Mapana Journal of Sciences, vol. 11(2), pp 1-160975-3303http://journals.christuniversity.in/index.php/mapana/article/view/259http://hdl.handle.net/10204/6703Copyright: 2012 Mapana Journal of Sciences, vol. 11(2), pp 1-16The present study has undertaken the Friedel-Crafts benzylation of aromatics over the V2O5/ZrO2 catalysts systems. Catalysts with different V2O5 content (0-15wt %) was prepared by wet impregnation method and characterized by XRD, BET surface area, FTIR and 5’V NMR techniques. The surface acidic properties were determined by temperature programmed desorption of NH3, cumene cracking and perylene adsorption. Under the optimized reaction conditions, these catalysts are found to be very effective and considerably more selective than the conventional homogeneous Lewis acid catalysts. The investigation of vanadia systems-catalyzed benzylation of o-xylene with benzyl chloride revealed that the catalytic activity and product selectivity are sensitive to the precise reaction parameters and can be related to the Lewis acidity of the systems. The reaction is found to be very clean and produces the desired monoalkylated product with high yield.enV2O5/ZrO2 catalystsFriedel-Crafts alkylationLewis acidityArticleKesavan Pillai, S., Gheevarghese, O., & Tleane, I.
