  • Patent number: 11702386
    Abstract: Process P1 for the manufacture of a secondary fatty alcohol, said process P1 comprising synthesizing an internal ketone K1 by a process P0 comprising the decarboxylative ketonization reaction of a fatty acid or the like in a liquid phase with a metal compound as catalyst in a reaction medium, wherein a ketone K2 at liquid state, which is identical or similar to the internal ketone K1, is introduced into the reaction medium, and subjecting the internal ketone K1 to a hydrogenation reaction with hydrogen gas as hydrogenating agent to form the secondary fatty alcohol. Use of the secondary fatty alcohol manufactured by the process P1 for the manufacture of an internal olefin or of an internal olefin sulfonate.

  • Patent number: 11267781
    Abstract: Method (M) for the preparation of an end compound from an internal ketone, said method comprising: —synthesizing the internal ketone by a process (P) for the decarboxylative ketonization of a fatty acid, a fatty acid derivative or a mixture thereof in a liquid phase with a metal compound as catalyst in the substantial absence of added solvent, wherein the fatty acid, fatty acid derivative or mixture thereof is added in sequential steps, the first step taking place at a temperature sequentially at a temperature from 100° C. to 270° C., —causing the internal ketone to react in accordance with a single or multiple chemical reaction scheme involving at least one reagent other than the internal ketone, wherein at least one product of the chemical reaction scheme is the end compound that is not further caused to be chemically converted into another compound.
