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, ukubekwa komphunga 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.
Isicelo:
① Umenzeli we-Organic fluorination:
Eyona ndlela iphezulu yokukhetha i-fluorinating agent isetyenziswa ngokubanzi kwi-high-grade liquid crystal material kunye ne-fluorine ene-pesticides, i-pharmaceuticals kunye ne-intermediates; Inokusetyenziswa njengerhasi ye-electron, ukubekelwa umphunga wekhemikhali, iiarhente zokunyanga umphezulu, ukubetha okomileyo, iplasma kunye neminye imiba.
