FIELD: chemistry.SUBSTANCE: invention relates to a method of producing aliphatic carboxylic acids C7 (n-CHCOOH, n-heptanoic (enanthic) acid), C9 (n-CHCOOH, n-nonanoic (pelargonic) acid) and C11 (n-CHCOOH, 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 Q{PO[W(O)(O)]}, where: Q is quaternary ammonium cation [(R)NR], where: R, Rcontain 1 to 16 carbon atoms, or of formula [CHN(n-CH)]{PO[W(O)(O)]}.EFFECT: high output and selectivity of the desired aliphatic carboxylic acid.6 cl, 12 ex, 1 tbl |
