RHODIUM-CATALYZED OXIDATION PROCESS FOR PRODUCING CARBOXYLIC ACIDS

摘要

ABSTRACT OF THE DISCLOSUREA one-step process for forming a carboxylicacid and its anhydride directly from the correspondingolefin which comprises reacting the olefin with carbonmonoxide, hydrogen and oxygen in the presence of arhodium complex catalyst stabilized by a pentavalentGroup V ligand, such as a phosphine oxide. Alterna-tively a carboxylic acid can be produced by oxidationof an aldehyde in the presence of a rhodium complexcatalyst stabilized by said pentavalent Group V ligand.
