Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C7H3BrF4. Ndi madzi achikasu otumbululuka opanda mtundu ndi fungo lapadera kutentha.
Chilengedwe:
1. Posungunuka: -33 ℃
2. Malo otentha: 147-149 ℃
3. kachulukidwe: 1.889g/cm³
4. Kusungunuka: Kusungunuka mu zosungunulira za organic monga etha, ethanol ndi dichloromethane, zosasungunuka m'madzi.
Gwiritsani ntchito:
Amagwiritsidwa ntchito makamaka ngati wapakatikati mu kaphatikizidwe ka organic. Amagwiritsidwa ntchito popanga mankhwala, catalysis mankhwala ndi zinthu organic, monga benzopyrazolones, cyclic macrocyclization, organic photoelectric materials synthesis, etc.
Njira Yokonzekera:
Kukonzekera njira kashiamu ndi makamaka mwa zimene bromobenzene ndi trifluorotoluene pa zinthu zoyenera. Nthawi zambiri, bromobenzene imakumana ndi trifluorotoluene pamaso pa ufa wamkuwa kapena cuprous pansi pa kutentha kupanga fluorotoluene.
Zambiri Zachitetezo:
Zimakwiyitsa ndipo sayenera kukhudzana mwachindunji ndi khungu ndi maso. Zida zodzitetezera monga magolovesi odzitetezera, magalasi ndi zovala zodzitetezera ziyenera kuvalidwa panthawi yogwiritsira ntchito ndikugwira. Pewani kulowetsa nthunzi yake ndikuonetsetsa kuti ikugwirira ntchito pamalo abwino mpweya wabwino. Komanso, ziyenera kusungidwa mu chidebe chosindikizidwa, kutali ndi kutentha ndi magwero a moto. Mukamagwiritsa ntchito kapena kutaya, chonde tsatirani njira zoyenera zotetezera. Ngati kutayikira kukuchitika, njira zoyenera zoyeretsera ndi kutaya ziyenera kuchitidwa. Ngati ndi kotheka, katswiri ayenera kufunsa.
