ABSTRACT:
3-hydroxy propionic acid is obtained in high yield through the catalytic oxidation of 3-hydroxy propionaldehyde with O.sub.2 or an O.sub.2 -containing gas in the aqueous phase in the presence of a platinum-group catalyst, in particular a Pd or Pt supported catalyst. The catalyst is used in a quantity corresponding to at least 10 percent by weight of the platinum-group metal relative to 3-hydroxy propionaldehyde.
