摘要:
The invention relates to a method for producing methylmethacrylate, comprising the steps: A) producing methacrolein and B) conversion of the methacrolein obtained in step A) into methylmethacrylate in an oxidative esterification reaction, characterized in that the two steps A) and B) are carried out in liquid phase at a pressure of 2 to 100 bar and step B) is carried out in the presence of a heterogeneous, noble metal-contaiing catalyst comprising metals and/or metal oxides.
