| titleOfInvention | A kind of 2-chloro-5-chloromethylthiazole synthesis reaction system |
| abstract | The invention relates to the technical field of methylthiazole synthesis, in particular to a 2-chloro-5-chloromethylthiazole synthesis reaction system. Since the chemical reaction will produce impurities, which affects the reaction time and the subsequent treatment of the reaction substrate, when the raw materials are used to enter the reactor, the 2-amino-5-methylthiazole dissolved in the organic solvent and the sodium nitrite solution are mixed in a mixing device , so that the organic matter forms oily droplets, which are easier to contact and react with hydrogen chloride gas when injected into the reactor; the dispersing device used on the top of the reactor is provided with a plurality of through holes, and the mixed liquid is sprayed from the ejector and falls directly. On the dispersing device, the mixed liquid is slowly poured into the reaction kettle through the circular hole on the dispersing device, which increases the contact time between the hydrogen chloride gas and the mixed liquid, makes the gas more soluble, and improves the production efficiency; the hydrogen chloride gas used as the chlorinating agent reacts After the filtrate is simply treated, the main component in the filtrate is hydrochloric acid, and the mixing device can apply the filtrate to save costs. |
