Sulfur Tetrafluoride (SF4)

Cov Lus Qhia Tshwj Xeeb

Sulfur tetrafluoride yog ib qho inorganic compound nrog cov mis molecular ntawm SF4. Nws yog ib qho roj tsis muaj xim, corrosive thiab muaj kuab lom heev hauv ib puag ncig ib txwm muaj. Nws muaj qhov hnyav molecular ntawm 108.05, lub ntsiab lus yaj ntawm -124 ° C, thiab lub ntsiab lus kub ntawm -38 ° C. Nws yog tus neeg sawv cev xaiv cov organic fluorinating zoo tshaj plaws thiab siv dav tshaj plaws. Nws tuaj yeem xaiv cov fluorinate carbonyl thiab hydroxyl pawg. Nws muaj qhov chaw tseem ceeb hauv kev tsim cov tshuaj zoo, cov ntaub ntawv siv lead ua kua thiab kev lag luam tshuaj siab. Sulfur tetrafluoride yog tus neeg sawv cev xaiv cov organic fluorinating. Nws yog ib qho roj tsis muaj xim nrog lub ntxhiab tsw zoo ib yam li cov roj sulfur dioxide hauv qab qhov kub thiab siab ib txwm muaj. Nws yog tshuaj lom thiab tsis hlawv lossis tawg hauv huab cua; ntawm 600 ° C Tseem ruaj khov heev. Kev hydrolysis hnyav hauv huab cua tso pa dawb. Ntsib nrog dej noo hauv ib puag ncig tuaj yeem ua rau xeb zoo ib yam li hydrofluoric acid. Nws hydrolyzed tag nrho rau hauv sulfur dioxide thiab hydrofluoric acid, thaum hydrolyzed ib feem, nws tsim cov tshuaj lom thionyl fluoride, tab sis nws tuaj yeem nqus tau tag nrho los ntawm cov kua alkali muaj zog kom ua cov ntsev tsis muaj tshuaj lom thiab tsis muaj teeb meem; nws tuaj yeem yaj rau hauv benzene. Sulfur tetrafluoride tam sim no yog tus neeg sawv cev fluorinating organic zoo tshaj plaws uas siv dav. Nws tuaj yeem xaiv fluorinate carbonyl thiab hydroxyl pawg (hloov cov pa oxygen hauv cov tshuaj carbonyl); nws yog siv dav hauv cov tshuaj zoo rau cov khoom siv siv lead ua kua siab thiab Kev tsim cov tshuaj kho mob siab thiab tshuaj tua kab mob muaj qhov chaw tsis hloov pauv. Nws kuj tseem tuaj yeem siv rau cov roj hluav taws xob, cov pa tshuaj tso tawm, cov neeg sawv cev kho qhov chaw, plasma qhuav etching thiab ntau lwm yam. Siv rau hauv cov organic synthesis, nws yog ib qho reagent rau kev ua fluorocarbons. Sulfur tetrafluoride khaws cia rau hauv qhov chaw txias, cua nkag. Nws yuav tsum khaws cia cais ntawm cov oxidants, cov tshuaj noj tau, thiab cov hlau alkali, thiab deb ntawm hluav taws thiab cua sov.

Daim Ntawv Thov:

① Tus neeg sawv cev fluorination organic:
Tus neeg sawv cev fluorinating zoo tshaj plaws yog siv dav hauv cov khoom siv ua kua siv lead ua kua thiab cov tshuaj tua kab uas muaj fluorine, tshuaj thiab cov khoom nruab nrab; kuj tseem siv tau ua roj hluav taws xob, tshuaj lom neeg tso pa tawm, cov neeg sawv cev kho qhov chaw, etching qhuav, plasma thiab lwm yam.
