文摘

Heptakis(6-O-tert-butyldimethylsilyl)-β-cyclodextrin (TBDMS-β-CD) effectively forms inclusion complexes with chlorinated benzenes in nonpolar solvents such as benzene-d₆ and cyclohexane-d₁₂. The inclusion selectivity toward 1,2- and 1,3-dichlorobenzenes can be switched by changing the solvent from benzene-d₆ to cyclohexane-d₁₂. Moreover, 1,2,4-trichlorobenzene (90 ppm) is perfectly removed from insulating oil by using TBDMS-β-CD as an adsorbent.
