He utu whakaheke nui kei Haina, he kounga teitei te kounga o te hau motuhake o te karaehe ahumahi, he hau tetrafluoride sf4.

Ko tā mātou rapunga whakaaro pakihi he waihanga i ngā hua nui ake mō ngā kaihoko; ko te whakatipu kiritaki tā mātou whainga matua mō ngā utu whakaheke nui e tukuna ana e Haina, he hau motuhake kounga teitei mō te Sulfur Tetrafluoride Sf4, kei te rapu mātou i ngā hononga pai me te whai hua ki ngā ratonga katoa o te ao. E mihi ana mātou ki a koe kia whakapā mai ki a mātou ki te tīmata kōrero mō te huarahi e taea ai e mātou te whakatutuki i tēnei.
Ko tā mātou rapunga whakaaro pakihi he waihanga i ngā painga nui ake mō ngā kaihoko; ko te whakatipu kiritaki tā mātou whāinga matuaHaina Tetrafluoride Whāriki Sf4 me te Tetrafluoride Whāriki, E tohe ana tā mātou wheketere ki te kaupapa "Kounga Tuatahi, Whakawhanake Tauwhiro", ā, e whai ana i te "Pakihi Pono, Ngā Painga Tauutuutu" hei whāinga whanaketanga mā mātou. E mihi nui ana ngā mema katoa ki te tautoko a ngā kiritaki tawhito me ngā kiritaki hou. Ka kaha tonu tā mātou mahi me te tuku atu i ngā otinga me ngā ratonga kounga teitei ki a koe. Ngā mihi.

Whakatakotoranga

Ko te whanariki tetrafluoride he matū kore-waro, ko tōna tauira ngota ko te SF4. He hau kore tae, he waikura, he tino paitini hoki i roto i te taiao paerewa. Ko tōna taumaha ngota he 108.05, ko tōna ira rewa he -124°C, ā, ko tōna ira kohua he -38°C. Koinei te kaihopu whakapūhau waro whiriwhiri tino whai hua, ā, e whakamahia whānuitia ana. Ka taea e ia te whakapūhau i ngā rōpū carbonyl me te hydroxyl. He tūranga nui tōna i roto i te hanga matū pai, ngā rauemi tioata wai me ngā ahumahi rongoā teitei. Ko te whanariki tetrafluoride he kaihopu whakapūhau waro whiriwhiri. He hau kore tae, he kakara kaha rite ki te hau whanariki hauhā i raro i te pāmahana me te pēhanga noa. He paitini, ā, kāore e tahuna, e pahū rānei i te hau; i te 600°C. He tino pumau tonu. Ko te waikura kaha i te hau ka puta he paoa ma. Ki te tūtaki ki te makuku i roto i te taiao, ka taea te waikura rite ki te waikawa hydrofluoric. Ka waikura katoatia hei hauhā whanariki me te waikawa hauwaiwai, ina waikurahia tetahi wāhanga, ka puta he thionyl fluoride paitini, engari ka taea te mimiti katoa e te otinga alkali kaha hei tote kore-paitini, kore-kino hoki; ka taea te rewa ki te benzene. Ko te whanariki tetrafluoride te kaihoko fluorinating waro tino whai hua e whakamahia whānuitia ana i tēnei wā. Ka taea e ia te fluorinating i ngā rōpū carbonyl me te hydroxyl (te whakakapi i te hāora i roto i ngā matū kei roto he carbonyl); ka whakamahia whānuitia i roto i ngā matū pai mō ngā rauemi tioata wai kounga teitei, ā, ko te hanga o ngā takawaenga ahumahi rongoā me ngā patu pepeke kounga teitei he tūranga kore e taea te whakakapi. Ka taea hoki te whakamahi mō te hau hiko, te whakatakotoranga kohu matū, te kaihoko maimoatanga mata, te whakairo maroke plasma me te maha atu o ngā āhuatanga. I te whakamahinga o te hanganga waro, he matū noa mō te hanga fluorocarbons. Ka rongoa te whanariki tetrafluoride ki roto i te whare putunga hauhautanga, hauhautanga. Me rongoa motuhake mai i ngā waikura, ngā matū kai, me ngā konganuku alkali, me te matara atu i ngā puna ahi me te wera.

Taupānga:

① Kaihoko whakapūoro waro:
Ko te kaihoko fluorinating tino whai hua he mea whakamahi whānuitia i roto i ngā rauemi karaihe wai kounga teitei me ngā patu pepeke kei roto te fluorine, ngā rongoā me ngā takawaenga; ka taea hoki te whakamahi hei hau irahiko, hei whakatakotoranga kohu matū, hei kaihoko maimoatanga mata, hei whakairo maroke, hei plasma me ētahi atu āhuatanga.
