Abstract
There is provided a simple and rational process for production of a vinyl ether, which comprises subjecting a 2-hydroxyalkoxy compound having, in the molecule, at least one 2-hydroxyalkoxy group and at least one functional group selected from the group consisting of a hydroxyl group and an amino group, to an intramolecular dehydration reaction in a gas phase to convert the compound into a corresponding functional group-containing vinyl ether in one step without using any subsidiary raw material or any solvent. The process is characterized by using, as a catalyst, an oxide containing an alkali metal element and/or an alkaline earth metal element and silicon.
