Inkcazo

I-sulphur tetrafluoride yi-inorganic compound ene-molecular formula ye-SF4.Yirhasi engenambala, edlekayo kwaye inetyhefu kakhulu kwindawo esemgangathweni.Inobunzima be-molecular 108.05, indawo yokunyibilika -124 ° C, kunye neqondo lokubila elingu -38 ° C.Yeyona arhente isebenzayo kwaye isetyenziswa ngokubanzi ekhethiweyo ye-organic fluorinating.Inokukhetha i-fluorinate ye-carbonyl kunye namaqela e-hydroxyl.Inendawo engenakubuyiselwa ekuvelisweni kweekhemikhali ezintle, imathiriyeli yekristale engamanzi kunye namashishini amayeza akumgangatho ophezulu.I-sulphur tetrafluoride yinto ekhethiweyo ye-organic fluorinating agent.Yigesi engenambala kunye nevumba elinamandla elifana negesi yesulfure dioxide phantsi kobushushu obuqhelekileyo kunye noxinzelelo.Inetyhefu kwaye ayitshi okanye iqhume emoyeni;kwi-600 ° C Isezinzile kakhulu.I-hydrolysis enamandla emoyeni ikhupha umsi omhlophe.Ukudibana nokufuma kwimekobume kunokubangela ukubola okufana ne-hydrofluoric acid.I-hydrolyzed ngokupheleleyo kwi-sulphur dioxide kunye ne-hydrofluoric acid, xa i-hydrolyzed ngokuyinxenye, ivelisa i-thionyl fluoride eyityhefu, kodwa inokufunxwa ngokupheleleyo sisicombululo se-alkali esinamandla ukuba sibe yityuwa engenabungozi kwaye engenabungozi;inokunyibilika kwibenzene.I-sulphur tetrafluoride okwangoku yeyona arhente isebenzayo ekhethiweyo ye-organic fluorinating esetyenziswa ngokubanzi.Iyakwazi ukukhetha i-fluorinate i-carbonyl kunye namaqela e-hydroxyl (ukutshintsha i-oksijini kwi-carbonyl-containing compounds);isetyenziswa kakhulu kwiikhemikhali ezilungileyo zezixhobo zekristale zolwelo eziphezulu kwaye Ukuveliswa kwamayeza aphakathi kwamayeza kunye nezibulali-zinambuzane kunendawo engenakubuyiselwa.Ingasetyenziselwa igesi ye-elektroniki, ukubekelwa umphunga wekhemikhali, iarhente yonyango lomphezulu, iplasma eyomileyo kunye neminye imiba emininzi.Isetyenziswe kwi-organic synthesis, yinto eqhelekileyo yokwenza i-fluorocarbons.Isulphur tetrafluoride igcinwa kwindawo epholileyo nengena umoya.Kufuneka igcinwe ngokwahlukileyo kwii-oxidants, iikhemikhali ezidliwayo, kunye neentsimbi zealkali, kwaye kude nomlilo kunye nemithombo yobushushu.
