ABSTRACT:
A method for the production of .alpha.,.beta.-unsaturated aliphatic carboxylic acids by the liquid phase oxidation of the corresponding .alpha.,.beta.-unsaturated aliphatic aldehydes, particularly acrolein and methacrolein, and the in situ decomposition of unsaturated intermediate peroxy (peroxide) compounds formed during oxidation, 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 an inorganic or organic antimony salt. The solvent employed may also be mixed with water forming a heterogeneous solvent system.
