Abstract: A method of extracting (meth)acrylic acid from an aqueous reaction medium into an organic phase in contact therewith is described. The aqueous reaction medium is formed from at least one base catalyst and at least one dicarboxylic acid selected from maleic, fumaric, malic, itaconic, citraconic, mesaconic, and citramalic acid or mixtures thereof in aqueous solution and contains the base catalysed decarboxylation products of the base catalysed reaction. The method includes either the addition of at least one of the said dicarboxylic acids and/or a pre-cursor thereof to the aqueous reaction medium to enhance the solvent extraction of the (meth)acrylic acid into the organic solvent or maintaining the level of base catalyst to dicarboxylic acid and/or pre-cursor at a sub-stoichiometric level during the extraction process. The method extends to a process of producing (meth)acrylic acid, its esters and polymers and copolymers thereof.

Abstract: The present invention relates to a process for the production of methyl methacrylate. The process of the present invention comprises the steps of: a) providing a microorganism in a fermentation medium, under conditions which said microorganism will produce a C3-C12 methacrylate ester; b) providing an organic phase in contact with the fermentation medium, said organic phase including C3-C12 methacrylate ester in a higher concentration than that in the fermentation medium; c) removing organic phase containing the said C3-C12 methacrylate ester from contact with the fermentation medium; and d) transesterifying the removed C3-C12 methacrylate ester with methanol, optionally after separation from the organic phase, to produce methyl methacrylate.
