- Method of producing vinyl ether
-
PROBLEM TO BE SOLVED: To provide a method for producing vinylether which gives high conversion rate of ether exchange reaction, excels in recyclability of raw material components and enables mass production at low cost industrially. SOLUTION: This method comprises: performing an ether exchange reaction between vinylethers and alcohols in the presence of a transition metal catalyst; and during the reaction or after completion of the reaction, while bubbling oxygen in the reaction mixture, distilling low boiling point components out to concentrate the reaction mixture. The low boiling point components may be distilled at around 50-100°C. In this reaction, the vinylethers may be used at a rate of excess molar equivalent to the alcohols. The oxygen may be bubbled at a rate of 5-100 L/min to 1 mole of the transition metal catalyst. The transition metal catalyst may be a paradium complex and/or cobalt complex.
