Abstract: The invention relates to a process for the production of diols with a special structure which are characterized by formula (I). These diols are substances which, besides two OH groups, contain a C?C double bond so that they are suitable as monomers for the production of polymers. The process comprises hydrolyzing a corresponding cyclic precursor in aqueous medium in the presence of an acid dissolved in that medium, the hydrolysis being accompanied by the elimination of a carbonyl compound, and subsequently neutralizing the acid present in the reaction mixture with a base, the base having a pKb value above 0.18 and preferably above 3.0 and being present in heterogeneous form.
