摘　　要：一步法合成一种离子液体(Ionic Liquid,IL)1-十四烷基-3-甲基咪唑溴化盐[C_(14)MIm]Br,作为萃取剂替代有机溶剂用于油基钻屑的萃取处理。考察IL种类、加量、萃取时间及pH值等对萃取效果的影响,实验结果表明,油基钻屑与萃取液质量比为1∶1、pH值大于7时,萃取在20min时可以达到平衡,油基钻屑中油去除率大于88%,IL吸附损失率小于0.9%,分离后的IL可直接重复利用7次。1-myristyl-3-methyl imidazole bromide salt ionic liquid abbreviated as[C_(14)MIm]Br was synthesized by one-step.It is used as an extraction agent instead of organic solvent in oil-based drilling cuttings treatment.By investigating the ionic liquid type,amount,extraction time and pH value on the effects of the extraction,it was found that the best extraction effect was received when the oil-base drilling cuttings and extracted liquid mass ratio was 1:1,pH higher than 7and 20min's extraction.Under the optimal condition,oil removal rate was more than 88%,and the adsorption loss rate of ionic liquid was less than 1%.The separated ionic liquid could be directly reused for six times.
