Sulfur Tetrafluoride (SF4)

Specification

Sulfur tetrafluoride yog ib qho inorganic compound nrog cov mis molecular ntawm SF4. Nws yog xim tsis muaj xim, corrosive thiab muaj kuab lom heev hauv ib puag ncig tus qauv. Nws muaj qhov hnyav molecular ntawm 108.05, melting point ntawm -124 ° C, thiab boiling point ntawm -38 ° C. Nws yog qhov zoo tshaj plaws thiab siv dav siv cov organic fluorinating tus neeg sawv cev. Nws tuaj yeem xaiv fluorinate carbonyl thiab hydroxyl pawg. Nws muaj txoj haujlwm irreplaceable nyob rau hauv zus tau tej cov tshuaj zoo, kua siv lead ua cov ntaub ntawv thiab high-end kws industries. Sulfur tetrafluoride yog ib qho kev xaiv organic fluorinating tus neeg sawv cev. Nws yog cov roj tsis muaj xim uas muaj ntxhiab tsw zoo ib yam li cov roj sulfur dioxide nyob rau hauv qhov kub thiab txias. Nws yog tshuaj lom thiab tsis hlawv lossis tawg hauv huab cua; ntawm 600 ° C Tseem ruaj khov heev. Vigorous hydrolysis nyob rau hauv cov huab cua emissions dawb pa luam yeeb. Kev ntsib nrog cov dej noo hauv ib puag ncig tuaj yeem ua rau corrosion zoo ib yam li hydrofluoric acid. Ua tiav hydrolyzed rau hauv 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 alkali muaj zog los ua cov ntsev tsis muaj tshuaj lom thiab tsis muaj mob; Nws tuaj yeem yaj hauv benzene. Sulfur tetrafluoride tam sim no yog qhov zoo tshaj plaws xaiv cov organic fluorinating tus neeg sawv cev dav siv. Nws tuaj yeem xaiv cov fluorinate carbonyl thiab hydroxyl pawg (hloov cov pa hauv carbonyl-muaj cov sib txuas); nws yog dav siv nyob rau hauv cov tshuaj zoo rau high-end kua siv lead ua cov ntaub ntawv thiab zus tau tej cov high-end kws tshuaj thiab tshuaj tua kab muaj intermediates muaj ib tug irreplaceable txoj hauj lwm. Nws kuj tseem siv tau rau cov roj hluav taws xob, tshuaj vapor deposition, tus neeg sawv cev kho deg, plasma qhuav etching thiab ntau lwm yam. Siv nyob rau hauv cov organic synthesis, nws yog ib qho reagent rau ua fluorocarbons. Sulfur tetrafluoride yog khaws cia rau hauv qhov chaw txias, qhov cua txias. Nws yuav tsum tau muab cais tawm ntawm oxidants, edible chemicals, thiab alkali hlau, thiab deb ntawm hluav taws kub thiab kub qhov chaw.

Daim ntawv thov:

① Organic fluorination tus neeg sawv cev:
Qhov zoo tshaj plaws kev xaiv fluorinating tus neeg saib xyuas yog siv dav hauv cov khoom siv ua kua siv lead ua qib siab thiab cov tshuaj fluorine uas muaj tshuaj tua kab, tshuaj thiab cov tshuaj nruab nrab; Nws kuj tseem tuaj yeem siv los ua cov pa hluav taws xob, tshuaj vapor deposition, tshuaj kho deg, qhuav etching, plasma thiab lwm yam.
