Title
Effect of the support on a new metanethole synthesis heterogeneously catalyzed by Keggin heteropolyacids
Abstract

Keggin heteropolyacids, supported on solids of different nature and textural characteristics, were used in the reaction of anethole dimerization in order to obtain metanethole. The characterization by Fourier transform infrared spectroscopy showed that all catalysts present the Keggin structure of the heteropolyanions without degradation. Besides, all the obtained solids have strong acidity, as determined by potentiometric titration. The results of anethole conversion show that the activity of the catalysts is strongly dependent on the textural properties of the supports used to obtain the catalysts, particularly their mean pore size.
