Title
(EN) PROCESS FOR PRODUCING METAL-FREE QUERBET ALCOHOLS
(FR) PROCEDE DE FABRICATION D'ALCOOLS DE GUERBET EXEMPTS DE METAUX
Abstract
(EN) The invention relates to a method for producing metal-free and soap-free Guerbet alcohols, whereby primary and/or secondary alcohols containing 2 to 30 carbon atoms are condensed in the presence of alkaline and/or heavy metal catalysts at a high temperature, while water is removed from the reaction, and whereby the product is then directly separated from the reaction by distillation, with no additional purification process.
