| titleOfInvention | Industrial production method for continuously preparing 2-chloro-5-methylpyridine |
| abstract | An industrial production method for continuously preparing 2-chloro-5-methylpyridine relates to the technical field of production of pesticide intermediates, and adopts a multi-kettle series connection mode, takes benzylamine as a main starting material, takes solid phosgene or phosgene as a chlorinating agent, and continuously prepares the 2-chloro-5-methylpyridine in the presence of a catalyst. The invention overcomes the defects of small capacity, unstable quality control, long preparation time and the like of batch reaction equipment, and has the characteristics of high reaction yield and good product quality, wherein the total preparation yield is more than or equal to 87.0 percent, and the content of 2-chloro-5-methylpyridine is more than or equal to 99.5 percent. |
