TL;DR: Wax coating compositions of improved water resistance are prepared by subjecting a molten blend of petroleum wax and an ethylene-vinyl acetate copolymer to controlled oxidation, either in the absence of any oxidation inhibitor, or in the presence of only limited amounts thereof as mentioned in this paper.
Abstract: Wax coating compositions of improved water resistance are prepared by subjecting a molten blend of petroleum wax and an ethylene-vinyl acetate copolymer to controlled oxidation, either in the absence of any oxidation inhibitor, or in the presence of only limited amounts thereof, so as to effect a partial oxidation of the copolymer without significant oxidation of the wax component. Following the oxidation, inhibitor is added to provide commercially effective concentrations thereof.

TL;DR: A catalyst useful for the oxidation of organic compounds, particularly the partial oxidation of benzene with molecular oxygen to produce maleic anhydride, comprises the oxides of molybdenum and vanadium and a minor amount of boron as mentioned in this paper.
Abstract: A catalyst useful for the oxidation of organic compounds, particularly the partial oxidation of benzene with molecular oxygen to produce maleic anhydride, comprises the oxides of molybdenum and vanadium and a minor amount of boron. A preferred form of the catalyst further includes phosphorus and at least one member of the group consisting of cobalt, nickel and iron, and sodium.

TL;DR: In this paper, a study of partial oxidation of toluene to benzaldehyde was performed using Mo03-P200 catalysts with different P/Mo ratios, where Xm0n was metal oxide.
Abstract: Vapor-phase oxidation of toluene to benzaldehyde was investigated using Mo03-P200 catalysts with different P/Mo ratios and Mo03-P205-Xm On, (1: 0.2: 0.1) catalysts, where Xm0n was metal oxide. Addition of P205 in a proper amount to MoO3 improved the activity, the stability, and the selectivity to benzaldehyde. Addition of Bi203 to the Mo0, -P205 system increased the activity, but when the Bi203 content was such that Bi/Mo 0.2, oxidation reactions of produced benzaldehyde to CO and CO2 were accelerated. All the metal oxide additives, except for Sb203, increased the activity. The efficiency was in the order Sn02 Cr203 TzTi02 V205 A1203 Bi203 NiO Co203 Fe203. In addition, Sn02, Cr203, and TiO2 were remarkably efficient for the activity stabilization. However, the additives which have a high efficiency for the activity increase showed a tendency to accelerate the consecutive oxidation of produced benzaldehyde to benzoic acid.
