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 wai 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 ʻawaʻawa a maikaʻi 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.

Noi:

① ʻAikena fluorination organik:
Hoʻohana nui ʻia ka mea hoʻoheheʻe fluorinating kiʻekiʻe kiʻekiʻe kiʻekiʻe i 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.

④Stable kumu kumu waiwai;
⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;
⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
