survey of with the sulphur trioxide is other relevant patent of sulphonating agent synthesis of acetyl sulfanilic acid potassium---as: the patent No. is US4,695,629 and US5,011,982 and US5,103,046, also do not find the special reaction equipment that SO 3 sulfonated cyclization is relevant with hydrolysis, the reaction that is hydrolyzed the time all be usually material dropping that sulphonation ring closure has been reacted in reactor, simultaneously water also is added drop-wise to the reaction that is hydrolyzed in the reactor, on reactor, generally also be provided with whipping appts to promote reaction process, in addition, also must feed refrigerated brine in the chuck of reactor in reaction, sulphur trioxide and water react rapid liberated heat during with the cooling hydrolysis; But the dilute sulphuric acid that forms when reaction has very strong corrodibility and oxidisability, can produce corrosion to whipping appts and sealing member, and leakage accident takes place.In addition, this hydrolysis reaction device and the mode of production thereof can not realize serialization production, and can only be discontinuity production, and efficient is lower.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of can serialization production and do not need hydrolysis process specialized apparatus in the synthesis of acetyl sulfanilic acid potassium process of whipping appts.
For solving the problems of the technologies described above, the concrete technical scheme that the utility model adopts is: the specific equipment of described hydrolysis process, comprise: hydrolytic reaction pot, the sidewall of hydrolytic reaction pot is provided with opening for feed, feedback outlet, the bottom of hydrolytic reaction pot is provided with discharge port, opening for feed is connected with the injection pump outlet, feedback outlet by pipeline be connected with inlet of circulating pump again after the water source is connected, outlet of circulating pump is connected with the import of condenser, the outlet of condenser is connected with an import of squirt pump, and another import of squirt pump is connected with the material that sulfonation reaction is finished.
Above-mentioned opening for feed is separately positioned on the sidewall relative on the hydrolytic reaction pot with feedback outlet.
The utility model has the advantages that: use specific equipment described in the utility model in the hydrolysis reaction technology in synthesis of acetyl sulfanilic acid potassium process, not only equipment is simple, need not whipping appts, and can realize serialization production, has improved production efficiency greatly.
Description of drawings
Fig. 1 is the structure principle chart of the specific equipment of hydrolysis process described in the utility model.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the specific equipment of described hydrolysis process comprises: hydrolytic reaction pot 10, on the relative sidewall of hydrolytic reaction pot 10, be respectively arranged with opening for feed 11, feedback outlet 8, the bottom of hydrolytic reaction pot 10 is provided with discharge port 9, opening for feed 11 is connected with the outlet 5 of squirt pump 4, feedback outlet 8 by pipeline be connected with the import of recycle pump 6 again after water source 7 is connected, the outlet of recycle pump 6 is connected with the import of condenser 12, the outlet of condenser 12 is connected with an import 1 of squirt pump 4, and another import 2 of squirt pump 4 is connected with the material 3 that sulfonation reaction is finished.
Utilize the be hydrolyzed detailed step of technology of above-mentioned specific equipment as follows: the material 3 that sulphonation ring closure has been reacted is incorporated into an input aperture 2 of squirt pump 4, by squirt pump 4 the direct high-velocity jet of material is entered into hydrolytic reaction pot 10 reaction that is hydrolyzed; Simultaneously, with recycle pump 6 the partial reaction material in the hydrolytic reaction pot 10 is sent in the condenser 12 with water and cools off, can preferably be controlled at-10 ℃~15 ℃ through condenser 12 cooled material temperature, to be incorporated into another input terminus 1 of squirt pump 4 through condenser 12 cooled materials again, and enter into hydrolytic reaction pot 10 by squirt pump 4 high-velocity jet with the material that sulphonation ring closure has reacted; And the material after the hydrolysis reaction end is drawn from the bottom discharge mouth 9 of hydrolytic reaction pot 10.
From the above mentioned as can be known, squirt pump 4 can form negative pressure when high-velocity jet, help material 3 that sulphonation ring closure has been reacted more and suck and be ejected in the hydrolytic reaction pot 10, they just need not be stirred in hydrolytic reaction pot 10 can carry out sufficient hydrolysis reaction through condenser 12 cooled materials; In addition, in reaction process, partial material is incorporated in the condenser 12 of hydrolytic reaction pot 10 outsides and cools off, help controlling the temperature of reactant more; Therefore, use hydrolysis process described in the utility model and specific equipment thereof, just can realize serialization production, improved production efficiency greatly.
