Abstract

Process for decomposition of a cyclic alkyl ether, which in its cyclic structure comprises a 1,3-dioxa group. These cyclic diethers of acetal type are reaction products between at least one aldehyde and at least one alcohol. An aqueous solution or aqueous suspension comprising at least one cyclic diether is pH adjusted to a pH value of 1-6. The solution or the suspension is then, in the presence of at least one metallic catalyst and during inlet of hydrogen, heated to a reaction temperature of 100-200 DEG C. The cyclic alkyl ether is decomposed, whereby alcohol and aldehyde are liberated. The aldehyde reacts further through catalytic hydrogenation yielding corresponding alcohol.
