Dukiyar jiki

Tsarin sinadaran Phe na oxide na azurfa shine Ag2O, tare da nauyin kwayoyin 231.74. Brown ko launin toka baƙar fata, tare da yawa na 7.143g/cm, da sauri bazuwa ya zama azurfa da oxygen a 300 ℃. Dan mai narkewa cikin ruwa, mai narkewa sosai a cikin nitric acid, ammonia, sodium thiosulfate, da potassium cyanide mafita. Lokacin da aka yi amfani da maganin ammonia, ya kamata a bi da shi a cikin lokaci. Tsawon bayyanarwa na iya haifar da lu'ulu'u masu fashewa sosai - nitride na azurfa ko sulfite na azurfa. An yi amfani da shi azaman oxidant da launin gilashi. An shirya ta hanyar amsa maganin nitrate na azurfa tare da maganin sodium hydroxide.

Brown cubic crystalline ko launin ruwan kasa foda. Tsawon Bond (Ag O) 205pm. Rushewa a digiri 250, yana sakin oxygen. Yawaita 7.220g/cm3 (digiri 25). Hasken a hankali yana rubewa. Yi amsa tare da sulfuric acid don samar da sulfate na azurfa. Dan mai narkewa cikin ruwa. Mai narkewa a cikin ruwan ammonia, maganin sodium hydroxide, dilute nitric acid, da maganin sodium thiosulfate. Insoluble a cikin ethanol. An shirya ta hanyar amsa maganin nitrate na azurfa tare da maganin sodium hydroxide. Ana amfani da Wet Ag2O azaman mai haɓakawa lokacin maye gurbin halogens tare da ƙungiyoyin hydroxyl a cikin haɗin kwayoyin halitta. Hakanan ana amfani dashi azaman kayan adanawa da kayan lantarki.

 

Chemical dukiya

Ƙara maganin caustic zuwa maganin nitrate na azurfa don samun shi. Da fari dai, ana samun maganin hydroxide na azurfa da nitrate, kuma hydroxide na azurfa yana bazuwa zuwa oxide na azurfa da ruwa a cikin zafin jiki. Azurfa oxide yana fara rubewa lokacin da aka yi zafi zuwa 250 ℃, yana sakin iskar oxygen, kuma yana saurin rubewa sama da 300 ℃. Dan mai narkewa a cikin ruwa, amma mai narkewa sosai a cikin mafita kamar nitric acid, ammonia, potassium cyanide, da sodium thiosulfate. Bayan tsawaita bayyanar da maganin ammoniya, lu'ulu'u masu fashewa masu ƙarfi na iya yin hazo a wasu lokuta - yuwuwar nitride na azurfa ko azurfa iminide. A cikin ƙwayoyin halitta, ana amfani da ƙungiyoyin hydroxyl sau da yawa don maye gurbin halogens ko azaman oxidants. Hakanan za'a iya amfani dashi azaman mai launi a cikin masana'antar gilashi.

 

Hanyar shiri

Azurfa oxide za a iya samu ta hanyar amsa alkali karfe hydroxide tare da azurfa nitrate. [1] Halin da ya fara haifar da hydroxide na azurfa mara kyau, wanda nan da nan ya rushe don samun ruwa da azurfa oxide. Bayan wanke ruwan sama, dole ne a bushe shi a ƙasa da 85 ° C, amma yana da matukar wahala a cire ɗan ƙaramin ruwa daga oxide na azurfa a ƙarshe saboda yayin da zafin jiki ya karu, oxide na azurfa zai rube. 2 Ag+ + 2 OH- → 2 AgOH → Ag2O + H2O.

 

Amfani na asali

Anfi amfani dashi azaman mai kara kuzari don haɗa sinadarai. Hakanan ana amfani da ita azaman abin adanawa, kayan na'urar lantarki, kalar gilashi, da wakili mai niƙa. Ana amfani da shi don dalilai na likita kuma azaman wakili mai goge gilashi, mai launi, da mai tsarkake ruwa; An yi amfani da shi azaman polishing da mai canza launi don gilashi.

 

Iyakar aikace-aikace

Azurfa oxide shine kayan lantarki don batir oxide na azurfa. Hakanan yana da rauni mai rauni da tushe mai rauni a cikin haɓakar ƙwayoyin cuta, wanda zai iya amsawa tare da 1,3-disubstituted imidazole salts da benzimidazole salts don samar da azenes. Yana iya maye gurbin m ligands kamar cyclooctadiene ko acetonitrile a matsayin carbene canja wurin reagents don hada mika mulki karfe carbene hadaddun. Bugu da ƙari, oxide na azurfa na iya canza kwayoyin bromides da chlorides zuwa barasa a ƙananan yanayin zafi kuma a gaban tururin ruwa. Ana amfani dashi tare da iodomethane azaman methylation reagent don bincike na methylation na sukari da halayen kawar da Hoffman, da kuma iskar oxygenation na aldehydes zuwa acid carboxylic.
