      Choline chloride and 1,4-butane sultone were combined to obtain a sulphonic acid-functionalized ionic liquid. The structural properties of the ionic liquid were evaluated with AT-IR, NMR, mass and elemental analysis. The Bronsted acidity of the ionic liquid was confirmed from the AT-IR analysis of pyridine-adsorbedsamples. The catalytic activity of the ionic liquid was studied for the preparation of phenol from cumene hydroperoxide by Hock process. Various reaction parameters were optimized and kinetics of the reaction was evaluated. This Bronsted acidic choline chloride-butane sultone-based ionic liquid was highly selective towards the conversion of cumene hydroperoxide to phenol. Ease of use and recovery, low environmental impact, and effective reduction of activation energy make it a potential candidate for industrial production of phenol
