Octafluorocyclobutane (C4F8)

Sigogi na Fasaha

Octafluorocyclobutane sinadari ne mai sinadarai, wani sinadari ne da aka samo daga cyclobutane mai perfluorinated, kuma dabarar sinadaransa ita ce C4F8. Iskar gas mara launi, mara wari, mara ƙonewa. Yana da kwanciyar hankali kuma ba ya da guba. Idan akwai zafi mai yawa, matsin lamba na ciki na akwati zai ƙaru, kuma za a sami haɗarin fashewa da fashewa. Samfurin konewa (rushewa) hydrogen fluoride ne. Octafluorocyclobutane yana da ƙarfi sosai kuma baya amsawa da wasu abubuwa a ƙarƙashin yanayi na yau da kullun. Ana iya yin jirgin ajiya da amsawar ƙarfe da bakin ƙarfe a 120°C, kuma ana iya amfani da ƙarfe a 175°C. Idan ya wuce 400°C, Kayan Inconel kamar, nickel da platinum suma za su iya lalacewa kaɗan. A 500°C, waɗannan kayan suna da tasirin catalytic akan ruɓewa. A yanayin zafi mai yawa (600°C), octafluorocyclobutane na iya ruɓewa zuwa carbon, carbon tetrafluoride da mahaɗan guba. Octafluorocyclobutane yana da aikace-aikace iri-iri. A cikin 'yan shekarun nan, an yi amfani da shi sosai a matsayin mai sanyaya iska don maye gurbin mahaɗan chlorofluorocarbon da aka haramta. Bugu da ƙari, ana kuma amfani da shi sosai a cikin hanyoyin hana iskar gas, abubuwan narkewa, feshi, wakilai masu kumfa, da manyan abubuwan da ke fitar da iskar gas. , Ruwan famfo mai aiki da kayan aiki don samar da monomers na C2F4 da C3F6. Ana amfani da octafluorocyclobutane mai tsabta (sama da 5N) azaman mai sassaka da mai tsaftacewa don da'irori na VLSI. Saboda halayensa na karko, rashin guba, yuwuwar raguwar ozone (ODP), da ingantaccen rufi, an yi amfani da octafluorocyclobutane sosai a fannoni na fasaha kamar rufin wutar lantarki mai ƙarfi, tsaftacewa da sassaka, da maganin plasma a cikin 'yan shekarun nan. Amsar gaggawa ga zubewa: sanya na'urar numfashi mai zaman kanta da tufafin aiki. Yanke tushen iskar gas. Samun iska da convection, narkewa da yaɗuwa. Matsar da kwantenar da ke zubarwa zuwa wani wuri a buɗe kuma ku kula da iska. Ba za a iya amfani da kwantenar da ke zubarwa ba, kuma dole ne a yi maganin fasaha don cire sauran iskar gas.

Aikace-aikace:

① Masana'antar Abinci:

Ana amfani da shi galibi azaman wakilin feshi a masana'antar abinci, refrigerant.

② Masana'antar Lantarki:

An yi amfani da shi azaman cakuda dielectric tare da sf6, kuma yana taimakawa wajen samar da sinadarai masu amfani da fluoride.
