Sulfur Tetrafluoride (SF4)

Hōʻike

ʻO ka Sulfur tetrafluoride he pūhui inorganic me kahi ʻano mole o SF4.He kinoea kala ʻole, ʻino a ʻona loa i loko o kahi kaiapuni maʻamau.He 108.05 kona kaumaha mole, he wahi hehee o -124°C, a he wahi paila o -38°C.ʻO ia ka mea ʻoi aku ka maikaʻi a hoʻohana nui ʻia i ka mea hoʻohana fluorinating organik.Hiki iā ia ke koho i nā hui carbonyl a me hydroxyl fluorinate.He kūlana hiki ʻole ke hoʻololi ʻia i ka hana ʻana i nā kemika maikaʻi, nā mea aniani wai a me nā ʻoihana lāʻau lapaʻau kiʻekiʻe.ʻO ka Sulfur tetrafluoride kahi mea hana fluorinating organik koho.He kinoea kala ʻole me ka ʻala ikaika e like me ke kinoea sulfur dioxide ma lalo o ka mahana a me ke kaomi maʻamau.He mea ʻawaʻawa a ʻaʻole e wela a pahū paha i ka lewa;ma 600°C Paʻa loa.ʻO ka hydrolysis ikaika i ka lewa e hoʻopuka i ka uahi keʻokeʻo.ʻO ka loaʻa ʻana o ka makū i loko o kahi kaiapuni hiki ke hoʻomake like me ka waika hydrofluoric.Hoʻopiha piha ʻia i loko o ka sulfur dioxide a me ka waika hydrofluoric, i ka wā i hoʻoheheʻe ʻia i kahi hapa, e hoʻohua ai i ka thionyl fluoride ʻona, akā hiki ke hoʻopili piha ʻia e ka hopena alkali ikaika e lilo i paʻakai ʻona a me ka paʻakai ʻole;hiki ke hoʻoheheʻe ʻia i loko o ka benzene.ʻO Sulfur tetrafluoride i kēia manawa ka mea hoʻohana nui i ka fluorinating organik koho.Hiki iā ia ke koho i nā hui carbonyl a me hydroxyl fluorinate (hoʻololi i ka oxygen i loko o nā pūhui carbonyl);hoʻohana nui ʻia ia i nā kemika maikaʻi no nā mea aniani wai kiʻekiʻe a ʻO ka hana ʻana o nā lāʻau lapaʻau kiʻekiʻe a me nā pesticide ʻoihana waena he kūlana hiki ʻole ke hoʻololi.Hiki ke hoʻohana ʻia no ke kinoea uila, ka hoʻoheheʻe ʻana i ka mahu, ka mea lapaʻau ma luna, ka etching maloʻo plasma a me nā mea ʻē aʻe he nui.Hoʻohana ʻia i ka synthesis organik, he reagent maʻamau no ka hana ʻana i nā fluorocarbons.Mālama ʻia ʻo Sulfur tetrafluoride i loko o kahi hale kūʻai anuanu.Pono e mālama ʻokoʻa ʻia mai nā oxidants, nā kemika hiki ke ʻai, a me nā metala alkali, a ma kahi mamao aku i ke ahi a me nā kumu wela.

① ʻAikena fluorination organik:
Hoʻohana nui ʻia ka mea hoʻohana fluorinating kiʻekiʻe kiʻekiʻe kiʻekiʻe i loko o nā mea aniani wai kiʻekiʻe a me nā pesticides i loko o ka fluorine, nā lāʻau lapaʻau a me nā mea waena;Hiki ke hoʻohana ʻia e like me ke kinoea electron, ka hoʻoheheʻe ʻana i ka mahu, nā mea lapaʻau ma luna, ka etching maloʻo, ka plasma a me nā mea ʻē aʻe.
