Diethylene glycol divinyl ether was obtained by base-catalyzed reaction of diethylene glycol with ethyne and distilled. The diethylene glycol divinyl ether obtained was stabilized with 100 ppm by weight of potassium hydroxide and had an APHA color number of 45. After storage for 5 days at 25° C., the diethylene glycol divinyl ether was redistilled from the still pot of the same apparatus as in Example 2 at about 0.5 kPa abs. The purified diethylene glycol divinyl ether obtained via the top had an APHA color number of only 3.
