1-(3-Sulfopropyl)-2-mercaptobenzothiazole hydrogen sulfate containing -SO₃H and -SH, a bifunctional ionic liquid, is designed and synthesized.Its structure and thermal stability are characterized by IR, NMR and TG.When using the ionic liquid to catalyze the synthesis reaction of bisphenolfluorene, the conversion rate of 9-fluorenone reaches 100% and the selectivity of bisphenolfluorene reaches 90.1%.The acidity H₀ of the ionic liquid is used to judge the catalytic effect of the sulfonic group attached to the aromatic heterocyclic ring, and "the content of effective mercapto group" is taken to estimate the co-catalyst effect of the mercapto group attached to the aromatic heterocyclic ring.The mechanism for the synthesis of bisphenolfluorene over the bifunctional ionic liquid is elucidated.
