Chivakwa chemuviri

Phe makemikari formula yesirivheri oxide is ag2o, nehuremu hwemanyorerwe 231.74. Brown kana grey black solid, nejira re7.143g / cm, nekukurumidza inogadzirisa kuumba sirivheri uye okisijeni kuma 300 ℃. Zvishoma zvishoma mumvura, zvinyoro-nyoro mu nitric acid, ammonia, sodium huku, uye potassium cyanide mhinduro. Kana iyo mhinduro yeAmoni yashandiswa kumusoro, inofanira kubatwa nenzira yakakodzera. Kufumurwa kwenguva refu kunogona kugadzirira zvakanyanya kuputika nhema makristasi - sirivheri kana sirivheri sulfa. Inoshandiswa se oxidant uye girazi colant. Yakagadzirirwa nekuita sirivheri nitrate mhinduro ine sodium hydroxide solution.

Brown cubic crystalline kana brown dema poda. Bond Urefu (AG O) 205pm. Kuora pamadhigirii 250, kusunungura okisijeni. Density 7.220g / cm3 (25 degrees). Chiedza zvishoma nezvishoma. Ita ne sulfutic acid kuti iburitse sirivha sulfate. Zvishoma zvishoma mumvura. Shuwa muAmmoni mvura, Sodium Hydroxide Solution, Dilute nitric acid, uye sodium thosoufate mhinduro. Kusaziva mu ethanol. Yakagadzirirwa nekuita sirivheri nitrate mhinduro ine sodium hydroxide solution. Wet AG2O inoshandiswa seyakaona kana ichitsiva maHalogens neHydroxyl mapoka mu organic synthesis. Zvakare inoshandiswa seicho chengetedzo uye yemagetsi mudziyo zvinyorwa.

 

Chemical chivakwa

Wedzera mhinduro ye caustic kune sirivha nitrate mhinduro yekuiwana. Chekutanga, mhinduro yesirivheri hydroxide uye nitrate inowanikwa, uye sirivheri hydroxide inodaira kuita sirivheri uye mvura pamhepo tembiricha. Sirivan oxide inotanga kuora kana ichipiswa kusvika 250 ℃, kusunungura oksijeni, uye nekukurumidza inogadzirisa pamusoro 300 ℃. Zvishoma nezvishoma manyorerwo mumvura, asi zvinyoro-nyoro pamhinduro dzakadai se nitric acid, Amonia, potassium cyanide, uye sodium thisosulfate. Mushure mekuratidzwa kwenguva refu kumhinduro yaro yeAmoni, yakasimba inoputika makristasi matema anogona dzimwe nguva sirivha - pamwe sirivheri kana sirivheri. Mune organic Synthesis, mapoka ehydroxyl anowanzoshandiswa kutsiva halgens kana se oxidants. Inogona zvakare kushandiswa seyakahwanda muindasitiri yegirazi.

 

Nzira yekugadzirira

Sirivha oxide inogona kuwanikwa nekuita alkali simbi hydroxide ine sirivheri nitrate. Mhinduro yekutanga yekutanga inogadzira yakasarudzika sirivha hydroxide, iyo inobva yangoita kuti uwane mvura nesirivheri. Mushure mekugeza like, inofanira kuoma pane isingasviki 85 ° C, asi zvakaoma kwazvo kubvisa mvura sirivheri kubva kumucheto sirivheri pakupedzisira, iyo sirivha yetsvina ichaora. 2 AG + 2 OH- → 2 AGOH → AG2O + H2O.

 

Kushandiswa kwekutanga

Inonyanya kushandiswa sechairisa yemakemikari synthesis. Iyo inoshandiswawo seinochengetedza, zvemagetsi mudziyo zvinyorwa, girazi colant, uye kugeda mumiririri. Inoshandiswa kune zvinangwa zvekurapa uye segirazi rinotora mumiririri, colant, uye mvura inonatsa; Inoshandiswa seyekupukuta uye kurongedza mumiririri wegirazi.

 

Application chiyero

Sirivheri nzombe ndiyo yeakasvika electrode yezvinyorwa zvesirivheri yerudzi. Iyo zvakare isina kusimba oxidant uye isina kusimba base mune organic synthesis, iyo inogona kuita ne 1,3-disubstituted imidazole munyu uye benzimidazole munyu wekuburitsa amaseni. Inogona kutsiva ligands isina kugadzikana senge cyclooctadiene kana acetonitrile se carbene kuendesa reagents kuti synthestize transition yesimbi carbene carbene carbene carbene. Mukuwedzera, sirivheri nzombe dzinogona kushandura maronda organic uye chlorides mune alcelohols pane yakadzika tembiricha uye pamberi pemaputi emvura. Izvo zvinoshandiswa pamwe chete neIodomethane zvakare reghylation reagent yekuongorora svutugadzike uye Hoffman elimination maitiro, pamwe nexidation yeAldehydes kune carboxylic acids.
