1. A process P¹for the manufacture of a secondary fatty alcohol, said process P¹comprising:

synthesizing an internal ketone K¹by a process P⁰comprising the decarboxylative ketonization reaction of a fatty acid, a fatty acid derivative, or a mixture thereof in a liquid phase with a decarboxylative ketonization catalyst comprising a metal compound in a reaction medium, wherein a ketone K²at liquid state, which is identical or similar to the internal ketone K¹, is introduced into the reaction medium, and

subjecting the internal ketone K¹to a hydrogenation reaction with hydrogen gas as hydrogenating agent to form the secondary fatty alcohol,

wherein the fatty acid and the fatty acid derivative independently comprise one or more compounds derived from a fatty acid cut, wherein the one or more compounds comprise a hydrocarbon chain having from 4 to 28 carbon atoms attached to a terminal carboxyl group.
