cas 1314-15-4 platinum(iv) dà-ogsaid
Àireamh CAS: 1314-15-4
Foirmle Molecular: PtO2
Cuideam moileciuil: 227.08
EINECS: 215-223-0
Susbaint Pt: Pt≥85.0% (anhydrous), Pt≥80% (hydrate), Pt≥70% (trihydrate)
Synonyms: Platinum (IV) ogsaid, platanam dà-ogsaid, platinic ocsaid
Tha catalyst Adams, ris an canar cuideachd platinum dà-ogsaid, mar as trice air a riochdachadh mar hydrate platinum(IV) oxide hydrate, PtO2•H2O.Tha e na inneal-brosnachaidh airson hydrogenation agus hydrogenolysis ann an synthesis organach.Tha am pùdar dorcha donn seo ri fhaighinn gu malairteach.Chan eil an ocsaid fhèin na inneal gnìomhach, ach bidh e gnìomhach às deidh dha a bhith fosgailte do hydrogen agus leis an sin bidh e ag atharrachadh gu dubh platanam, a tha an urra ri ath-bheachdan.
1. Catalyst hydrogenation, freagarrach airson ceangal dùbailte, ceangal trì-fhillte, hydrocarbon aromatic, carbonyl, nitrile, lughdachadh nitro.
2.Stuthan sàr-mhath airson sùghadh hydrogen.
3. Resistance le raon luach an aghaidh ìosal ann an gnìomhachas dealanach.
4. Stuthan amh airson co-phàirtean leithid potentiometer agus stuthan loidhne film tiugh airson gnìomhachas dealanach.
