Mawu Oyamba
Dibromodifluoromethane (CBr2F2), yomwe imadziwikanso kuti halothane (halothane, trifluoromethyl bromide), ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dibromodifluoromethane:
Ubwino:
- Maonekedwe: Madzi opanda mtundu
- Kusungunuka: kusungunuka mu ethanol, ether ndi chloride, kusungunuka pang'ono m'madzi
- Kawopsedwe: ali ndi mankhwala ochititsa dzanzi ndipo angayambitse kupsinjika kwapakati pamanjenje
Gwiritsani ntchito:
- Mankhwala Oletsa Kupweteka: Dibromodifluoromethane, yomwe poyamba inkagwiritsidwa ntchito kwambiri m'mitsempha ndi mankhwala oletsa ululu, tsopano yalowetsedwa ndi mankhwala apamwamba kwambiri komanso otetezeka.
Njira:
Kukonzekera kwa dibromodimomethane kungachitike ndi izi:
Bromine imakhudzidwa ndi fluorine pa kutentha kwambiri kuti ipereke fluorobromide.
Fluorobromide imayendetsedwa ndi methane pansi pa cheza cha ultraviolet kupanga dibromodifluoromethane.
Zambiri Zachitetezo:
- Dibromodifluoromethane ili ndi mankhwala ogonetsa ndipo iyenera kugwiritsidwa ntchito mosamala, makamaka popanda chitsogozo cha akatswiri.
- Kuwonetsedwa kwa nthawi yayitali kwa dibromodifluoromethane kumatha kukhala ndi zotsatira zoyipa pachiwindi.
- Zitha kuyambitsa mkwiyo ngati zilowa m'maso, pakhungu, kapena m'mapumira.
- Mukamagwiritsa ntchito dibromodifluoromethane, moto kapena kutentha kwapamwamba kuyenera kupewedwa chifukwa zimatha kuyaka.
- Mukamagwiritsa ntchito dibromodifluoromethane, tsatirani machitidwe oyenera a labotale ndi njira zodzitetezera.
