Abstract: A new method can be used for producing suitable improved carrier materials as a base material for catalysts for carrying out a direct oxidative esterification. In general, the catalyst is used to convert aldehydes with alcohols in the presence of oxygenic gases directly to the corresponding ester, for example, where (meth)acrolein can be converted to methyl(meth)acrylate. The catalysts used are characterized in particular by high mechanical and chemical stability as well as by good catalytic performance even over very long periods of time. This applies in particular to an improvement of catalyst service life, activity and selectivity in comparison to other catalysts.
