Qaanuunka molecular: PtO2
Miisaanka Molecular: 227.08
EINECS: 215-223-0
Waxyaabaha ku jira Pt: Pt≥85.0% (anhydrous), Pt≥80% (hydrate), Pt≥70% (trihydrate)
La mid ah: Platinum(IV) oxide, platinum dioxide, platinic oxide
Adams 'catalyst, oo sidoo kale loo yaqaan platinum dioxide, ayaa badanaa u taagan sida platinum(IV) oxide hydrate, PtO2•H2O. Waa kicinta hydrogenation iyo hydrogenolysis ee isku-dhafka organic. Budada madow ee madow waa ganacsi ahaan. Oksaydhku laftiisu maaha kicin firfircoon, laakiin waxa uu noqdaa mid firfircoon ka dib marka la soo bandhigo hydrogen halkaas oo ay u beddesho platinum madow, kaas oo ka masuul ah falcelinta.
1. Biyo-qaade biyo-diid, ku habboon dammaanad laba-jibbaaran, dammaanad saddexley ah, hydrocarbon caraf udgoon, karbonyl, nitrile, dhimis nitro.
2.Alaabada nuugista hydrogen ee heer sare ah.
3. Iska caabinta qiimaha iska caabbinta hooseeya ee warshadaha elektiroonigga ah.
4. Alaabta ceeriin ee qaybaha sida potentiometer-ka iyo alaabta xadhkaha filimka dhumuc weyn leh ee warshadaha elektiroonigga ah.
