| 摘 要： | 利用氟硼酸甲基丁基咪唑离子液体 ([BMIM] [BF4 ] )作为反应介质 ,过渡金属三苯基膦配合物作为催化剂 ,在90～ 15 0℃、1.0～ 1 5MPa下研究了双环戊二烯加氢制备桥式四氢双环戊二烯 (endo -TCD)的反应 ,获得了高转化率和选择性 ,所得产物与离子液体催化体系不溶而分层。在有机助溶剂和氢气 (4 0MPa)存在下 ,endo -TCD在氯化甲基丁基咪唑 -氯化铝 (AlCl3摩尔分数为 67% )离子液体中可高效地异构为金刚烷。同时考察了离子液体催化体系及不同反应条件对反应的影响

| Abstract: | At the temperature range of 90 to 150 ℃ and pressure range of 1 0 to 1 5 MPa , Rh(PPh 3) 3Cl catalyzed hydrogenation of dicyclopentadiene has been demonstrated to proceed readily in 1-n-butyl-3-methylimidazolium tetrafluoroborate (BF 4) with easy catalyst/solvent recycling ,and the inconvenient separation of the products could be avoided When hydrogen pressure was 4 0 MPa, the hydrogenated product tetrahydrodicyclopentadiene successfully isomerized to adamantane in 1-n-butyl-3-methylimidazolium heptachlorodialuminate (Ⅲ) ionic liquid, small amount of organic solvent was the effective promoter for the isomerization . |
