Abstract
In the purification of the corresponding acid products obtained by oxidizing C.sub.5 to C.sub.9 organic saturated aliphatic aldehydes in the presence of a combination of manganese and copper catalysts soluble in said acids, the liquid acid reaction product is separated from the soluble catalysts by distillation in the presence of a sufficient amount of oxygen to prevent copper from plating out on the distillation equipment.
