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 fluoriate carbonyl na hydroxyl otu. Ọ nwere ọnọdụ na-enweghị atụ na mmepụta nke ezigbo kemịkal, 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 akụkụ nke hydrolyzed, ọ na-emepụta thionyl fluoride na-egbu egbu, ma ọ nwere ike ịmịnye ya 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-ejikarị ya eme ihe na kemịkal dị mma maka ihe kristal mmiri dị elu na mmepụta nke ụlọ ọrụ mmepụta ihe dị elu 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-eji na elu-ọkwa mmiri mmiri kristal ihe 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.
