Abstract

The invention relates to a process for preparation of at least one of methacrylic acid and a methacrylic acid ester, and a process for treatment of an aqueous phase comprising at least one organic compound comprising process steps: gas phase oxidation of at least one C4 compound to obtain a reaction phase comprising methacrylic acid; quenching of the reaction phase to obtain a crude aqueous phase; extraction of at least a part of the methacrylic acid from the crude aqueous phase to obtain a crude organic phase comprising methacrylic acid and a first aqueous phase, separation and optionally purification of at least a part of the methacrylic acid from the crude organic phase, optionally, esterification of at least a part of the methacrylic acid; extraction of at least a part of the first aqueous phase to form an extraction phase and a second aqueous phase, at least partial separation of the second aqueous phase; optionally, at least partial separation of at least one organic compound fr
