Abstract

The invention relates to a washing kettle, in particular to an improved washing kettle for producing p-chloropropiophenone. The technical scheme adopted by the invention is that the improved washing kettle for producing the p-chloropropiophenone comprises a kettle body, wherein a stirring device is arranged in the kettle body and comprises a stirring shaft; the stirring shaft is provided with an upper stirrer and a lower stirrer; a paddle axis of the upper stirrer is perpendicular to that of the lower stirrer; stirring blades of each of the upper stirrer and the lower stirrer separately comprise one group of left paddle and right paddle which are fixedly arranged on two sides of a driving shaft; an upper cover is provided with a feeding pipe; the feeding pipe extends to the lower part of the lower stirrer inside a kettle body; a discharging channel is arranged at the bottom of the kettle body; the improved washing kettle further comprises a circulating tank; the top of the circulatingtank is communicated with the lower part of the kettle body through a pipeline; the bottom of the circulating tank is communicated with the discharging pipeline through a pipeline. The improved washing kettle disclosed by the invention has the advantages of reasonable structure, good use effect, facilitation for improvement on washing effect and suitability for popularization and use.

Description

technical field [0001] The invention relates to a washing kettle, in particular to an improved washing kettle used for producing p-chloropropiophenone. Background technique [0002] p-Chloropropiophenone is an aromatic asymmetric ketone compound, a white crystalline solid. With a melting point of 34-37°C, p-chloropropiophenone is an important intermediate with a structural role. It is mainly used as a pharmaceutical intermediate, and can also be used as a fine chemical raw material for the synthesis of fine chemical products containing a p-chlorobenzene ring structure in the molecule. At the same time, it can also be used as intermediates of other medicines and pesticides. During the production of p-chloropropiophenone, it is necessary to use a water washing kettle to fully stir, crush and wash the materials, and separate the impurities contained in the raw materials to improve the quality of the product. The existing water washing kettle has a simple structure, which res...
