Abstract: The present invention relates to novel catalysts for oxidative esterification, by means of which, for example, (meth)acrolein can be converted to methyl (meth)acrylate. The catalysts of the invention are especially notable for high mechanical and chemical stability even over very long periods. This especially relates to an improvement in the catalyst service life, activity and selectivity over prior art catalysts which lose activity and/or selectivity relatively quickly in continuous operation in media having even a small water content.

Abstract: A method is described for preparing a catalyst including the steps of: (i) impregnating a calcined support comprising a metal aluminate with a solution of nickel acetate at a temperature ≥40° C. and drying the impregnated support, (ii) calcining the dried impregnated support, to form nickel oxide on the surface of the support and (iii) optionally repeating steps (i) and (ii) on the nickel oxide coated support. The method provides an eggshell catalyst in which the metal oxide is concentrated in an outer layer on the support.
