Abstract

The invention discloses a chlorination reaction kettle for ortho-position and para-position products. The reaction kettle comprises a sealing cover and a kettle body, wherein a first feeding pipe is arranged on the sealing cover; an overflow plate and a sealing plate are arranged on the two sides of the first feeding pipe respectively; overflow holes are formed in the overflow plate; a plurality of overflow pipes are arranged on the sealing plate; one end of each overflow pipe is located above the overflow plate, and the other end of each overflow pipe is located in the kettle body; a rotatingshaft is rotationally arranged in the kettle body and connected with a rotating motor; the other end of the rotating shaft is connected with a first cutting and stirring paddle and a second cutting and stirring paddle; a spraying pipe is arranged in the kettle body; the spraying pipe communicates with a second feeding pipe; spraying heads are arranged on the spraying pipe; and a discharging opening is formed in the bottom of the kettle body. Through the overflow plate and the sealing plate, the conveying of materials is more gentle, controllable and accurate; and the second feeding pipe conveys materials in a spraying mode, different materials are mixed in a collision mode firstly and then stirred and then mixed in a cutting and stirring mode, so product yield is increased.

Description

technical field [0001] The invention relates to the technical field of chlorination reaction equipment and technology, in particular to a chlorination reaction kettle for ortho-para products and a chlorination process. Background technique [0002] Reactor is a container used for physical or chemical reactions, which can realize the functions of heating, evaporation, cooling and low-speed mixing required by the process. Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicine, In the food and other industries, pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation; in the prior art, sulfur trioxide is used instead of chlorosulfonic acid for sulfonation of toluene, and then chlorine is added Sulfonic acid carries out chlorination reaction, simultaneously in chlorination process by adding ammonium sulfate as catalyzer, can effectively improve the yield of chlorination,...
