Ukucaciswa

I-sulphur tetrafluoride iyinhlanganisela ye-inorganic ene-molecular formula ye-SF4. Igesi engenambala, edlayo futhi enobuthi kakhulu endaweni ejwayelekile. Inesisindo samangqamuzana angu-108.05, indawo yokuncibilika engu -124°C, kanye nephuzu lokubila elingu -38°C. Kuyi-ejenti esebenza kakhulu futhi esetshenziswa kabanzi ekhethiwe ye-organic fluorinating. Ingakhetha ngokukhetha i-fluorinate carbonyl kanye namaqembu e-hydroxyl. Inesikhundla esingenakushintshwa ekukhiqizeni amakhemikhali amahle, izinto zekristalu ewuketshezi kanye nezimboni zemithi ezisezingeni eliphezulu. I-sulphur tetrafluoride iyi-ejenti ekhethiwe ye-organic fluorinating. Kuyigesi engenambala enephunga elinamandla elifana negesi yesulfure dioxide ngaphansi kwezinga lokushisa elivamile nokucindezela. Inobuthi futhi ayishi noma iqhume emoyeni; ku-600°C Izinzile kakhulu. I-hydrolysis enamandla emoyeni ikhipha intuthu emhlophe. Ukuhlangana nomswakama endaweni kungabangela ukugqwala okufana ne-hydrofluoric acid. I-hydrolyzed ngokuphelele ibe yi-sulphur dioxide ne-hydrofluoric acid, lapho i-hydrolyzed ngokwengxenye, ikhiqiza i-thionyl fluoride enobuthi, kodwa ingamuncwa ngokuphelele isixazululo esiqinile se-alkali ukuze ibe usawoti ongenabuthi nongenabungozi; ingancibilika ku-benzene. I-sulphur tetrafluoride okwamanje iyi-ejenti ekhethayo esebenza kakhulu ye-organic fluorinating esetshenziswa kabanzi. Ingakwazi ukukhetha ngokukhetha i-fluorinate i-carbonyl kanye namaqembu e-hydroxyl (ishintsha umoya-mpilo ezinhlanganisela eziqukethe i-carbonyl); isetshenziswa kakhulu kumakhemikhali amahle wezinto ezisezingeni eliphezulu zekristalu ye-liquid futhi Ukukhiqizwa kwezimboni ezisezingeni eliphezulu zemithi nezibulala-zinambuzane kunendawo engenakushintshwa. Ingasetshenziselwa igesi ye-elekthronikhi, i-chemical vapor deposition, i-ejenti yokwelashwa kwendawo, i-plasma etching eyomile nezinye izici eziningi. Isetshenziswa ku-organic synthesis, iyi-reagent evamile yokwenza ama-fluorocarbons. I-sulphur tetrafluoride igcinwa endaweni yokugcina impahla epholile, enomoya. Kufanele igcinwe ngokuhlukana nama-oxidants, amakhemikhali adliwayo, nezinsimbi ze-alkali, futhi kude nomlilo nemithombo yokushisa.

Isicelo:

① I-ejenti ye-Organic fluorination:
I-ejenti ephumelela kakhulu yokukhetha i-fluorinating isetshenziswa kakhulu ezintweni ezisezingeni eliphakeme ze-liquid crystal kanye nesibulala-zinambuzane esine-fluorine, imithi kanye ne-intermediates; ingasetshenziswa futhi njengegesi ye-electron, i-chemical vapor deposition, i-ejenti yokwelashwa kwendawo, i-etching eyomile, i-plasma nezinye izici.

Iphakheji evamile:

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;
②ISO umenzi wesitifiketi;
③Ukulethwa okusheshayo;
④Umthombo wezinto ezingavuthiwe ozinzile;
⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;
⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;Kungaba yisibopho sethu ukwanelisa izidingo zakho futhi sikukhonze ngempumelelo.
