| titleOfInvention | A kind of HBCD preparation method |
| abstract | Separate, dry three steps the invention discloses a kind of HBCD preparation method, including bromination, washing.Bromination is that raw material cyclodoecatriene and bromine are added dropwise in the mixed solvent of isobutanol and dichloroethanes respectively, and the mol ratio of bromine and cyclodoecatriene is 3.05~3.08:1.Three sections of dropwise addition process point is warming up to 50 DEG C ± 2 DEG C, and total reaction time is 3~4 hours；Washing is separated, the mixed solvent that solid phase adds dichloroethanes to be prepared with isobutanol that bromination reaction is completed to be isolated in liquid, isolates solid phase after being uniformly mixed again, is subsequently adding ethanol and is washed 2 times, obtains filtering solid phase.It is that will wash isolated solid phase in 80 DEG C of ± 2 DEG C of drying to dry separation, obtains white solid powder product.Product clip band can be influenceed the complete impurity of the non-bromination of fusing point to remove by the HBCD preparation method that the present invention is provided, the method washed using solvent, improve product purity, raise product fusing point. |
