| titleOfInvention | A kind of method utilizing phosphorus tribromide to prepare acetyl bromide |
| abstract | The invention discloses a kind of method utilizing phosphorus tribromide to prepare acetyl bromide, by raw acetic acid, acetic anhydride and phosphorus tribromide are reacted at 20-40 DEG C, after having reacted, obtaining acetyl bromide product by distilling, its reaction equation is as follows: the 6 poly-Metaphosphoric acids of acetic acid+6 acetic anhydride+6 phosphorus tribromide → 18 acetyl bromide+six；The reaction raw materials of the present invention does not adopt bromine, and excessive bromination will not be caused to produce excessive bromide bromoacetyl bromide；Acid and the proportioning of anhydride, can be polymerized the water produced by effective consumption reaction intermediate product phosphorous acid；Participate in reaction raw material substantially can complete reaction, improve product conversion ratio. |
