摘要:
The invention relates to new catalysts for oxidative esterification that allows (meth)acrolein, for example, to be converted to methyl(meth)acrylate. The catalysts of the invention are characterized in particular by great mechanical and chemical stability even over very long periods of time. There is an improvement especially over prior art catalysts that lose activity and/or selectivity relatively quickly during continuous operation in media having even a low water content.
