Method for producing alkenyl ethers
Alkenyl ethers are prepared by reacting the corresponding alcohols or phenols with acetylenes in the liquid phase in the presence of basic alkali metal compounds and a cocatalyst comprising compounds of the formula (Ia) and/or (Ib) R 1 O-(CH 2 CH 2 CH 2 CH 2 O) n- H (Ia) R 1 O-(CH 2 CH 2 CH 2 CH 2...
