[54] PROCESS FOR SEPARATING METHACROLEIN FROM METHACRYLIC ACID IN A GAS PHASE PRODUCT FROM THE PARTIAL OXIDATION OF ISOBUTENE
[57] Abstract: A system and process for separating methacrolein (MA) from methacrylic acid (MAA) and acetic acid in the gas phase product from partial oxidation of isobutylene (IB) in two oxidation steps is disclosed. The process and system maximize recovery of all three components at minimum capital and energy cost, under conditions that minimize polymerization conditions and plugging by solids deposition in compressors, columns, etc.
