Abstract:
1. A method for preparing a branched alcohol of formula (II) comprising subjecting at least one alcohol of formula (I) to a Guerbet reaction in the presence of an oil-soluble complex compound of a metal from the 8th, 9th or 10th group of the Periodic Table of the Elements, wherein the complex compound comprises a ligand L following said reaction, working up a mixture comprising at least one of said alcohol of formula (I) and said branched alcohol of formula (II), and said oil-soluble complex compound; and an acid of formula (III) in a form of one of its salts, wherein R wherein the working up is carried out by treating the mixture with water which can comprise an alkali metal hydroxide, and extracting the salt or salts of acid of formula (III), thereby forming a worked-up mixture, and subjecting the worked-up mixture to a further Guerbet reaction for preparing the branched alcohol of formula (II) after addition of further alcohol of formula (I), and optionally, a base.
