    摘要: 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 C
    6 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.

    摘要: A method for producing a salt of an amine with a cyanoalkenylcyclopropanecarboxylic acid, the method comprising a first step of mixing a carboxylic acid compound represented by formula (2C) and at least one amine selected from the group consisting of primary amines and secondary amines in an organic solvent; a second step of depositing a salt of the amine with a cyanoalkenylcyclopropanecarboxylic acid represented by formula (2) from the mixture obtained in the first step; and a third step of recovering the salt deposited in the second step;

    wherein, R represents an alkyl group optionally having a substituent or a halogen atom.
