Abstract: Process for preparing divinyl ethers by reacting compounds having two hydroxyl groups (hereinafter referred to as diols) with acetylene, wherein the hydroxyl groups are incompletely reacted with acetylene and the resulting product mixture therefore comprises the monovinyl ether in addition to the divinyl ether and the monovinyl ether is separated off from the product mixture by extractive distillation in the presence of an extractant.

Abstract: There is described a novel woven-fabric packing 1, in which a plurality of woven-fabric layers 2 of metal or plastic filaments 3 are disposed parallel to one another. The woven-fabric layers 2 have protuberances 4, at least one protuberance 4 having an opening 5, which lies in an opening plane 6, which is oriented at an angle of 40 to 140 degrees relative to the woven-fabric layer 2. The openings 5 of woven-fabric layers 2 are all oriented in one opening direction X.
