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;I-Quality Initial, kanye ne-Shopper Supreme iyisiqondiso sethu sokunikeza ukwesekwa okungcono kakhulu kubathengi bethu.Namuhla, sifuna okukhulu kunakho konke ukuba omunye wabathumeli bangaphandle abanenzuzo kakhulu emkhakheni wethu ukuze sanelise amakhasimende isidingo esikhulu kakhulu se-Hot-selling China Sulfur. I-Tetrafluoride, Ngayo yonke imfundiso “yokusekelwe okholweni, ikhasimende kuqala”, samukela abathengi ukuthi bavele basishayele noma basithumele i-imeyili ukuze sibambisane.
Ukudayiswa okushisayo(SF4), Idizayini, ukucubungula, ukuthenga, ukuhlola, ukugcinwa, inqubo yokuhlanganisa konke kusenqubweni yemibhalo yesayensi nephumelelayo, ukwandisa izinga lokusetshenziswa nokuthembeka komkhiqizo wethu ngokujulile, okusenza sibe abahlinzeki abaphakeme bezigaba ezine zemikhiqizo emikhulu yokusakazwa kwamagobolondo ekhaya futhi etholiwe. ukwethenjwa kwekhasimende kahle.
