| description | The invention discloses a 2-chloro-5-trichloromethyl pyridine rectification purification method and device. Rectification purification of 2-chloro-5-trichloromethyl pyridine is implemented by using adevice for rectification purification of 2-chloro-5-trichloromethyl pyridine. By adopting the device for rectification purification of the 2-chloro-5-trichloromethyl pyridine, purification of a crudeproduct of 2-chloro-5-trichloromethyl pyridine can be efficiently implemented, the device is simple in structure and low in cost, and together with a purification method for the crude product of the 2-chloro-5-trichloromethyl pyridine, the purification rate of the crude product of the 2-chloro-5-trichloromethyl pyridine can be greatly increased.
