摘要： The present invention relates to a process for the preparation of diols of the general formulae I
and/or its monoesters of the general formulae II
and/or the general formulae III
wherein R₁ and R₂ are the same or different and each denotes a lower alkyl having 1 to 4 carbon atoms, preferably a methyl, whereby aldehydes containing a hydrogen atom in alfa position are condensed in a multi phase reaction environment and having the general formulae IV where in R₁ and R₂ have the meanings given above, in the presence of a catalytic system consisting of a phase transfer catalyst and an alkaline substance.
