Title: Catalysis By Some Pillared Montmorillonites
Author: Rahna, K Shamsudeen; Dr. Sugunan, S
Abstract: In the present study, we have prepared and evaluated the physical and chemical properties and catalytic activities of various single, mixed and modified pillared montmorillonites. The single oxide pillared clays include AI-, Fe- and Cr-pillared montmorillonites. The mixed oxide pillared montmorillonites such as Fe-AI and Cr-AI pillared systems with various Fe(Cr)/Al ratios are also prepared. Modification of iron-pillared system is done by vanadia impregnation. Characterisation using various physico-chemical techniques and a detailed study of acidic properties are also carried out. Major part of our work is oriented to evaluate the catalytic activity of the pillared systems towards certain important catalytic reactions. Our samples are found to be excellent catalysts for the reactions namely Friedel-Crafts benzylation and benzoylation, methylation of aniline and catalytic wet peroxide oxidation of phenol.
