Chemistry & industry
Uses & manufacturing
Uses
Used as a hydrogenation catalyst; [Merck Index] Platinum(IV) oxide hydrate (PtO2.H2O) is a hydrogenation catalyst. Other platinum oxides have little commercial use: Platinum(II) oxide (PtO) and platinum(II) oxide hydrate (PtO.H2O). [Ullmann]
General Manufacturing InformationPlatinum oxide (PtO2): ACTIVE
Applications
UsesHydrogenation: Reduction of alkynes to alkenes, Catalyst/ In the presence of H2，PtO2 can be reduced to Pt black which is the active form;Hydrogenation of nitro compounds to amines;Hydrogenation of ketones;The removal of phenyl groups attached to a heteroatom;Reduction of aromatic ring;Dehydrogenation: Dehydrogenation of 1,4-diketone to pyridazine;Oxidation: Oxidation of alcohols to carbonyl compounds;Others: Resistance, Low resistance range;Hydrogen absorbing material: Excellent hydrogen absorbing capacity;Thick film circuit and electronic component: Insoluble in aqueous solutions (water) and extremely stable;Solid oxide fuel cells and oxygen generation systems: Cathode/certain perovskite structured oxides are electronically conductive.
UsesPlatinum(IV) oxide is used as catalyst for hydrogenation reactions. It is applied in the hydrogenation of alkenes to alkanes, nitro compounds to amines and ketones to alcohols. It is also involved in the hydrogenolysis of cyclopropyl group in to an isopropyl group and in selective oxidation of primary alcohols.
UsesAs catalyst in hydrogenations. The actual catalyst is platinum black which is formed in situ by reduction of the PtO2 by the hydrogen used for the hydrogenation. Especially useful for reduction at room tempereture and hydrogen pressures up to 4 atmospheres. Suitable for the reduction of double and triple bonds, aromatic nuclei, carbonyl groups, nitro groups, and nitriles.
General DescriptionPlatinum(IV) oxide has been used for the reduction of citernyl bromide to form (S)-3,7-dimethyloctylbromide. Prepared by Adams′ nitrate fusion method.
