A catalyst for oxidn. of CH2:CH2 to MeCHO contained an acid soln. of Pd(II) salt with an oxidizer additive. For increasing the activity and stability and for decreasing the corrosion capacity of the catalyst, instead of an acid soln. of Pd(II) compd., a Pd salt soln. with noncomplexing or weakly complexing anion, e.g., sulfate perchlorate, phosphate, acetate, was used, in aq. or H2O-alc. soln. of strong mineral acids, the ions of which do not complex or weakly complex with Pd, e.g., sulfuric, perchloric, phosphoric acids. Quinones with redox potential ≤-0.4 V were used as oxidizers.
