A kind of reaction kettle for preparing trifluoromethylaniline

Abstract

The invention discloses a reaction kettle for preparing trifluoromethyl phenylamine. The reaction kettle comprises a tank body, wherein the tank body is internally provided with a stirring rod; the side wall of the tank body is provided with a plurality of reaction grooves, the heights of the reaction grooves arranged in the tank body are different, and the bottom of the tank body and the side walls of the reaction grooves are respectively provided with heaters; the bottom of the tank body is also provided with a curved surface layer, the stirring rod is provided with stirring paddles which are in one-to-one correspondence with the reaction grooves, each stirring paddles and the reaction groove which is corresponding to the stirring paddle are positioned on the same height, and the stirring paddles are internally provided with first feeding pipes are in cut through with the stirring rod; the first feeding pipes are communicated with the interior of the tank body through the stirring paddles, and the reaction grooves are internally provided with second feeding pipes. The reaction kettle provided by the invention has the advantages that the defects in the prior art can be improved, the structure is compact, the production efficiency is high, and economic benefits of the prepared trifluoromethyl phenylamine are obviously increased.

Description

technical field [0001] The invention relates to a chemical preparation device, in particular to a reaction kettle for preparing trifluoromethylaniline. Background technique [0002] Trifluoromethylaniline is an important intermediate raw material in the chemical industry, which is widely used in the preparation process of various medicines, pesticides and materials. Due to the active nature of trifluoromethylaniline and the preparation material itself, there are too many intermediate products in the preparation process, resulting in waste of materials and low purification rate. Chinese utility model patent CN201753332U discloses a synthesis device for mesitylene. Although it can reduce costs and improve purification rate to a certain extent, its structure is complex and the integration rate is low. More importantly, it reduces costs and improves purification. The effect of high efficiency is not obvious, and there is no obvious improvement in economic benefits in terms of c...
