method for the production of methyl methacrylate |
| abstract |
patent summary: "method for the production of methyl methacrylate". The present invention relates to a method for the production of methyl methacrylate comprising the following steps: a) methacrolein production and b) reaction of the methacrolein obtained in step a) in an oxidative esterification reaction to provide methyl methacrylate characterized in because both steps a) and b) occur in a liquid phase at a pressure of from 200 to 10,000 kpa (2 to 100 bar), and step b) is performed in the presence of a heterogeneous noble metal-containing catalyst comprising metals and / or comprising metal oxides. |
