Igesi entsha enobungani nemvelo i-Perfluoroisobutyronitrile C4F7N ingathatha indawo ye-sulfur hexafluoride SF6

Njengamanje, iningi lemidiya yokushisa ye-GIL lisebenzisaIgesi le-SF6, kodwa igesi ye-SF6 inomphumela oqinile wokushisa komhlaba (i-coefficient yokufudumala komhlaba i-GWP ingu-23800), inomthelela omkhulu emvelweni, futhi ibhalwe njengegesi yokushisa umhlaba enqunyelwe emhlabeni jikelele. Eminyakeni yamuva nje, izindawo ezishisayo zasekhaya nezakwamanye amazwe zigxile ocwaningweni lweSF6amagesi ahlukile, njengokusetshenziswa komoya ocindezelwe, igesi exubile ye-SF6, kanye namagesi amasha anobungani nemvelo njenge-C4F7N, c-C4F8, CF3I, kanye nokuthuthukiswa kwe-GIL enobungani nemvelo ukuthuthukisa izinzuzo zemvelo zemishini. Kodwa-ke, ubuchwepheshe be-GIL obungabungani nemvelo busesebusha. Ukusetshenziswa kweIgesi exubile ye-SF6noma igesi enobungani nemvelo engena-SF6 ngokuphelele, ukuthuthukiswa kwemishini enamandla kagesi aphezulu, kanye nokukhuthazwa kwegesi enobungani nemvelo emishinini kagesi nakwezinye ubuchwepheshe konke kudinga ukuhlola okujulile nocwaningo.

I-Perfluoroisobutyronitrile, eyaziwa nangokuthi i-heptafluoroisobutyronitrile, inefomula yamakhemikhali ethiC4F7Nfuthi iyinhlanganisela yezinto eziphilayo. I-Perfluoroisobutyronitrile inezinzuzo zokuzinza okuhle kwamakhemikhali, ukumelana nokushisa okuphansi, ukuvikelwa kwemvelo okuluhlaza, iphuzu lokuncibilika eliphezulu, ukuguquguquka okuphansi, kanye nokuvikela okuhle. Njengendawo yokuvikela imishini kagesi, inamathuba amaningi okusetshenziswa emkhakheni wezinhlelo zamandla.

Esikhathini esizayo, ngokusheshiswa kokwakhiwa kwamaphrojekthi e-UHV ezweni lakithi, ukuchuma kwemboni ye-perfluoroisobutyronitrile kuzoqhubeka nokuthuthuka. Ngokuphathelene nokuncintisana emakethe, izinkampani zaseShayina zinamandla okukhiqiza ngobuningi.i-perfluoroisobutyronitrileEsikhathini esizayo, ngokuthuthuka kobuchwepheshe kanye nokuthuthuka okuqhubekayo kwezindinganiso zemboni, isabelo semakethe semikhiqizo esezingeni eliphezulu sizoqhubeka nokukhula.
