Pfuma yenyama

Phe chemical formula ye silver oxide ndeye Ag2O, ine huremu hwe 231.74. Brown kana greyish dema rakasimba, ine density ye7.143g/cm, inokurumidza kuora kuita sirivheri uye oxygen pa300 ℃. Inonyungudika zvishoma mumvura, inonyungudika zvakanyanya munitric acid, ammonia, sodium thiosulfate, uye potassium cyanide mhinduro. Kana iyo ammonia solution inoshandiswa, inofanira kurapwa panguva yakakodzera. Kuratidzwa kwenguva refu kunogona kukonzera kuputika kwakanyanya makristasi matema - sirivheri nitride kana sirivheri sulfite. Inoshandiswa se oxidant uye girazi colorant. Yakagadzirirwa nekuita sirivha nitrate mhinduro ine sodium hydroxide mhinduro.

Brown cubic crystalline kana brown black powder. Bond kureba (Ag O) 205pm. Kuora pa250 madhigirii, kuburitsa okisijeni. Density 7.220g/cm3 (25 madhigirii). Chiedza chinoora zvishoma nezvishoma. React ne sulfuric acid kugadzira sirivheri sulfate. Zvishoma soluble mumvura. Soluble mumvura yeammonia, sodium hydroxide solution, dilute nitric acid, uye sodium thiosulfate solution. Insoluble mu ethanol. Yakagadzirirwa nekuita sirivha nitrate mhinduro ine sodium hydroxide mhinduro. Wet Ag2O inoshandiswa sechinhu chinokonzeresa kana ichitsiva halogens nemapoka ehydroxyl mune organic synthesis. Inoshandiswawo sechinhu chekuchengetedza uye chemagetsi mudziyo.

 

Chemical property

Wedzera caustic solution kune sirivheri nitrate solution kuti uiwane. Chekutanga, mhinduro yesirivheri hydroxide uye nitrate inowanikwa, uye sirivheri hydroxide inoora kuita sirivheri oxide uye mvura pane tembiricha. Silver oxide inotanga kuora kana yapiswa kusvika 250 ℃, ichiburitsa okisijeni, uye inokurumidza kuora pamusoro pe300 ℃. Inonyungudika zvishoma mumvura, asi inonyungudika zvakanyanya mumhinduro dzakadai se nitric acid, ammonia, potassium cyanide, uye sodium thiosulfate. Mushure mekuratidzwa kwenguva yakareba kune mhinduro yayo yeammonia, makristasi matema akasimba anoputika anogona dzimwe nguva kunaya - pamwe sirivheri nitride kana sirivharide. Mune organic synthesis, mapoka ehydroxyl anowanzo shandiswa kutsiva halogens kana seoxidants. Inogona zvakare kushandiswa semuvarari muindasitiri yegirazi.

 

Kugadzirira nzira

Silver oxide inogona kuwanikwa nekuita alkali metal hydroxide ne silver nitrate. [1] Mhedzisiro inotanga kuburitsa yakanyanya kusagadzikana sirivheri hydroxide, iyo pakarepo inoora kuti iwane mvura uye sirivheri oxide. Mushure mekugeza mvura, inofanira kuomeswa pasi pe85 ° C, asi zvakaoma zvikuru kubvisa mvura shoma kubva kune sirivheri oxide pakupedzisira nokuti sezvo kutonhora kunowedzera, oxide yesirivha ichaora. 2 Ag+ + 2 OH− → 2 AgOH → Ag2O + H2O.

 

Basic kushandiswa

Inonyanya kushandiswa sechigadziriso chemakemikari synthesis. Inoshandiswawo sekuchengetedza, zvemagetsi mudziyo zvinhu, girazi colorant, uye kugaya mumiririri. Inoshandiswa kune zvekurapa uye segirazi polishing agent, colorant, uye mvura yekuchenesa; Inoshandiswa seye polishing uye coloring agent yegirazi.

 

Application scope

Silver oxide ndiyo electrode zvinhu zvesirivha oxide mabhatiri. Iyo zvakare isina kusimba oxidant uye isina kusimba base mune organic synthesis, inogona kuita ne1,3-disubstituted imidazole munyu uye benzimidazole munyu kugadzira azenes. Iyo inogona kutsiva isina kugadzikana ligands senge cyclooctadiene kana acetonitrile secarbene transfer reagents kuti igadzirise shanduko yesimbi carbene complexes. Uye zvakare, sirivheri oxide inogona kushandura organic bromides uye chlorides kuita madoro pakudziya kwakadzika uye pamberi pehupfu hwemvura. Inoshandiswa pamwe chete neiodomethane semethylation reagent yekuongororwa kweshuga methylation uye Hoffman elimination reactions, pamwe neiyo oxidation yealdehydes kune carboxylic acids.
