摘　　要：制备了溴代丁基吡啶四氯化钛([Bpy]B r-TiC l4)离子液体,并将其用作溶剂和Lew is酸催化剂催化辛基酚己二酸酯的Fries重排反应,合成出了辛基酚己二双酮。实验结果表明,使用离子液体操作简单,产物易分离提纯。在反应温度为60℃、反应时间为6 h的条件下,重排反应产物的选择性高达100%,收率提高到65%以上。The ionic liquid of 1-butylpyridium bromide/TiCl4 was prepared and used as solvent as well as a Lewis acid catalyst in Fries rearrangement of adipic acid bis （4-octylphenol） ester. The rearrangement product of bis （2-hydroxy-5-octylphenyl） hexane-1,6-dione was easily obtained and purified. The operation conditions were simplified ,the selectivity was up to 100% and the yields could be over 65% under the conditions of reaction temperature of 60℃ and reaction time of 6 hours.
