Cuab yeej

Phe tshuaj noj cov qauv nyiaj ntawm cov nyiaj oxide yog ag2o, nrog txoj kev molecular hnyav ntawm 231.74. Xim av lossis xim tawv xim dub, nrog lub ntom ntom ntawm 7.143g / cm, nrawm decomposes los ua nyiaj thiab oxygen ntawm 300 ℃. Soluble me ntsis hauv dej, heev soluble hauv nitric acid, ammonia, sodium thiosulfate, thiab poov tshuaj cyathide daws. Thaum lub ammonia kev daws tau siv, nws yuav tsum tau kho kom ncav sijhawm. Kev nthuav tawm ntev ntev tuaj yeem ua ntej nag dawb muaju - nyiaj nitride lossis nyiaj sulfite. Siv ua cov oxidant thiab iav cigrant. Npaj los ntawm reacting nyiaj nitrate cov tshuaj nrog sodium hydrocide tov.

Brown cubic crystalline lossis xim av dub hmoov. Daim ntawv cog lus ntev (AG O) 205 teev tsaus ntuj. Kev txiav txim siab ntawm 250 degrees, tso tawm oxygen. Ntsej Muag 7.220g / CM3 (25 degrees). Lub teeb maj mam decomposes. Hnov mob nrog sulfuric acid los tsim cov nyiaj sulfate. Me ntsis soluble hauv dej. Soluble hauv dej ammogia, sodium hydroxide tov, dilute nitric acid, thiab sodium thiosulfate daws. Insoluble hauv ethanol. Npaj los ntawm reacting nyiaj nitrate cov tshuaj nrog sodium hydrocide tov. Ntub Ag2o yog siv los ua catalyst thaum hloov halogens nrog pawg hydroxyl hauv cov khoom siv organic. Kuj tseem siv los ua cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.

 

Cov cuab yeej tshuaj

Ntxiv cov kev daws teeb meem rau cov nyiaj nitrate kom tau nws. Firstly, kev daws ntawm cov nyiaj hydroxide thiab nitrate tau, thiab nyiaj hydroxide decomposes rau hauv nyiaj oxide thiab dej ntawm chav tsev kub. Nyiaj oxide pib decompose thaum rhuab mus rau 250 ℃, tso cov pa, thiab decompaignes loj tshaj 300 ℃. Soluble me ntsis hauv dej, tab sis soluble nyob rau hauv cov kev daws teeb meem xws li nitric acid, ammonia, potassium cyanide, thiab sodium thiosulfate. Tom qab raug ncua ntev mus rau nws ammonia kev daws, muaj zog tawg dub muaju yuav qee zaum precipitate - tejzaum xyov nyiaj txiag nitride lossis nyiaj txiag iminide. Hauv cov khoom siv hluav taws xob hauv cev, cov pab pawg hydroxyl feem ntau siv los hloov halogens lossis cov tshuaj oxidants. Nws kuj tseem siv tau los ua cov xim hauv kev lag luam iav.

 

Kev npaj txoj kev

Nyiaj oxide tuaj yeem tau txais los ntawm reacting alkali hlau hydroxide nrog nyiaj nitrate. [1] Qhov kev tawm tsam ua ntej tsim cov nyiaj tsis ruaj khov hydroxide, uas tam sim ntawd decomposes kom tau txais dej thiab nyiaj oxide. Tom qab ntxuav cov nag daus, nws yuav tsum tau qhuav nyob rau tsawg dua 85 ° C, tab sis nws nyuaj heev vim tias kub nce ntxiv, qhov nyiaj oxide yuav decompose. 2 AG + + 2 OH- → 2 ag → ag2o + h2o.

 

Kev Siv Khoom Siv Yooj Yim

Mas siv los ua catalyst rau tshuaj synthesis. Nws tseem raug siv los ua cov tshuaj tiv thaiv, cov khoom siv hluav taws xob, iav Colourant, thiab tus neeg sawv cev sib tsoo. Siv rau kev kho mob thiab raws li iav polishing tus neeg sawv cev, cov xim av, thiab dej ua kom huv; Siv los ua polishing thiab xim tus neeg sawv cev rau iav.

 

Daim ntawv thov tau

Nyiaj oxide yog cov khoom hluav taws xob rau cov nyiaj oxide roj teeb. Nws tseem yog ib lub zog oxidant thiab lub hauv paus tsis muaj zog hauv cov synthic synthesis, uas tuaj yeem hnov ​​mob nrog cov ntsev thiab benzimidazole salts kom generate. Nws tuaj yeem hloov chaw tsis ruaj khov xws li cycloctadiene lossis acetonitrile li carbene hloov reagents los synthesize hlau carbene complexes. Ib qho ntxiv, cov nyiaj oxide tuaj yeem hloov kho cov organic bromides thiab chlorides rau hauv cov dej cawv ntawm cov dej kub tsis tshua kub thiab nyob ntawm cov dej vapor. Nws yog siv ua ke nrog iodomethane xws li methylation reagent rau kev tawm tsam methylation thiab Hoffman kev tshem tawm, thiab rau cov oxidation ntawm aldehydes rau carboxylic acids.
