Zusammenfassung:	A method for the production of a 1,3-dioxolane represented by the general formula III: wherein R is hydrogen atom or an alkyl group of 1 to 5 carbon atoms and R is hydrogen atom or an alkyl group of 1 to 2 carbon atoms or a phenyl group, which method comprises reacting an aldehyde represented by the general formula I wherein R has the same meaning as defined above, with an alkylene oxide represented by the general formula II: wherein R has the same meaning as defined above, in an alkylene glycol solvent corresponding to said alkylene oxide in the presence of at least one catalyst selected from the group consisting of bromides of alkali metals, iodides of alkali metals, bromides of alkaline earth metals, and iodides of alkaline earth metals.
