- GUERBET CONDENSATION REACTION
-
The invention relates to a process for the preparation of a Guerbet alcohol, comprising the steps of: (a) providing at least one alcohol, wherein said at least one alcohol has a carbon atom bearing at least one hydrogen atom adjacent to the hydroxyl group; (b) providing a catalyst composition, wherein said catalyst composition comprises an alkaline catalyst and a copper-nickel catalyst comprised in a hydrotalcite; (c) mixing alcohol (a) with catalyst composition (b), thereby obtaining a mixture; and, (d) heating said mixture; thereby obtaining a Guerbet alcohol.

- Ni?Cu Hydrotalcite-Derived Mixed Oxides as Highly Selective and Stable Catalysts for the Synthesis of β-Branched Bioalcohols by the Guerbet Reaction
-
A series of Ni?Cu hydrotalcite-derived mixed oxides have been synthesized and evaluated as heterogeneous catalysts for the dimerization of linear aliphatic alcohols to afford β-branched Guerbet alcohols. The use of the hydrotalcite-structured catalyst precursor highly favors the catalyst stability. This Cu/Ni catalyst has an enhanced reducibility of Ni2+ species under reaction conditions, favoring the hydrogen transfer and hydrogenation capacity of the catalyst system. Catalytic results are reported for C8, mixed C8/C10, and C18 alcohol feeds, with full conversions and Guerbet product purities of 72.5–96 %.
