Abstract (en)

[origin: WO2014072641A1] The invention concerns a method for the selective extraction of a reaction product, originating from an oxidative cleavage of an unsaturated fatty acid or of an ester derivative or of an unsaturated nitrile derivative, said reaction product being a co-functionalised acid chosen from the C6 to C15 diacids, ester-acids and nitrile-acids, using, as the selective extraction solvent, a composition comprising a mixture of water and C1-C4 carboxylic acid. The invention also concerns the use of said method and the extraction solvent composition for the preparation of C6 to C15 amino acid, diacid or ester-acid monomers for the production of polycondensation polymers, in particular polyamides.
