METHOD OF PRODUCING ALIPHATIC CARBOXYLIC ACIDS Russian patent published in 2015 - IPC C07C51/285 C07C53/126 B01J31/34

Abstract RU 2554000 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing aliphatic carboxylic acids C7 (n-C₆H₁₃COOH, n-heptanoic (enanthic) acid), C9 (n-C₈H₁₇COOH, n-nonanoic (pelargonic) acid) and C11 (n-C₁₀H₂₁COOH, n-undecanoic (undecylic) acid) via catalytic oxidation of corresponding alpha-alkenes. The method of producing aliphatic carboxylic acids is carried out by oxidising the corresponding alkenes with hydrogen peroxide solution in a two-phase system in the presence of a catalyst. The process is carried out in the presence of a metal complex catalyst of general formula Q₃{PO₄[W(O)(O₂)₂]₄}, where: Q is quaternary ammonium cation [(R₁)₃NR₂]⁺, where: R₁, R₂ contain 1 to 16 carbon atoms, or of formula [C₅H₅N(n-C₁₆H₃₃)]₃{PO₄[W(O)(O₂)₂]₄}.

EFFECT: high output and selectivity of the desired aliphatic carboxylic acid.
