Abstract
A process for producing catalysts by acid activation of phyllosilicates and coating with catalytically active metal ions wherein the acid activation is carried out in the presence of catalytically active metal ions. The solution which forms during acid activation together with the remaining solution which contains the excess, catalytically active cations are separated. The catalysts can be used for proton-catalyzed and Lewis acid-catalyzed reactions, especially for conversion of higher olefins with aromatic hydroxy compounds and amines, for esterification and dehydration reactions and for purification of aromatics.
