ABSTRACT:
Process for the preparation of olefinically unsaturated ethers by reacting a conjugated diene and a lower alkanol with the aid of an acidic catalyst in the presence of a non-basic aprotic polar solvent. The olefinically unsaturated ethers are of interest as solvents and gasoline additives and can also be used as starting materials for e.g. the synthesis of ketones.
