| titleOfInvention | Microchannel module reaction unit is utilized to prepare the method for the bromo-6-methoxynaphthalene of 2- |
| abstract | The invention discloses a kind of method utilizing microchannel module reaction unit to prepare the bromo-6-methoxynaphthalene of 2-, by 2-methoxynaphthalene and Glacial acetic acid mixing, again bromine and said mixture are pumped in the first micro-structured reactor of microchannel module reaction unit respectively, the mol ratio of 2-methoxynaphthalene and bromine is 1:1.5-4, at 40-60 DEG C, stop 5-10min; First micro-structured reactor discharging is injected into and is filled with in the second micro-structured reactor of iron powder, at 65 ~ 95 DEG C, stop 4 ~ 8min, and the second micro-structured reactor discharging imports in frozen water, separate out a large amount of solid, suction filtration, washing, filter cake chloroform dissolves, again through 10wt%NaOH solution washing, be washed to neutrality, anhydrous sodium sulfate drying, boil off chloroform, residue dehydrated alcohol recrystallization, obtains white, needle-shaped crystals. |
