Abstract

The invention relates to a process for the production of Guerbet alcohols by condensation of aliphatic alcohols in the presence of alkali metal or alkaline earth metal hydroxides as catalyst using the Guerbet reaction, in which the initial pressure in the reactor corresponds to the vapor pressure of the alcohol components used and, during the reaction, the pressure is continually reduced to the vapor pressure of the reaction mixture at the particular temperature.
