  • Patent number: 10179755
    Abstract: A method for preparing a branched alcohol by dimerizing an aliphatic monoalcohol having three or more carbon atoms in the presence of a base and a catalyst. The dimerization reaction is performed under atmospheric pressure while injecting a hydrogen gas. With this method, it is possible to obtain a dimerized alcohol with excellent yield even when using a branched aliphatic monoalcohol as the starting material.
