Document Type and Number:
Japanese Patent JP6884140
Kind Code:
B2
Abstract:
In particular the present invention relates to an optimized workup of the reactor effluent from the oxidative esterification of methacrolein by means of which process waste streams can be minimized and process water can be recycled in optimal fashion. The methacrylic acid generated in the process is also optimally recovered and isolated or converted into the commodity alkyl methacrylate. This process moreover has the advantage that fewer demands than described in the prior art are placed on plant apparatus configuration.
