METHOD FOR PRODUCING METHYL METHACRYLATE Russian patent published in 2021 - IPC C12P7/62 

FIELD: biotechnology.

SUBSTANCE: present invention relates to biotechnology, in particular, to a method for producing methyl methacrylate. The method according to the invention includes the stages of: a) obtaining microorganisms in a fermentation medium in the conditions wherein said microorganisms produce a C₃-C₁₂-ester of methacrylic acid; b) producing an organic phase in contact with the fermentation medium, wherein said organic phase comprises the C₃-C₁₂-ester of methacrylic acid in a higher concentration than the concentration in the fermentation medium; c) removing the organic phase containing said C₃-C₁₂-ester of methacrylic acid from contact with the fermentation medium; and d) performing interesterification of the isolated C₃-C₁₂-ester of methacrylic acid with methanol, optionally after separation from the organic phase, resulting in production of methyl methacrylate.

EFFECT: invention provides a possibility of producing methyl methacrylate with a high degree of efficiency.
