Abstract:
1. A process for the synthesis of ω-functionalized acids, wherein said acids are of formula R—(CH 2 ) n —COOH, in which R represents COOH or NH 2 CH 2 and n represents an integer between 9 and 12, they are obtained from a feedstock of natural origin comprising unsaturated hydroxylated fatty acids in the acid, ester or polyol ester form comprising at least 18 carbon atoms per molecule and in that said process comprises the following stages: a) hydrogenation of the unsaturated hydroxylated fatty acids, resulting in saturated hydroxylated fatty acids, b) dehydration of the saturated hydroxylated fatty acids, resulting in monounsaturated fatty acids, c) oxidative cleavage at the double bond of the monounsaturated fatty acids, resulting in an α,ω-bifunctional compound from diacid or nitrile-acid.
