abstract |
The present invention relates to novel catalysts for the oxidative esterification, by means of which, for example, (meth) acrolein can be converted to methyl (meth) acrylate. The catalysts of the invention are characterized in particular by a high mechanical and chemical stability even over very long periods. This relates in particular to an improvement in the catalyst lifetime, the activity and the selectivity over prior art catalysts which relatively rapidly lose activity and / or selectivity in media with even low water content in continuous operation. |
