| 摘要 |
<p>The invention relates to a process for the selective extraction of a reaction product, derived from an oxidative cleavage of an unsaturated fatty acid or of an ester derivative or of an unsaturated nitrile derivative, said reaction product being anω-functionalized acid from among C6 to C15 diacids, acid esters and acid nitriles, using as selective extraction solvent a composition comprising a mixture of water and of C1-C4 carboxylic acid. The invention also relates to the use of said process and of the extraction solvent composition for the preparation of C6 to C15 amino acid, diacid or acid ester monomers for the preparation of polycondensation polymers, in particular polyamides.</p> |
