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.

Peroxide products of oleic acid ozonolysis treated with semicarbazide and hydroxylamine hydrochlorides in methanol are predominantly converted into methyl nonanoate and dimethyl nonanedioate, in 2-propanol, into isopropyl nonanoate and monoisopropyl ester of nonanedioic acid, and also into nonanenitrile, in tetrahydrofuran and in a mixture of acetic acid with dichloromethane, into nonanoic and nonanedioc acids, and also in nonanal oxime and 9-(hydroxyimino)nonanoic acid.

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.
Process for Producing Nitrile-Fatty Acid Compounds
-
, (2014/02/15)
The invention relates to a process for synthesizing a nitrile-fatty acid (heminitrile) from unsaturated fatty acids, in the form of an acid or a simple ester or a “complex” ester of triglyceride type, which is first of all converted into an unsaturated fatty nitrile which is subjected to oxidative cleavage using H2O2 as oxidizing agent. This process can be used for preparing polyamide monomers, such as ω-amino acids or diamines or diacids equivalent to said heminitrile and for obtaining polyamides from raw materials which are of natural origin and from a renewable source.
