Description
Technical field
The present invention relates to technology and this kind technology specialized apparatus of hydrolysis 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.Involved in the present invention to the synthetic method of acesulfame potassium to be based on the patent No. be US4; 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 is that material dropping that sulphonation ring closure has been reacted is in reactor usually, 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, in reaction, also must in the chuck of reactor, feed refrigerated brine, sulphur trioxide and water react rapid liberated heat, control reaction temperature 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 reactive mode can not realize serialization production, and can only be discontinuity production, and efficient is lower.
Summary of the invention
Technical problem to be solved by this invention is: hydrolysis process and this kind technology specialized apparatus in a kind of synthesis of acetyl sulfanilic acid potassium process of can serialization production and not needing to stir are provided.
For solving the problems of the technologies described above, main technical principle of the present invention is: the material that sulphonation ring closure has been reacted with squirt pump continuous high speed ground sprays in the hydrolytic reaction pot, and in reactor, form eddy current with the thorough mixing reactant, pump is played circulation again, reaction mass and water are cooled off, discharging continuously again after reaction is finished by condenser.Do not need whipping appts, solved and leaked and interruption production problem.
The concrete technical scheme that the present invention adopts is: the hydrolysis process in a kind of synthesis of acetyl sulfanilic acid potassium process, be characterized in: the material that sulphonation ring closure has been reacted is incorporated into an input terminus of squirt pump, by squirt pump the material direct injection is entered into the hydrolytic reaction pot reaction that is hydrolyzed; Simultaneously, with recycle pump the partial reaction material in the hydrolytic reaction pot is sent in the condenser with water and cools off, to be incorporated into another input terminus of squirt pump through the cooled material of condenser again, and enter into hydrolytic reaction pot by the squirt pump injection with the material that sulphonation ring closure has reacted; And the material after the hydrolysis reaction end is drawn from the bottom of hydrolytic reaction pot.
Above-mentionedly can preferably be controlled at-10 ℃～15 ℃ through the cooled material temperature of condenser.
In addition, a kind of specific equipment of hydrolysis process recited above, 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.
Advantage of the present invention is: use hydrolysis process of the present invention and specific equipment thereof in synthesis of acetyl sulfanilic acid potassium process, not only technology and equipment are simple, need not whipping appts, and can realize serialization production, have improved production efficiency greatly.
Description of drawings
Fig. 1 is the structure principle chart of the specific equipment of hydrolysis process of the present invention.
Embodiment
The invention 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 above-mentioned specific equipment, the detailed step of hydrolysis process of the present invention is 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, make them form eddy current thereby just need not stir and to carry out sufficient hydrolysis reaction at the inwall of hydrolytic reaction pot 10 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 of the present invention and specific equipment thereof, just can realize serialization production, improved production efficiency greatly.
