Sarufa Tetrafluoride (SF4)

Tsanangudzo

Sulfur tetrafluoride chinhu chisina kuchena chine fomura yemamorekuru yeSF4. Igasi risina ruvara, rinoparadza uye rine chepfu yakawanda munzvimbo yakajairika. Rine huremu hwemamorekuru hwe108.05, nzvimbo yekunyunguduka ye -124°C, uye nzvimbo yekufashaira ye -38°C. Ndiyo inonyanya kushanda uye inoshandiswa zvakanyanya mukusarudza organic fluorinating agent. Inogona kusarudza fluorinating carbonyl ne hydroxyl groups. Ine nzvimbo isingatsivike mukugadzirwa kwemakemikari akanaka, zvinhu zve liquid crystal uye maindasitiri emishonga epamusoro. Sulfur tetrafluoride imhando ye organic fluorinating agent. Igasi risina ruvara rine hwema hwakasimba hwakafanana negasi re sulfur dioxide pasi pekupisa kwakajairika nekumanikidzwa. Rine chepfu uye haripisi kana kuputika mumhepo; pa600°C Richiri rakagadzikana. Hydrolysis yakasimba mumhepo inoburitsa utsi huchena. Kusangana nehunyoro munzvimbo kunogona kukonzera ngura yakafanana ne hydrofluoric acid. Yakanyungudutswa zvizere kuita sarufa dioxide uye hydrofluoric acid, kana ikanyungudutswa zvishoma, inogadzira thionyl fluoride ine chepfu, asi inogona kunyungudutswa zvachose nealkali solution yakasimba kuti ive munyu usina chepfu uye usingakuvadzi; inogona kunyungudutswa mubenzene. Sulfur tetrafluoride parizvino ndiyo inonyanya kushandiswa mu organic fluorinating agent. Inogona kusarudza fluorinating carbonyl ne hydroxyl groups (ichitsiva oksijeni mu carbonyl-containing compounds); inoshandiswa zvakanyanya mumakemikari akanaka emhando yepamusoro ye liquid crystal materials uye Kugadzirwa kwemishonga yepamusoro-soro uye mishonga yezvipembenene ine nzvimbo isingatsiviwi. Inogona zvakare kushandiswa kune electronic gas, chemical vapor deposition, surface treatment agent, plasma dry etching nezvimwe zvinhu zvakawanda. Inoshandiswa mu organic synthesis, i reagent yakajairika yekugadzira fluorocarbons. Sulfur tetrafluoride inochengetwa mu warehouse inotonhorera, ine mhepo. Inofanira kuchengetwa yakasiyana ne oxidants, edible chemicals, uye alkali metals, uye kure nemoto nekupisa.

Kushandiswa:

① Mushonga we fluorination we organic:
Mushonga unoshanda zvakanyanya wekusarudza fluorinating unoshandiswa zvakanyanya muzvinhu zvemhando yepamusoro zvemakristaro emvura uye mishonga yekuuraya zvipembenene ine fluorine, mishonga yemishonga uye yepakati; inogona zvakare kushandiswa segasi remaerekitironi, makemikari evapor deposition, mishonga yekurapa pamusoro, dry etching, plasma nezvimwe zvinhu.

Pakeji yakajairika:

Zvakanakira:

①Makore anopfuura gumi ari pamusika;
②Mugadziri wezvitupa zveISO;
③Kutumira nekukurumidza;
④Manyuko ezvinhu zvakabikwa akagadzikana;
⑤Sisitimu yekuongorora yepamhepo yekudzora mhando padanho rega rega;
⑥Kushandiswa kwakawanda uye kwakanyatsorongwa kwekubata silinda usati wazadza;
