- PROCESS FOR PRODUCTION OF HIGH-PURITY VINYL ETHER
-
A process for producing a high-purity vinyl ether, which comprises: a step of subjecting an alcohol represented by the general formula (1) [in-line-formulae]R—O—H??(1)[/in-line-formulae] to a vinyl ether formation reaction in the presence of a catalyst to synthesize a vinyl ether represented by the general formula (2), [in-line-formulae]R—O—CH═CH2??(2)[/in-line-formulae]a step of removing the catalyst from the reaction mixture obtained in the above step to obtain a crude vinyl ether containing the vinyl ether and the unreacted raw material alcohol,a step of reacting the unreacted raw material alcohol in the crude vinyl ether, with the vinyl ether in the presence of an acid catalyst, to convert the alcohol into an acetal represented by the general formula (3), and a step of subjecting a crude vinyl ether containing the acetal (III) to distillation to obtain a high-purity vinyl ether.
