I-Sulphur tetrafluoride iyinhlanganisela engaphili enefomula ye-SF4. Igesi elingenambala, elonakalisayo nelinobuthi obukhulu endaweni ejwayelekile. Inesisindo samangqamuzana esingu-108.05, indawo encibilikayo engu -124 ° C, nendawo yokubilisa engu -38 ° C. Kuyinto ekhetha kakhulu futhi esetshenziswa kakhulu ekhethiwe ejwayelekile yokwenza i-organic fluorinating. Ingakhetha ngokukhetha ukugcoba ama-carbonyl namaqembu e-hydroxyl. Inesikhundla esingabuyiseki ekukhiqizeni amakhemikhali amahle, izinto zekristalu eziwuketshezi nezimboni zemithi ephezulu. Isulfure tetrafluoride iyinhlangano ekhetha i-organic fluorinating agent. Kuyinto igesi engenambala enephunga elinamandla elifana negesi yesulfure dioxide ngaphansi kwezinga lokushisa nokucindezela okujwayelekile. Inobuthi futhi ayishisi noma iqhume emoyeni; ngo-600 ° C Kusazinzile kakhulu. I-hydrolysis enamandla emoyeni ikhipha intuthu emhlophe. Ukuhlangana nomswakama endaweni kungadala ukugqwala okufana ne-hydrofluoric acid. I-hydrolyzed ngokuphelele ibe yi-sulfur dioxide ne-hydrofluoric acid, lapho i-hydrolyzed ngokwengxenye, ikhiqiza i-thionyl fluoride enobuthi, kepha ingamunceka ngokuphelele yisisombululo esinamandla se-alikhali ukuze ibe usawoti ongenabuthi futhi ongenabungozi; ingaqedwa nge-benzene. I-Sulphur tetrafluoride njengamanje iyisetshenziswa esisebenza kakhulu se-organic fluorinating esetshenziswa kabanzi. Kungakhetha ngokukhetha ukugcoba ama-carbonyl namaqembu e-hydroxyl (ukufaka i-oxygen kumakhemikhali aqukethe i-carbonyl); isetshenziswa kabanzi kumakhemikhali amahle ngezinto ezisezingeni eliphezulu ezikhiqiza uketshezi futhi Ukukhiqizwa kwezindawo eziphakeme zezimboni zemithi kanye nezibulala-zinambuzane kunesikhundla esingabuyiseka. Ingasetshenziselwa igesi kagesi, ukufakwa kwamaphemikhali, i-ejenti yokwelashwa ebusweni, i-plasma eyomile kanye nezinye izici eziningi. Isetshenziswe ekuhlanganisweni kwezinto eziphilayo, kuyisenzo esivamile sokwenza ama-fluorocarbon. I-Sulphur tetrafluoride igcinwa endaweni epholile, yokugcina umoya. Kufanele igcinwe ngokwehlukile kuma-oxidants, amakhemikhali adliwayo, nezinsimbi ze-alkali, futhi kude nomthombo womlilo nokushisa.

Isicelo:

Agent Umenzeli we-organic fluorination:
I-ejenti esebenza kahle kakhulu yokukhetha okokuhluza okusetshenziswa kakhulu isetshenziswa kakhulu ebangeni eliphakeme le-liquid crystal material kanye ne-pesticides equkethe i-pesticides, imithi yokwelapha kanye nabaxhumanisi; Ingasetshenziswa futhi njengegesi ye-elektroni, ukufakwa kwamaphemikhali amakhemikhali, ama-ejenti okwelashwa ngaphezulu, ukudonswa okwomile, i-plasma nezinye izici
