Abstract

There is provided a process for producing Guerbet alcohols not containing any heavy metals or soaps, wherein primary and/or secondary alcohols having 2 to 30 carbon atoms are condensed at elevated temperature in the presence of alkaline catalysts and/or heavy metal catalysts while eliminating the reaction water, and the reaction product is immediately separated by distillation without any additional purification.
