text: For example, using a palladium catalyst such as Pd black or Pd/C, preferably at a catalyst loading of between about 0.1 and about 5 mole % based on g-atoms phosphorus charged and a temperature of between about 40° C. and about 150° C., preferably between about 55° C. and about 95° C., hypophosphorous acid is essentially quantitatively hydrolyzed to phosphorous acid without significant formation of phosphoric acid.
