The invention discloses a method for preparing hydrochloric acid (by-product) through hydrochloric acid tail gas absorption in chloroacetic acid production process. The method comprises the steps of absorbing hydrogenated tail gas and absorbing chlorinated tail gas, wherein absorption liquid firstly absorbs hydrogenated tail gas and then absorbs chlorinated tail gas; the absorption liquid is diluted hydrochloric acid solution after hydrogenated tail gas absorption, and the absorption liquid circulates for absorbing the chlorinated tail gas. According to the method, hydrogenated tail gas and chlorinated tail gas enter independent absorption towers respectively, the absorption liquid firstly absorbs the hydrogenated tail gas and then absorbs the chlorinated tail gas, and flows unidirectionally to gradually increase the concentration to obtain the industrial hydrochloric acid with superior quality; the small HCl absorption tower and the main HCl absorption tower adopt graphite falling film ...

The invention provides a chloroacetic acid production method and a chlorination reactor. The chloroacetic acid production method comprises the following steps: primarily mixing acetic acid, liquid chlorine and acetic anhydride according to a ratio, feeding a mixture obtained from the former step into the chlorination reactor, keeping a certain reaction temperature and a certain reaction pressure, completing chlorination reaction in a gravity field of 100-1000g, and performing separation purification on the product by using a continuous method production process after the reaction is completed, thereby obtaining a product finally. The chlorination reactor mainly comprises a reaction kettle, a cooling half-tube, a supergravity bucket, a driving motor and a mixer. By adopting the chloroacetic acid production method and the chlorination reactor provided by the invention, the macroscopic and microcosmic distribution of components in a reaction system can be improved, the side effect is reduced ...

The invention provides a production method of chloroacetic acid and a method for recovering catalysts in a production process of chloroacetic acid. The method for recovering the catalyst comprises the step that gas evaporated from chlorination reaction mother liquor in a distillation process is subjected to three stages of condensation processes, wherein a condensate generated in the first-stage condensation process flows back to the distillation process, and condensates generated in the second-stage and the third-stage condensation processes flow back to the chlorination reaction process. With the adoption of the production method and the method, actual catalysts such as acetyl chloride and chloroacetyl chloride in the production process of chloroacetic acid can be recovered almost completely, a recovery rate of HCl can be increased, and the production cost can be saved.
