Numera CAS: 1314-15-4
Fuafua mole: PtO2
Malosi mole: 227.08
EINECS: 215-223-0
Pt mea i totonu: Pt≥85.0% (anhydrous), Pt≥80% (susu), Pt≥70% (trihydrate)
Synonyms: Platinum(IV) oxide, platinum dioxide, platinic oxide
Adams' catalyst, e ta'ua foi o le platinum dioxide, e masani ona fa'atusaina o le platinum(IV) oxide hydrate, PtO2•H2O.Ose fa'atosina mo le hydrogenation ma le hydrogenolysis i le fa'aogaina o meaola.O lenei pauta enaena uliuli o lo'o maua fa'apisinisi.O le oxide lava ia e le o se faʻamalosi malosi, ae e faʻamalosi pe a uma ona faʻaalia i le hydrogen lea e liua i le platinum black, lea e nafa ma tali.
1. Hydrogenation catalyst, talafeagai mo sootaga lua, fusi tolu, hydrocarbon aromatic, carbonyl, nitrile, nitro faaitiitia.
2.Mea e sili ona lelei e fa'aoga ai le hydrogen.
3. Tete'e fa'atasi ma le maualalo o fa'atauga fa'atauva'a i totonu o pisinisi fa'aeletoroni.
4. Mea mata mo vaega e pei o potentiometer ma mea mafiafia laina ata tifaga mo alamanuia faaeletonika.
