Molecular Formula: PtO2
Kulemera kwa Maselo: 227.08
EINECS: 215-223-0
Pt zokhutira: Pt≥85.0% (anhydrous), Pt≥80% (hydrate), Pt≥70% (trihydrate)
Mawu ofanana: Platinamu(IV) okusayidi, platinamu dioxide, platic okusayidi
Chothandizira cha Adams, chomwe chimadziwikanso kuti platinamu dioxide, nthawi zambiri amaimiridwa ngati platinamu(IV) oxide hydrate, PtO2•H2O.Ndiwothandizira hydrogenation ndi hydrogenolysis mu organic synthesis.Ufa wakuda wakudawu ndiwopezeka pamalonda.Oxidi yokhayo sichiri chothandizira, koma imakhala yogwira ntchito pambuyo pokumana ndi haidrojeni pomwe imasandulika kukhala platinamu yakuda, yomwe imayambitsa machitidwe.
1. Chothandizira cha hydrogenation, choyenera kugwirizanitsa pawiri, chomangira chapatatu, chonunkhira cha hydrocarbon, carbonyl, nitrile, kuchepetsa nitro.
2.Zida zabwino kwambiri za hydrogen mayamwidwe.
3. Kukaniza ndi mtengo wotsika wotsutsa mumakampani amagetsi.
4. Zida zopangira zinthu monga potentiometer ndi zida zamtundu wafilimu zamagetsi zamagetsi.
