Description
Technical field
The utility model relates to the sulphonation ring closure technology specialized apparatus in a kind of 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, carry out the sulphonation ring closure reaction and the time all be usually sulfonation reaction raw material and sulphonating agent be added drop-wise to and carry out the sulphonation ring closure reaction in the reactor, on reactor, generally also be provided with whipping appts to promote reaction process, in addition, in reaction, also must in the chuck of reactor, feed refrigerated brine, liberated heat during with the cooling reaction, control reaction temperature; After deliberation, sulphur trioxide is a kind of highly corrosive agents, oxygenant, smoke substance, finishes this step sulphonation ring closure reaction with common conversion unit, causes the leakage of sulphur trioxide easily, and especially mechanical seal part is easy to leak owing to stir wearing and tearing.Sulphur trioxide is the chemical of danger close, and its leakage brings great negative impact can for production and environment.In addition, this sulfonation 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 sulphonation ring closure technology 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 sulphonation ring closure technology, comprise: reactor, the sidewall of reactor is provided with opening for feed, feedback outlet, the bottom of reactor is provided with discharge port, and the position of opening for feed is lower than the position of feedback outlet, opening for feed is connected with the injection pump outlet, feedback outlet is connected with inlet of circulating pump, outlet of circulating pump is connected with the import of condenser, the outlet of condenser is connected with an input terminus of squirt pump, and two input terminuss in addition of squirt pump are connected with sulfonation reaction raw material and sulphonating agent respectively.
The utility model has the advantages that: use specific equipment described in the utility model in the sulphonation ring closure technology in synthesis of acetyl sulfanilic acid potassium process; not only technology and equipment are simple; need not whipping appts, and can realize serialization production, improved production efficiency greatly.
Description of drawings
Fig. 1 is the structure principle chart of the specific equipment of sulphonation ring closure technology 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 sulphonation ring closure technology comprises: reactor 1, the sidewall of reactor 1 is provided with opening for feed 10, feedback outlet 8, the bottom of reactor 1 is provided with discharge port 11, and the position of opening for feed 10 is a little less than the position of feedback outlet 8, opening for feed 10 is connected with the outlet 7 of squirt pump 6, feedback outlet 8 is connected with the import of recycle pump 9, the outlet of recycle pump 9 is connected with the import of condenser 5, the outlet of condenser 5 is connected with an input terminus 4 of squirt pump 6, and two input terminuss in addition of squirt pump 6 are connected with sulfonation reaction raw material 2 and sulphonating agent 3 respectively.
Utilize above-mentioned specific equipment, the detailed step of sulphonation ring closure technology described in the utility model is as follows: sulfonation reaction raw material 2 and sulphonating agent 3 are incorporated into two input terminuss of squirt pump 6 respectively, by squirt pump 6 their direct injections are entered into reactor 1 and carry out the sulphonation ring closure reaction; Simultaneously, with recycle pump 9 the partial reaction material in the reactor 1 is sent in the condenser 5 and cools off, be controlled at-50 ℃～-15 ℃ through condenser 5 cooled material temperature, will be incorporated into another input terminus 4 of squirt pump 6 and enter into reactor 1 by squirt pump 6 injections through condenser 5 cooled materials again with sulfonation reaction raw material 2 and sulphonating agent 3; And the material after the sulphonation ring closure reaction end is drawn from the bottom discharge mouth 11 of reactor 1.
From the above mentioned as can be known, squirt pump 6 can form negative pressure when high-velocity jet, help more sucking and being ejected in the reactor 1, make them form eddy current thereby need not stir at the inwall of reactor 1 and just can carry out sufficient sulphonation ring closure and react with sulfonation reaction raw material 2, sulphonating agent 3 and through condenser 5 cooled materials; In addition, in reaction process, partial material is incorporated in the condenser 5 of reactor 1 outside and cools off, help controlling the temperature of reactant more; Therefore, use sulphonation ring closure technology described in the utility model and specific equipment thereof, just can realize serialization production, improved production efficiency greatly.
