| abstract |
The present invention relates to new catalysts for oxidative esterification, with the aid of which, for example, (meth)acrolein can be converted to methyl (meth)acrylate. The catalysts of the invention are particularly distinguished here by their high mechanical and chemical stability, even over very long periods of time. This relates in particular to an improvement over prior art catalysts which lose activity and/or selectivity relatively rapidly in continuous operation in media with even small water contents. |
