Abstract
An improved process for obtaining acrylic acid and methacrylic acid by oxidation of acrolein and methacrolein respectively, with molecular oxygen in the vapor phase, at a reaction temperature of about 200ºC to about 500º c, in the presence of a catalyst and, optionally, in presence of water vapor, wherein the improvement comprises using as catalyst the one described by the formula *** (see formula) in which x is an element of the rare earths or a mixture thereof.
