Ukuthengisa okushushu kweChina Sulfur Tetrafluoride

Umgangatho Wokuqala, kunye noThengi oPhakamileyo sisikhokelo sethu sokubonelela ngeyona nkxaso ilungileyo kubathengi bethu. Kule mihla, sifuna eyona nkxaso inkulu ukuba sibe ngomnye wabathengisi bangaphandle abaluncedo kwicandelo lethu ukuze sanelise abathengi abangakumbi abathengisa ngokushushu iChina Sulfur Tetrafluoride, Ngayo yonke imfundiso “yosekwe elukholweni, umthengi kuqala”, samkela abathengi ukuba basitsalele umnxeba okanye basitsalele umnxeba.

Kule mihla, sifuna eyona inkulu yethu ukuba ngomnye wabona bathengi bangaphandle baluncedo kwicandelo lethu ukuze sanelise abathengi abaninzi ngakumbi(SF4), Uyilo, ukusetyenzwa, ukuthenga, ukuhlola, ukugcinwa, inkqubo yokuhlanganisa zonke zikwinkqubo yezenzululwazi kunye nesebenzayo yamaxwebhu, ukwandisa inqanaba lokusetyenziswa kunye nokuthembeka kophawu lwethu ngokunzulu, okusenza sibe ngababoneleli abaphezulu kwiindidi ezine zeemveliso ezinkulu zokuphosa ngaphakathi kwaye sifumene ukuthembela komthengi kakuhle.

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, 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.
