Mawu Oyamba
3,4-difluorobenzotrifluoride ndi organic pawiri ndi mankhwala chilinganizo C7H2F5. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: 3,4-difluorobenzotrifluoride ndi madzi opanda mtundu.
- Malo osungunuka: -35 ° C
- Kutentha kotentha: 114 ° C
- Kachulukidwe: 1.52g/cm³
-Kusungunuka: Kusungunuka mu zosungunulira zambiri za organic, monga ethanol, ether ndi benzene.
Gwiritsani ntchito:
-3,4-difluorobenzotrifluoride amagwiritsidwa ntchito ngati zosungunulira za organic synthesis reaction. Kusungunuka kwake kwakukulu komanso chikhalidwe cha anhydrous kumapangitsa kuti ikhale yofunikira pakuphatikizika kwachilengedwe.
-Itha kugwiritsidwanso ntchito ngati mankhwala opangira mankhwala komanso kuyeretsa.
Njira:
-3,4-difluorobenzotrifluoride angapezeke pochita 3,4-difluorophenyl hydrogen sulfide ndi barium trifluoride. Zomwe zimachitika nthawi zambiri zimakhala pamaso pa magnesium chloride, kutenthetsa kwa maola angapo, kenako ndikuchiza wapakatikati ndi mowa.
Zambiri Zachitetezo:
-3,4-difluorobenzotrifluoride ndi organic pawiri, ndipo pokoka mpweya wake ayenera kupewa.
-Valani zida zodzitetezera zoyenera monga magalasi, magolovesi ndi zovala zodzitetezera mukazigwiritsa ntchito.
-Kuwonekera kwanthawi yayitali kapena kolemera kumatha kukhala kowopsa ku thanzi ndipo kungayambitse kuyabwa kwa maso, kupuma komanso khungu.
-Pogwiritsidwa ntchito ndi posungira, samalani ndi njira zopewera moto ndi kuphulika, pewani kukhudzana ndi zotulutsa zamphamvu.
-Ngati mwangozi m'maso mwako kapena kukhudza khungu lanu, sukani nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.
