Zusammenfassung:	PURPOSE:To obtain the titled high-purity compound useful for applications, e.g. urethane resin, silver salt photographic films, etc., by bringing ethyl acetate containing a very small amount of diethyl acetal into contact with a specific strong acidic cation ion exchange resin in the presence of a given amount of water and distilling the resultant product. CONSTITUTION:Ethyl acetate containing a very small amount of diethyl acetal (ethyl acetate of >=99.0 purity produced for industrial use is used. When the amount of the diethyl acetal contained as an impurity is >=500ppm, the ethyl acetate is distilled to reduce the amount to
