| Abstract: | Titania sulphated titania and transition metal loaded (9%) sulphated titania have been prepared by sol gel method and characterized by XRD, FTIR, BET surface area, EDX and UV-vis DRS. Surface acidity of these catalysts is determined by temperature programmed desorption of ammonia. Alkylation of phenol with ten-butanol in the vapour phase over the prepared systems has been studied at 1 atm and 160-220oC. The reaction provides high selectivity of alkylation at the para position . The product selectivity has been correlated with the surface acidity of the systems. |
