Product Name:Platinum dioxide
English Name:Platinum dioxide
CAS No.:1314-15-4
Aliases:Platinum(IV) oxide, Platinic oxide, Adam's catalyst
Molecular Formula:PtO2
Physical Properties:Brownish-black powder or black solid; melting point 450℃, relative density 10.2. Insoluble in water, concentrated acids, and aqua regia; decomposes into platinum and oxygen when heated above 500℃. Can be reduced by hydrogen or carbon monoxide; dissolves in heated sulfurous acid to form platinum(II) oxide. Exists in multiple hydrate forms: the dihydrate and trihydrate are sparingly soluble in sulfuric acid or nitric acid but readily soluble in hydrochloric acid or sodium hydroxide solution; the monohydrate is insoluble in hydrochloric acid and even aqua regia.
Uses:Widely used as a hydrogenation catalyst in organic synthesis, suitable for catalytic hydrogenation of alkenes, alkynes, nitro compounds, and other substrates. The actual catalytic species is platinum black formed by the reduction of platinum dioxide by hydrogen during the reaction.
Technical Specifications:
Formula: PtO2, molecular weight: 227.03
Appearance: brownish-black powder or black solid; melting point 450℃, relative density 10.2
Solubility: insoluble in water, concentrated acids, and aqua regia; soluble in heated sulfurous acid
Content: not less than 98%
Packaging: 1kg, 5kg
