Reaktionsschritte

A mixture of 590 g (5 moles) of 2-ethyl-2-methyl1,3-propanediol, 479 g (5.5 moles) of 85% strength methoxyacetaldehyde and 500 ml of chloroform was heated with 10 g of pyridinium p-toluenesulfonate under a water separator until water no longer separated off. The remaining solution was deionized using a mixed-bed ion exchanger, the solvent was removed under reduced pressure and the residue was distilled. 774 g (89% yield) of 2-methoxymethyl-5-ethyl-5-methyl-1,3-dioxane of boiling point 58° C./1 mbar were obtained.
