Date Oct. 1, 1992.By reacting 1,3-propanediol with oxygen or an oxygen-containing gas in an aqueous alkaline solution in the presence of a palladium containing catalyst substrate, alkaline salts of 3-hydroxypropionic acid are produced in good yield when the catalyst is used in an amount that corresponds to 0.1 to 3.0% by weight of palladium, based on the 1,3-propanediol.
