Abstract:
The present invention relates to a process for preparing alkyl methacrylates, especially MMA, and methacrylic acid, based on methacrolein, which has been oxidatively esterified in a second process stage. Methacrolein is obtainable in principle from C 2  and C 4  units. The present process has the advantage that the alkyl methacrylate and methacrylic acid can be obtained in a simple manner, in high yields and high purities, either as a mixture or as isolated product streams. In particular, the process of the invention has the great advantage that especially the ratio of the desired methacrylic acid and alkyl methacrylate, especially MMA, products can be adjusted freely within a wide range and varied by chemical engineering measures and operating parameters.

Claim (Index 7):
The process according to  claim 2 ,\n wherein the alkyl methacrylate-containing composition from c) is passed into the extraction I for performance of d), and the organic phase from d) is then guided into the separation stage M for performance of g), in which case a substream of an alkyl methacrylate phase from the separation stage M is then fed to the reactor III for performance of e).
