SELECTIVE EXTRACTION OF AN OMEGA-FUNCTIONALIZED ACID AFTER OXIDATIVE CLEAVAGE OF AN UNSATURATED FATTY ACID AND DERIVATIVES
-
Paragraph 0050; 0051; 0052, (2015/11/18)
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 an ω-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.

Hydrochlorides of hydroxylamine and semicarbazide efficiently reduce peroxide products of olefin ozonolysis in a system CH2Cl2-AcOH leading to the formation of carboxylic acids and their derivatives. The application of water as the solvent component favors the increase in the fraction of nitrogen-containing organic compounds (semicarbazones, keto- and aldoximes, nitriles) and reduction in the yield of carboxylic acids.
