A kind of preparation method of the bromo- 4- bromo nitrobenzene phenol of 3- |
| abstract |
The invention discloses a kind of industrialized process for preparing of the bromo- 4- bromo nitrobenzene phenol of 3-.The industrialized process for preparing of the bromo- 4- bromo nitrobenzene phenol of the 3- synthesizes the bromo- 4- bromo nitrobenzene phenol of 3- through nitro in upper bromine, diazotising and hydrolysis three-step reaction using para-fluoroaniline as initial feed.The bromo- 4- bromo nitrobenzene phenol of the 3- that this process obtains is yellow solid, and purity 97.5%, every step feed stock conversion respectively reaches 100%, and the total recovery of whole process reaches 25.8%. |
