七(6-O-叔丁基二甲基甲硅烷基)-β-环糊精 (TBDMS-β-CD) 在苯-d(6) 和环己烷-d(12) 等非极性溶剂中与氯化苯有效形成包合物。通过将溶剂从苯-d(6) 改为环己烷-d(12),可以切换对 1,2- 和 1,3-二氯苯的包合选择性。此外,使用TBDMS-β-CD作为吸附剂可以完美去除绝缘油中的1,2,4-三氯苯(90 ppm)。
Heptakis(6-O-tert-butyldimethylsilyl)-beta-cyclodextrin (TBDMS-beta-CD) effectively forms inclusion complexes with chlorinated benzenes in nonpolar solvents such as benzene-d(6) and cyclohexane-d(12). The inclusion selectivity toward 1,2- and 1,3-dichlorobenzenes can be switched by changing the solvent from benzene-d(6) to cyclohexane-d(12). Moreover, 1,2,4-trichlorobenzene (90 ppm) is perfectly removed from insulating oil by using TBDMS-beta-CD as an adsorbent.
