Abstract:
The present invention relates to a process for producing methyl methacrylate, comprising the following steps: A) producing methacrolein and B) reacting the methacrolein obtained in step A) in an oxidative esterification reaction to give methyl methacrylate, characterized in that the two steps A) and B) take place in a liquid phase at a pressure of from 2 to 100 bar, and step B) is carried out in the presence of a heterogeneous noble-metal-containing catalyst comprising metals and/or comprising metal oxides.

Claim (Index 1):
A process for producing methyl methacrylate, the process comprising:\n A) producing methacrolein from propanal and formaldehyde and B) reacting the methacrolein in an oxidative esterification reaction to obtain methyl methacrylate, wherein the producing A) and the reacting B) take place in a liquid phase at a pressure of from 2 to 100 bar, and the reacting B) is carried out in the presence of a heterogeneous noble-metal-comprising catalyst comprising at least one selected from the group consisting of gold and nickel.
