Okujwayelekile

Impahla yenyama

Ifomula ye-Phe Chemical formula yesiliva oxide i-Ag2o, ngesisindo samangqamuzana esingu-231.74. Umbala onsundu noma onsundu oqinile oqinile, onobuntu bakwa-7.143g / cm, uphonsa ngokushesha ukwakha isiliva nomoya-mpilo ngo-300 ℃. Shintshana kancane emanzini, ukuncibilika kakhulu ku-nitric acid, i-ammonia, soosulfate, kanye nezixazululo ze-potassium cyanide. Lapho kusetshenziswa isixazululo se-ammonia, kufanele siphathwe ngendlela esifike ngesikhathi. Ukuvezwa isikhathi eside kungacacisa amakristalu amnyama aqhuma kakhulu - isiliva i-nitride noma i-sulfite yesiliva. Isetshenziswa njenge-oxidant nengilazi enombala. Ilungiselelwe ngokusabela kwesiliva i-Nitrate Solution ngeSodium Hydroxide Solution.

Brown cubic crystalline noma i-brown black powder. Ubude bobumba (AG O) 205pm. Ukubola ngamadigri angama-250, kukhulula umoya-mpilo. Ubuningi 7.220g / cm3 (25 degrees). Ukukhanya kancane kancane kuyamdumisa. Baphendule nge-sulfuric acid ukukhiqiza i-sulfate yesiliva. Incibilika kancane emanzini. Sluble e-ammonia amanzi, sodium hydroxide solution, i-dilute nitric acid, kanye ne-soosulfate solution. Insoluble e-ethanol. Ilungiselelwe ngokusabela kwesiliva i-Nitrate Solution ngeSodium Hydroxide Solution. I-Wet AG2O isetshenziswa njenge-catalyst lapho ifaka ama-halogens ngamaqembu we-hydroxyl ku-organic synthesis. Isetshenziswe futhi njengento yokugcina yedivayisi ye-elekthronikhi.

 

Impahla yamakhemikhali

Faka isixazululo se-caustic kwikhambi lesiliva nitrate ukuze uthole. Okokuqala, isixazululo se-streer hydroxide kanye ne-nitrate siyatholakala, kanti iziliva ze-hydroxide zibola nge-oxide namanzi egumbini lokushisa. Isiliva oxide iqala ukubola lapho kufuthelwa ku-250 ℃, kukhulula umoya-mpilo, futhi kukhale ngokushesha ngenhla kwama-300 ℃. Shintshana kancane emanzini, kepha kuyancibilika kakhulu ngezixazululo ezinjenge-nitric acid, i-ammonia, i-potassium cyanide, ne-sodium thiesulfate. Ngemuva kokuvezwa isikhathi eside kusixazululo sayo se-ammonia, amakristalu amnyama aqhumayo ngesinye isikhathi angahle anciphise - mhlawumbe i-nitride yesiliva noma iliminide yesiliva. Ekuhlolweni kwe-organic, amaqembu e-hydroxyl ajwayele ukusetshenziselwa ukumiselela ama-halogens noma njenge-oxidants. Ingasetshenziswa futhi njengombala onemibala embonini yengilazi.

 

Indlela yokulungiselela

I-Spreen Oxide ingatholakala ngokuphendula i-Alkali Metal Hydroxide nge-nitrate yesiliva. . Ngemuva kokugeza i-precipitate, kufanele yomiswe ngaphansi kwama-85 ° C, kodwa kunzima kakhulu ukususa inani elincane lamanzi kusuka kwi-oxide yesiliva ekugcineni ngoba izinga lokushisa likhuphuka. 2 AG + + 2 Oh- → → 2 ANOH → AG2O + H2O.

 

Ukusetshenziswa okuyisisekelo

Isetshenziswa ikakhulukazi njenge-catalyst ye-synthes yamakhemikhali. Iphinde isetshenziswe njengento yokugcina, impahla yedivayisi ye-elekthronikhi, onombala wengilazi, kanye ne-ejenti yokugaya. Isetshenziselwe izinhloso zokwelashwa futhi njenge-ejenti yokupholisa ingilazi, onemibala, kanye nehlazo lamanzi; Isetshenziswa njenge-ejenti yokupholisa kanye nombala engilazi.

 

Isikali sohlelo

Isiliva oxide iyinto esetshenziswa nge-electrode yamabhethri we-oxide we-spreen oxide. Kubuye kube yi-oxidant ebuthakathaka nesisekelo esibuthakathaka ekuhlolweni kwe-organic, okungasabela ngosawoti we-Imidazole ongu-1,3-Dissubstitated kanye nosawoti we-benzimidazole ukukhiqiza aberes. Ingathatha indawo engazinzile ama-ligands anjenge-cyclooctadiene noma i-acetonitritle njenge-carbene yokudlulisa ama-reagents ukuvumelanisa izakhiwo ze-carbene zensimbi. Ngaphezu kwalokho, i-Scip Silver Oxide ingaguqula ama-organic bromides kanye nama-chlorides abe utshwala emazingeni okushisa aphansi nasebukhoneni bukaphunga lwamanzi. Isetshenziswa ngokubambisana ne-Iodomethane njenge-realent ye-methylation yokuhlaziywa kwe-sugar methylation kanye ne-hoffman ukusabela, kanye ne-oxidation of Aldehydes kuma-carboxylic acid.
