Method for producing Guerbet alcohols

摘要

The invention relates to a method for the dimerization of alcohols in the context of a Guerbet reaction, in which one or more alcohols (A) having 2 to 72 C atoms and 1 to 3 OH groups per molecule are reacted in the presence of (a) a base (B), (b) a carbonyl compound (C), and (c) a hydrogenation catalyst (H) from the group of metals ruthenium, rhodium, palladium, osmium, iridium, and platinum, said metals being in the elementary form, with the proviso that the alcohols (A) have at least one primary or secondary OH group, and that a C atom that carries at least one H atom as a substituent is directly adjacent to the C atom with said primary or secondary OH group.

主权项

1. A process for dimerizing alcohols in the manner of a Guerbet reaction, the process comprising converting one or more alcohols (A) having 2 to 72 carbon atoms and 1 to 3 OH groups per molecule in the presence of
a base (B), a carbonyl compound (C) and a hydrogenation catalyst (H) comprising a metal selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum, wherein the metal is present in elemental form,wherein the one or more alcohols (A) have at least one primary or secondary OH group and a carbon atom bearing at least one hydrogen atom as a substituent is directly adjacent to the carbon atom having this primary or secondary OH group.
