The invention discloses a device for the continuous preparation of a
Grignard reagent and a method for the continuous preparation of the
Grignard reagent through using the device. The device comprises a
solvent storage container, a
solvent-
raw material mixing container, a raw gas storage container, a preheater, a reactor, a
magnesium adding bin, a gas-liquid separator, a
Grignard reagent reception container and a
tail gas
recovery apparatus, wherein the reactor adopts a three-phase bubble
slurry column reactor. A purpose of the continuous preparation of the Grignard
reagent can be realized through using the device of the invention, and
initiation and heat
radiation problems of a
Grignard reaction can be effectively solved through adopting the three-phase bubble
slurry column reactor, so potential safety hazards of material rush-out, explosion and the like caused by the severe temperature rise of the
Grignard reaction can be effectively avoided, the obstruction of valves and pipelines by
magnesium shreds can be prevented, and the high purity Grignard
reagent can be obtained; and the
tail gas
recovery apparatus is arranged in the invention to absorb and recycle
tail gases, so the cost is saved, and the environmental
pollution is reduced, thereby cleaning and
environmental protection requirements of the preparation of the Grignard
reagent are realized.
