摘要: A process is described for preparing carboxylic acid esters via transestierification using a new heterogeneous, transition-metal transesterification catalyst of enhanced activity. The catalyst is prepared by an improved method of reacting a metal alkoxide to form an active species and absorbing the metal containing species onto a support. The method requires the controlled hydrolysis of a transition metal alkoxide to prepare an oligomer, which is then absorbed onto a hydroxylic support.
