Reactor capable of simultaneously producing trichloroethylene and tetrachloroethylene

Abstract

The invention discloses a reactor capable of simultaneously producing trichloroethylene and tetrachloroethylene. The reactor comprises a reaction container; an auxiliary device convenient for removinghigh-boiling residues and recycling a catalyst is arranged in the reaction container; the reactor capable of simultaneously producing the trichloroethylene and the tetrachloroethylene is provided with the auxiliary device, settlement blocks generated in chlorination reaction in the production process of the trichloroethylene and the tetrachloroethylene are treated by the auxiliary device, the high-boiling residues on the settlement blocks are removed, the remaining ferric chloride catalyst is fed into the reaction container, so that the settlement blocks are prevented from hindering heat dissipation, the ferric chloride catalyst can be recycled, and the failure of the reaction mother liquor is avoided.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a reactor capable of simultaneously producing trichlorethylene and tetrachlorethylene. Background technique [0002] Trichlorethylene is an organochlorine solvent with excellent performance and wide application, and it is the strongest solvent among C2 organochlorine solvents. Its main purpose is: excellent metal degreasing lotion, mainly used as cleaning agent for metal parts and electronic components in color TV, refrigerator, automobile, air conditioner, precision machinery, microelectronics and other industries. Ethylene is mainly used for organic synthesis of chemical raw materials and intermediates - refrigerant F-125 (replacing CFC-12), etc., as well as solvents, dry cleaning agents, metal degreasing solvents, and can also be used as an anthelmintic and fat extractant Wait.

AI Technical Summary

Problems solved by technology

[0003] When preparing trichlorethylene and tetrachlorethylene by chlorination, the chlorination of acetylene is completed in the mother liquor (tetrachloroethane liquid phase), wherein suspended powdery FeCl3 is used as a catalyst, and the FeCl3 used is block, The FeCl added after crushing before each use; easily settles and mixes unevenly with the mother liquor, and the mother liquor of the chlorination tower will fail after being used for a period of time. On the one hand, the FeCl in the chlorination tower settles and is unevenly distributed; Since the chlorination reaction of acetylene will produce high boilers such as pentachloroethane and hexachloroethane, the produced high boilers will form lumps with the settled FeCls, which will affect the heat dissipation of the reaction and seriously affect the progress of the reaction.
