The oxidation of hydrogen peroxide by sodium hypochlorite yields singlet oxygen. Formaldehyde is produced industrially by the catalytic oxidation of methanol. It is formed by catalytic oxidation of ammonia. Graphite oxides demonstrate considerable variations of properties depending on degree of oxidation and synthesis method. Chromium also helps resist abrasion, oxidation, and corrosion. Arene oxides are intermediates in the oxidation of arenes by cytochrome P450. It involves both oxidation and reduction of superoxide ions. Hydrogen acceptor on inosinate oxidation is NAD+. Its bleaching, cleaning, deodorizing and caustic effects are due to oxidation and hydrolysis (saponification). This proceeds via single electron oxidation and hydroxyl radicals. Jones reagent interacts with secondary alcohols resulting in oxidation to ketones. Some compounds of hafnium in lower oxidation states are known. The reaction is exothermic due to the oxidation. That leaves the question concerning what causes inhibition of glucose oxidation. One uses combustion and the other chemical oxidation.
