三溴季铵盐性能的研究

Research of Capability of Tribromide Quaternary Ammonium Salt

首次通过自制的苄基三乙基三溴季铵盐与苯乙酮、丙酮、苯酚等的反应 ,研究了三溴季铵盐作为选择性溴化剂的相关性能。研究结果表明 ,三溴季铵盐是一种性能优良的固体溴化剂 ,操作方便 ,对人体的危害性小 ,反应速度快 ,溴化率高。最大特点是可以回收再利用 ,且回收率高 ,可以大大降低成本 ,减少污染。

The related feature of tribromide quaternary ammonium salt as selective bromide reagent was investigated by the reaction of acetophanone, propanone, phenol with self-made benzyl triethyl tribromide quaternary ammonium salt. It was found that tribromide quaternary ammonium salt was an excellent bromide reagent, which was easy to handle and had low toxicity. The reaction can process rapidly and has high bromide rate. The most remarkable property of the compound is that it can be recycled and reused in a great recycling rate. The cost can be greatly decreased and the pollution can be reduced.
