N-甲基咪唑与氯代正丁烷亲核取代生成产物氯化1-甲基-3-丁基咪唑盐（[BMIM]Cl），其分子结构经FT-IR、13 C-NMR、UV、MS 等表征手段得以确认．用单因素分析法考察了萃取时间、萃取温度、含硫化合物种类、剂油体积比对萃取脱硫效果的影响．结果表明，在剂油比为1∶1，萃取时间为30 min，萃取温度为40℃的温和反应条件下二苯并噻吩（DBT）的单级萃取脱除率为56．2％．多级萃取和萃取-氧化耦合脱硫操作研究表明：在最优单级萃取条件下，DBT经四级连续萃取脱除率可达97．6％；萃取-氧化耦合脱硫体系对3种含硫物质均能实现85％以上的脱除．

An ionic liquid 1-methyl-3-butyl imidazolium chloride [ BMIM] Cl was synthesized through nucleophilic substitution reaction using N-methyl imidazolium and chlorobutane , and its molecular structure was confirmed by meth-ods such as FT-IR、13C-NMR、UV、MS.Effects of extraction time, temperature, sulfur compounds (T, BT or DBT) and volume ratio were presented using single factor analysis to discuss impacts on extractive desulfurization ability .In the single-stage extractive desulfurization process , removal of DBT in n-octane using [BMIM]Cl was 56.2%with vol-ume ratio of 1∶1, in 30 min at 40℃under mild reaction conditions .Also, multistage extraction and extractive-oxida-tive desulfurization process was studied:In the 4-levels consecutive extractive desulfurization , removal of DBT in n-oc-tane using [BMIM]Cl could reach 97.6% under similar reaction condition; All sulfur compounds (T, BT or DBT) could be removed more than 85%.
