Description

Reactor equipment for preparing trichloropropane

Technical Field

The utility model belongs to the technical field of preparation, and particularly relates to reactor equipment for preparing trichloropropane.

Background

At present, trichloropropane is a chemical reagent commonly used in industry, and is a colorless flammable liquid. Slightly soluble in water, soluble in oils, fats, waxes, chlorinated rubbers and most resins; the method is mainly used for producing 2, 3-dichloropropene, is also a better solvent, can be used as a raw material of chlormequat chloride or avenanthine No. 1 pesticide, and can also be used as a novel material intermediate; as chlorine gas is required to be introduced in the manufacturing process and is toxic gas, once the gas leaks, the consequences are unreasonable, a large amount of heat is released in the reaction process, and potential safety hazards can be caused if the gas is not cooled.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) toxic gas is easy to leak;

(2) the heat released by the reaction is easy to cause potential safety hazard;

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides a reactor device for preparing trichloropropane.

The present invention is thus achieved, a reactor apparatus for producing trichloropropane, comprising a housing; the inside retort that is equipped with of shell, retort are equipped with upper seal cover and lower closing cap respectively from top to bottom.

Furthermore, an upper sealing ring is arranged at the joint of the upper sealing cover and the reaction tank.

Further, a lower sealing ring is arranged at the joint of the lower sealing cover and the reaction tank.

Furthermore, the upper sealing cover is provided with an air inlet, a lamp hole, a sight glass hole, a thermometer sleeve opening, a manhole, a chlorine gas discharge hole, a condensate water inlet and other spare holes.

Furthermore, a feed hole, a chlorine feed hole, a condensed water outlet and other spare holes are arranged on the lower sealing cover.

Furthermore, a steam outlet, a nameplate and other standby holes are formed in the reaction tank body.

Further, a thermometer is arranged at the lower part of the opening of the thermometer sleeve.

By combining all the technical schemes, the utility model has the advantages and positive effects that:

the utility model relates to a reactor device for preparing trichloropropane, which is characterized in that chlorine and propylene react, heating is needed in the reaction process, free radical type reaction is carried out to generate trichloropropene, and then the trichloropropene reacts with the chlorine to obtain trichloropropane; the upper sealing ring and the lower sealing ring can ensure the tightness of equipment when chlorine is introduced, and prevent gas leakage; this equipment can also external condensate cooling system, prevents the potential safety hazard that the jar body high temperature caused.

The utility model solves the problems of certain risk, non-continuity and low reaction conversion rate due to intermittent reaction, and the continuous process can achieve the conversion of more than 99 percent and the intermittent reaction is about 90 percent, thereby greatly reducing the production cost.

The utility model reduces the side reaction, has little residual chlorine which is not reacted in the intermittent reaction, and has the hidden trouble problem of safety risk.
