Abstract
The utility model discloses an acesulfame condensation device, which comprises a reactor body and a cooling clamp sleeve outside the reactor body. The inner wall of the reactor body is provided with two drip tubes, the bottoms of the two drip tubes extend to the bottom in the reactor body, and the lower parts of the two drip tubes are respectively provided with a group of distribution drip holes. The acesulfame condensation device has a simple structure and is convenient to operate. With diversion fins, the contact area of reaction materials can be enlarged. Since the materials are fed after being dispersed by the drip tubes with the distribution drip holes, the reaction materials can be mixed fully, the condensation time can be reduced, and the production efficiency can be increased.
Description
Technical field
The utility model relates to the synthetic field of acesulfame potassium, specifically is a kind of acesulfame potassium condensation reaction device.
Background technology
Acesulfame potassium, chemical name acesulfame potassium are commonly called as AK sugar, be artificial synthetic the 4th generation sweetener, sugariness is 200 times of sucrose.Be desirable safe, heat-resisting, mouthfeel well in vivo not metabolism do not put aside the sweetener that physicochemical property is stable.Be widely used in food, beverage, medicine, cosmetics, commodity.
The synthetic method of acesulfame potassium is more, use at present both at home and abroad be more advanced, raw material is easy to get, nontoxic, synthetic route that step is short.At first do catalyst and ketene dimer condensation reaction at triethylamine and produce acetyl, acetamide sulfonic, use the sulfur trioxide dehydration condensation, make acesulfame potassium with the potassium hydroxide neutralization again with sulfamic acid, through concentrated, decolouring, crystallization, dry finished product packing.
The synthetic chemistry reaction equation of acesulfame potassium is:
Condensation:

Cyclization:
Neutralization:
Condensation reaction operation during acesulfame potassium is produced drops into sulfamic acid earlier in reactor, make solvent with carrene, adds triethylamine, glacial acetic acid, ketene dimer more successively and reacts.Because sulfamic acid and the carrene that drops into do not dissolve each other in advance, though mix but two-phase is disperseed still uneven, the solid sulfamic acid easily sinks to the bottom, and methylene chloride is than great, the material that adds from top is difficult for contacting with the sulfamic acid of bottom, react bad control, it is low to react insufficient yield, and the time is tediously long wants 30 hours.
The utility model content
The technical problems to be solved in the utility model provides a kind of acesulfame potassium condensation reaction device, and it is tediously long and react inadequate problem to solve the acesulfame potassium condensation reaction elementary reaction time.
The technical solution of the utility model is:
Acesulfame potassium condensation reaction device comprises the cooling jacket that kettle and kettle are outer, and described inner wall of kettle is provided with two dropping pipes, and two bottoms that drip pipes all extend into the interior bottom of kettle, and two bottoms that drip pipe all have component cloth dropping hole.
Described inner wall of kettle is provided with two deflectors, is provided with one group of level distributing fin obliquely on the deflector.
Described two deflectors are with respect to the symmetrical installation of kettle axial line.
All stretch out outside the kettle on described two tops that drip pipe, and two drip pipe is to intersect installation with respect to the symmetrical installation of kettle axial line and with two deflectors, and described distribution drips the hole opening towards inner wall of kettle.
The bottom of described cooling jacket is provided with cooling liquid inlet, and its top is provided with cooling liquid outlet.
Described dropping pipe is used to drip triethylamine, glacial acetic acid and ketene dimer.
The utility model is by increasing fin flow guiding, strengthen the mixing severe degree of material, the bottom material can not deposited, and reaction mass disperses to add in the kettle from the bottom by having the dropping pipe that drips the hole that distributes, and mixes rapidly fully, and helping reaction heat is removed by chuck, the good control of reaction, yield improves, and owing to reaction contact area increases, reduce whole condensation reaction time, and then improved the production efficiency of whole production line.
The utility model is simple in structure, and is easy to operate, by the contact area of distributing fin augmenting response material, and disperse to add material by having the dropping pipe that drips the hole that distributes, it is more even that reaction mass is mixed, thereby shorten the time of condensation reaction, improved production efficiency.
