ABSTRACT:
A process for the liquid phase oxidation of .alpha.,.beta.-unsaturated aldehydes, and the in situ decomposition of unsaturated intermediate peroxy (peroxide) compounds formed during oxidation, to the corresponding unsaturated aliphatic acid which comprises passing oxygen or an oxygen-containing gas through an inert solvent solution of the aldehyde at a suitable temperature and pressure in the presence of a catalytic amount of a thallium salt. The solvents employed may be mixed with water forming a heterogeneous solvent system.
