cas 1314-15-4 platinum(iv) dioxide
Helu CAS: 1314-15-4
Formula Molekala: PtO2
Kaumaha Molekala: 227.08
EINECS: 215-223-0
ʻO ka nui o ka Pt: Pt≥85.0% (anhydrous), Pt≥80% (hydrate), Pt≥70% (trihydrate)
Nā huaʻōlelo like: Platinum(IV) oxide, platinum dioxide, platinic oxide
ʻO ka mea hoʻouluulu a Adams, i ʻike ʻia hoʻi ʻo platinum dioxide, ua hōʻike pinepine ʻia ʻo ia he platinum(IV) oxide hydrate, PtO2•H2O. He mea hoʻouluulu ia no ka hydrogenation a me ka hydrogenolysis i ka synthesis organik. Loaʻa kēia pauka ʻeleʻele ʻeleʻele i ke kālepa. ʻAʻole he mea hoʻouluulu ikaika ka oxide ponoʻī, akā lilo ia i mea hana ma hope o ka hōʻike ʻana i ka hydrogen ma laila e hoʻololi ai i ka platinum ʻeleʻele, nona ke kuleana no nā hopena.
1. Mea hoʻonui hydrogenation, kūpono no ka pilina pālua, pilina ʻekolu, hydrocarbon ʻala, carbonyl, nitrile, hōʻemi nitro.
2.Nā mea hoʻopili hydrogen maikaʻi loa.
3. Ke kū'ē me ka pae waiwai kū'ē haʻahaʻa ma ka ʻoihana uila.
4. Nā mea maka no nā ʻāpana e like me ka potentiometer a me nā mea laina kiʻiʻoniʻoni mānoanoa no ka ʻoihana uila.
