Abstract

This invention relates to gas-to-liquid and allowed reactors; - to improve the reliability and efficiency of the reactor. The reactor consists of a cylindrical body with a regime-exchangeable jacket, gas distributors, a settling tank and a diaphragm. The gas enters through the gas distributors, the reaction takes place in the reactor, the reaction products are collected in the settling chamber. 1 il. with SP about O)

Description

The invention relates to chemical engineering and is intended to implement the chlorination process of the hydrochloride (U-picoline, which proceeds to form the target hexa- and hept of chloropicolins, insoluble in the initial reaction mass, and can also be used in chemical industry to conduct barbotage gas-liquid processes.

The purpose of the invention is to increase the reliability and efficiency of the reactor by eliminating the formation of gas plugs and water hammer.

General view.

The reactor consists of a cylindrical body 1 with a jacket 2, a crushing unit 3, a bottom 4, lower gas distributors 5, a settling chamber 6 located under the gas distributors 5, a diaphragm 7 installed at the junction of the settling chamber 6 with the housing 1,

nozzles 8-11, siphon 12, ducks

13 to maintain the liquid level in the reactor and the valve 14.

The chlorinating reactor operates in continuous countercurrent mode as follows.

The initial o-picoline hydrochloride is metered into the reactor, which is filled with chlorine-picolin mixture, through pipe 8 through siphon 12. Chlorine enters from below through gas distributors 5, splashes through the liquid layer, mixes the reaction mass and chlorinates it. Exhaust gases leave the reactor through pipe 9 and are fed for sanitization. The presence of jacket 2 allows the desired temperature to be maintained in the reaction zone.

Chlorination of d-picoline hydrochloride with d-picoline produces target hexa- and gy chloropicolines, which are not mixed.

however, they are distributed throughout the entire volume of the reaction zone in the form of an emulsion due to gas mixing.

The mixture of chloropicolines flows from the reaction zone to the settling chamber 6, due to the presence of the diaphragm 7 and the selection of the appropriate geometrical dimensions of the settling chamber .6, the mixing of the liquid is prevented and the separation of the resulting fraction and the lighter reaction mass occurs. The gas entering the settling chamber 6 is separated and returned to the reaction zone. As a result, the heavy fraction, which does not contain gas and non-chlorinated chloropicolines, is uniformly discharged through pipe 11 and duck 13

from the reactor. Valve 14 serves to empty the reactor during repair work. When conducting gas-liquid reactions with homogeneous liquids, the presence of a settling chamber 6 also 25 increases the reliability of the reactor, since it prevents the formation of gas jams and water hammer in the discharge line 1 and ensures a uniform flow of fluid in it.

Shape, la out of shadow

The chlorinating reactor, which encloses the cylindrical body with a heat-exchange jacket, pinch and bottom, gas distributors and process nozzles, characterized in that it is equipped with a gas tank and a hydraulic hammer that is connected to with it through the diaphragm settling chamber, the inner diameter of which is less than the diameter of the reactor vessel, while the gas distributors are installed above the diaphragm.
