Process for the production of methyl methacrylate

Abstract: In the esterification of methacrylic acid by reaction with methanol in aqueous solution with sulfuric acid catalyst, the product stream from the esterification reactor is first separated into two immiscible liquid phases, an organic phase containing methyl methacrylate product and an aqueous phase containing the sulfuric acid. The aqueous phase from the first separation is mixed with an aqueous feed stream containing the reactant methacrylic acid. The sulfuric acid causes separation of two immiscible liquid phases consisting of an organic-rich phase containing methacrylic acid which is suitable for feed directly to the esterification reactor and a water-rich phase which contains the sulfuric acid. The water-rich phase is stripped of organics which are recycled and the sulfuric acid residue is concentrated by removing water and recycled to the reactor.
