PROCESS FOR PREPARING DIVINYL ETHERS

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 andthe monovinyl ether is separated off from the product mixture by extractive distillation in the presence of an extractant.

Purification of alkenyl compounds

A process for purifying alkenyl compounds having a divalent or trivalent heteroatom in the à-position relative to the double bond by distillation comprises carrying out at least two distillations in which the purified alkenyl compounds are obtained from the gas phase by condensation, where the time between the first distillation after the synthesis of the alkenyl compounds and at least one further distillation is at least one day and the purified alkenyl compounds have an APHA color number of 30.
