To provide a method for producing a Guerbet alcohol without necessity of the use of a solvent, capable of enhancing the conversion and the yield. A method for producing a Guerbet alcohol, including the following steps 1 to 3 in this order: step 1: preparing a liquid composition containing an aliphatic alcohol and a base; step 2: holding the liquid composition at 100 C. or more and 180 C. or less to thereby adjust a water amount in the liquid composition to less than 0.28% by mass; and step 3: setting the liquid composition to be more than 180 C.

A method and catalyst for forming higher alcohols from lower alcohol feedstocks. In one application a highly selective and stable copper pseudo-single-atom supported on MgOAl.sub.2O.sub.3 catalyst is provided which provides ethanol condensation to higher alcohols at 50% yields and 85% selectivity is demonstrated with stable catalyst lifetime over 500 hours in a continuous flow system. In some applications a Guerbet condensation process is further utilized to yield a higher alcohol at a selectivity of near 90%.

##STR00002##

wherein R.sup.2 represents a linear C.sub.7-C.sub.13 alkyl group; and relates to a base oil composition comprising the base oil.

An improved isobutanol synthesis process is provided which proceeds through the formation of mixed alcohols from syngas. The two-step process avoids the slowest -carbon addition reaction in the conventional one-step, direct isobutanol synthesis process. Once ethanol and propanol are produced in the first reaction zone, they can react with methanol and/or syngas in a second reaction zone to produce isobutanol through the fast -carbon addition reaction in the presence of catalysts, resulting on significantly improved isobutanol productivity.
