Procedure

A mixture of 520 g (5 moles) of 2,2-dimethyl-1,3-propanediol, 479 g (5.5 moles) of 85% strength methoxy-acetaldehyde and 250 ml of cyclohexane was heated with 5 g of the ion exchanger Lewasorb AC 10 under a water separator until water no longer separated off. The ion exchanger was filtered off, the solvent was stripped off under reduced pressure and the residue was subjected to fractional distillation under reduced pressure. 632 g (79% yield) of 2-methoxymethyl-5,5-dimethyl-1,3-dioxane of boiling point 96° C./60 mbar were obtained.
