Sulfur tetrafluoride (SF4)

Nkọwapụta

Sulfur tetrafluoride bụ ngwakọta inorganic nwere usoro ihe omimi nke SF4.Ọ bụ gas na-enweghị agba, na-emebi emebi na nke ukwuu na-egbu egbu na gburugburu ọkọlọtọ.Ọ nwere ịdị arọ molekụla nke 108.05, ebe mgbaze nke -124°C, yana ebe esi mmiri -38°C.Ọ bụ ihe kachasị dị irè na nke a na-ejikarị eme ihe n'ụlọnga organic fluorinating nhọrọ.Ọ nwere ike họrọ fluorinate carbonyl na hydroxyl otu.Ọ nwere ọnọdụ na-enweghị atụ na mmepụta nke kemịkalụ dị mma, ihe kristal mmiri mmiri na ụlọ ọrụ ọgwụ dị elu.Sulfur tetrafluoride bụ onye na-ahụ maka fluorinating organic na-ahọrọ.Ọ bụ gas na-enweghị agba nke nwere isi siri ike dị ka sulfur dioxide gas n'okpuru ọnọdụ okpomọkụ na nrụgide nkịtị.Ọ na-egbu egbu ma ọ naghị agba ọkụ ma ọ bụ gbawaa n'ikuku;na 600°C ka kwụsiri ike.Hydrolysis siri ike na ikuku na-ewepụta anwụrụ ọkụ.Izute na mmiri na gburugburu ebe obibi nwere ike ime ka corrosion yiri hydrofluoric acid.A na-etinye ya kpamkpam n'ime sọlfọ dioxide na hydrofluoric acid, mgbe ụfọdụ hydrolyzed, ọ na-emepụta thionyl fluoride na-egbu egbu, ma ọ nwere ike ịbanye kpamkpam site na ngwọta alkali siri ike ịghọ nnu na-adịghị egbu egbu na nke na-adịghị emerụ ahụ;enwere ike igbari ya na benzene.Sulfur tetrafluoride bụ ihe kacha arụ ọrụ nke ọma na-ahọrọ ụdị fluorinat organic nke a na-ejikarị eme ihe.Ọ nwere ike họrọ fluorinate carbonyl na hydroxyl otu (na-anọchi oxygen na carbonyl nwere ogige);a na-eji ya eme ihe na kemịkalụ dị mma maka ihe kristal mmiri dị elu na mmepụta nke ụlọ ọrụ mmepụta ihe na-emepụta ọgwụ na pesticide intermediates nwere ọnọdụ na-enweghị atụ.Enwere ike iji ya maka gas eletrọnịkị, nsị kemịkalụ kemịkalụ, onye na-ahụ maka ọgwụgwọ elu, etching akọrọ plasma na ọtụtụ akụkụ ndị ọzọ.A na-eji ya na njikọ organic, ọ bụ reagent na-emekarị maka ịmepụta fluorocarbons.A na-echekwa Sulfur tetrafluoride n'ụlọ nkwakọba ihe dị jụụ, ikuku ikuku.Ekwesịrị ịchekwa ya iche site na oxidants, kemịkalụ oriri, na ọla alkali, yana pụọ ​​na isi mmalite ọkụ na okpomọkụ.

Ngwa:

① Organic fluorination ihe:
Ndị kasị dị irè elu selectivity fluorinating gị n'ụlọnga na-ọtụtụ ebe na elu-ọkwa mmiri kristal ihe onwunwe na fluorine-nwere pesticides, pharmaceuticals na intermediates;nwekwara ike iji dị ka electron gas, kemịkalụ vapor deposition, elu ọgwụgwọ elekọta mmadụ, akọrọ etching, plasma na akụkụ ndị ọzọ.

Uru:

① Ihe karịrị afọ iri na ahịa;
② onye nrụpụta akwụkwọ ISO;
③ nnyefe ngwa ngwa;
④ Isi iyi akụrụngwa siri ike;
⑤ Usoro nyocha nke ntanetị maka njikwa mma na usoro ọ bụla;
⑥ High chọrọ na usoro nlezianya maka ijikwa cylinder tupu ejuputa;
