Branched alcohol are prepared in the Guerbet condensation reaction by reacting C1-C20 primary alcohols in the presence of a catalyst system comprising platinum supported by high surface area activated carbon and potassium or sodium hydroxide. Very small amounts of catalyst have been found effective at 175°C to 210°C in providing high conversions to the condensed alcohol product of about 85% in a 1-5 hour reaction time.
