Sulfur tetrafluoride yog cov tshuaj inorganic nrog cov qauv molecular ntawm SF4. Nws yog cov xim tsis muaj xim, xeb thiab muaj cov pa lom ntau nyob hauv ib puag ncig tus qauv. Nws muaj lub cev hnyav ntawm 108.05, lub ntsiab lus yaj ntawm -124 ° C, thiab lub ntsiab lus kub ntawm -38 ° C. Nws yog qhov ua tau zoo tshaj plaws thiab dav siv xaiv cov tshuaj fluorinating organic. Nws tuaj yeem xaiv cov tshuaj fluorinate carbonyl thiab hydroxyl pawg. Nws muaj txoj haujlwm tsis tuaj yeem hloov pauv hauv kev tsim cov tshuaj zoo, cov khoom siv ua kua thiab cov khoom lag luam kws kho mob siab. Sulfur tetrafluoride yog xaiv cov tshuaj fluorinating organic. Nws yog cov pa roj tsis muaj xim nrog cov ntxhiab tsw zoo ib yam li cov pa roj carbon dioxide nyob hauv qhov kub thiab txias. Nws yog tshuaj lom thiab tsis hlawv lossis tawg hauv huab cua; ntawm 600 ° C Tseem ruaj khov heev. Muaj zog hydrolysis nyob rau hauv cov huab cua tso pa dawb. Ntsib nrog cov dej noo hauv ib puag ncig tuaj yeem ua rau xeb zoo ib yam li hydrofluoric acid. Ua kom tiav hydrolyzed rau sulfur dioxide thiab hydrofluoric acid, thaum ib nrab hydrolyzed, nws tsim cov tshuaj lom thionyl fluoride, tab sis nws tuaj yeem nqus tau tag nrho los ntawm cov tshuaj muaj zog alkali los ua cov tsis muaj tshuaj lom thiab tsis ua rau ntsev; nws tuaj yeem yaj hauv benzene. Sulfur tetrafluoride tam sim no yog qhov ua tau zoo tshaj plaws xaiv cov tshuaj fluorinating tus neeg sawv cev siv dav. Nws tuaj yeem xaiv fluorinate carbonyl thiab hydroxyl pawg (hloov cov pa hauv carbonyl-muaj cov sib xyaw); nws tau siv dav hauv cov tshuaj zoo rau cov khoom siv ua kua ua kua siab kawg thiab Kev tsim khoom lag luam qib high-end kws tshuaj thiab tshuaj tua kab muaj cov haujlwm nruab nrab tsis tuaj yeem hloov pauv tau. Nws kuj tseem tuaj yeem siv rau cov pa hluav taws xob, tso pa tshuaj lom, tus neeg sawv cev kho mob, ntshav qhuav qhuav thiab ntau lwm yam. Siv cov organic sib txuas, nws yog ib qho tshuaj reagent rau ua cov tshuaj fluorocarbons. Sulfur tetrafluoride tau khaws cia rau hauv qhov chaw txias, qhov chaw tso pa tawm. Nws yuav tsum tau khaws cia cais los ntawm cov tshuaj oxidants, tshuaj lom neeg noj tau, thiab alkali hlau, thiab nyob deb ntawm hluav taws thiab cua sov.

Daim ntawv thov:

Agent Tus neeg sawv cev tshuaj fluorination:
Qhov ua tau zoo tshaj plaws xaiv tus neeg sawv cev fluorinating yog siv dav hauv qib qib cov khoom siv ua kua thiab cov tshuaj muaj tshuaj fluorine muaj tshuaj, tshuaj thiab tshuaj nruab nrab; kuj tseem tuaj yeem siv ua hluav taws xob hluav taws xob, tso pa tshuaj lom neeg, cov tshuaj kho saum npoo av, qhuav qhuav, ntshav thiab lwm yam
