A kind of method that 2,6 difluoro toluene continuous oxidation prepares 2,6 difluorobenzaldehydes

The method that 2,6 difluoro toluene continuous oxidations of one kind of the invention prepare 2,6 difluorobenzaldehydes, belongs to organic synthesis technology field.The method is that, with 2,6 difluoro toluene compounds are raw material, and one or more metal ion complexs of cobalt, molybdenum, bromine are catalyst, hydrogen peroxide is oxidant, and acetic acid is solvent, continuous by 2 in tubular reactor, the oxidation of 6 difluoro toluenes prepares the technology of 2,6 difluorobenzaldehydes.This method mild condition, the reaction time is short, and raw material availability is high, is capable of achieving the effective control in course of reaction, and safety and stability, continuous operation, production efficiency is high.
