Abstract
The utility model provides a steam distribution device for producing vitamin B1 intermediate o-chloroaniline, which comprises a reactor and a plurality of steam discharge pipes which are closely attached to the bottom of the reactor, wherein the steam discharge pipes are uniformly distributed in the reactor at intervals. In the steam distribution device for producing vitamin B1 intermediate o-chloroaniline, the inside temperature difference of the reactor is reduced, accordingly, a substrate is ensured to be stable, and the recovery rate of the substrate o-chloroaniline is improved.
Description
Technical field
The utility model relates to the Ortho-Chloro aniline production technical field, especially relates to the steam distribution device of the middle Ortho-Chloro aniline of a kind of production VITMAIN B1.
Background technology
VITMAIN B1 claims VitB1, aneurine,thiamine,vitamin B1, vitamin etc. again, is to find the earliest a kind of in the VITAMIN.
VITMAIN B1 is by a kind of vitamin B group of pyrimidine ring and thiazole ring be combined into.For the colourless crystallization body, water-soluble, very stable in acidic solution, unstable in basic solution, easily oxidized and be subjected to heat collapse.
VITMAIN B1 mainly is present in the crust and plumule of seed, and is very abundant as content in rice bran and the wheat bran, and content is also extremely abundant in yeast.Content is also abundanter in lean meat, Chinese cabbage and the celery.
At present used VITMAIN B1 is the product of chemosynthesis all.In vivo, VITMAIN B1 participates in catabolism of carbohydrate with the coenzyme form, and the effect of neuroprotective system is arranged; Can also promote enterogastric peristalsis, appetite stimulator.Thiamines is stable inadequately, and chance heat, ultraviolet ray, oxygen all chemical reaction can take place, decomposition or rotten.Thiamines can be water-soluble, is insoluble to organic solvents such as alcohol.
Be stable in 3.5 the aqueous solution at pH under the normal temperature, decompose and in neutral and basic solution, understand.Usually can be made as hydrochloride (C12H18Cl2N4OS, CAS No.67-03-8), nitrate more stable forms such as (C12H17N5O4S, CAS No.532-43-4) is used.
The method that adopts wet distillation is mostly reclaimed in the distillation of existing Ortho-Chloro aniline, its primary process comprises: vapour pipe is directly inserted contain in the middle of the mixing liquid of Ortho-Chloro aniline, show 10 to 1 ratio in the time of water vapour evaporator strip water greatly Ortho-Chloro aniline is taken out of, thereby Ortho-Chloro aniline is implemented to reclaim.
Though this method can realize Ortho-Chloro aniline is implemented to reclaim, but because water steaming process vapor temperature is higher, steam skewness often in existing steam tubular stinger and the common calandria distribution pipe, make the evaporating kettle local overheating easily, this will can damage thermo-sensitivity substrate thing, thereby have a strong impact on the rate of recovery of substrate.
The utility model content
The technical problems to be solved in the utility model is, at steam distribution inequality in the steam distribution device of Ortho-Chloro aniline in the middle of a kind of production VITMAIN B1 of prior art, defective that the substrate rate of recovery is lower, provide a kind of steam distribution evenly, the steam distribution device of Ortho-Chloro aniline in the middle of the higher a kind of production VITMAIN B1 of the substrate rate of recovery.
In order to solve the problems of the technologies described above, the utility model provides the steam distribution device of the middle Ortho-Chloro aniline of a kind of production VITMAIN B1, the a plurality of steam discharge pipes that are provided with at the bottom of comprising reactor and being close to described reactor still, described a plurality of steam discharge pipes are evenly spaced apart in reactor.
Further, in the steam distribution device of Ortho-Chloro aniline, the two ends of described a plurality of steam discharge pipes all are fixed on the circumference of described reactor in the middle of above-mentioned a kind of production VITMAIN B1.
Further, in the steam distribution device of Ortho-Chloro aniline, described a plurality of steam discharge pipes are provided with the cloth hole that is used for the water vapor evaporation in the middle of above-mentioned a kind of production VITMAIN B1.
Further, in the steam distribution device of Ortho-Chloro aniline, described cloth hole is along a plurality of steam discharge pipes uniform distribution at the bottom of the still of described reactor in the middle of above-mentioned a kind of production VITMAIN B1.
Further, in the steam distribution device of Ortho-Chloro aniline, described reactor has a baffle plate that can supply described a plurality of steam discharge pipes to wear along its fixed diameter in the middle of above-mentioned a kind of production VITMAIN B1.
Further, in the steam distribution device of Ortho-Chloro aniline, described a plurality of steam discharge pipes are that a plurality of sub-combs are formed by connecting by flange in the middle of above-mentioned a kind of production VITMAIN B1.
The steam distribution device of Ortho-Chloro aniline is by being provided with evenly a plurality of steam discharge pipes spaced apart in the middle of a kind of production VITMAIN B1 of the utility model at the bottom of the still of reactor, to be implemented in omnibearing even covering in the reactor, steam can effectively distribute when making the distillation of Ortho-Chloro aniline, reduce the temperature difference of reactor inside, thereby guaranteed the stable of substrate, improved the rate of recovery of substrate Ortho-Chloro aniline; In addition, the steam discharge pipe in the middle of a kind of production VITMAIN B1 of the utility model in the steam distribution device of Ortho-Chloro aniline is that a plurality of sub-combs are formed by connecting by flange, can change dismounting as required, has bigger handiness.
