Mawu Oyamba
2-(trifluoromethoxy)fluorobenzene(2-(trifluoromethoxy)fluorobenzene) ndi organic pawiri ndi mankhwala chilinganizo C7H4F4O. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: 2-(trifluoromethoxy)fluorobenzene ndi madzi opanda mtundu.
-Kusungunuka: Kutha kusungunuka mu zosungunulira za organic, monga etha, ma hydrocarboni a chlorinated.
- Malo osungunuka ndi malo owira: Malo osungunuka ndi -30 ° C, ndipo malo owira ndi 50-51 ° C.
-Kachulukidwe: Kachulukidwe wapawiri ndi pafupifupi 1.48g/cm³.
-Hazard: 2-(trifluoromethoxy)fluorobenzene ndi madzi oyaka omwe amatha kuyatsa moto akayatsidwa ndi malawi otseguka kapena kutentha kwambiri.
Gwiritsani ntchito:
-Pharmaceutical Chemistry: 2-(trifluoromethoxy) fluorobenzene angagwiritsidwe ntchito ngati yofunika wapakatikati yokonza mankhwala, mankhwala ndi mankhwala ena organic.
-Kaphatikizidwe wa mankhwala heterocyclic: Angagwiritsidwe ntchito synthesize zosiyanasiyana heterocyclic mankhwala, monga hydrogen munali heterocycles, nayitrogeni munali heterocycles, etc.
Njira:
2-(trifluoromethoxy)fluorobenzene nthawi zambiri amakonzedwa ndi reacting aryne ndi fluorinating agent, ndipo masitepe ake ndi awa:
1. The arylalkyne imachitidwa ndi fluorinating agent. Zomwe zimagwiritsidwa ntchito pa fluorinating ndi ammonium hydrogen borate (NH4HF2) ndi fluoride yachitsulo.
2. Wapakatikati wopangidwa ndi zomwe amachitira amakumana ndi methanol kuti apeze 2-(trifluoromethoxy)fluorobenzene.
Zambiri Zachitetezo:
-Mukamagwiritsira ntchito ndi kusunga 2-(trifluoromethoxy)fluorobenzene, tsatirani mosamalitsa njira zachitetezo ndikupewa kukhudzana ndi khungu, maso ndi kupuma kwa nthunzi yake.
-Chigawochi chimatha kuyaka ndipo chimayenera kutetezedwa ndi moto komanso malo otentha.
-Valani magolovesi oteteza, magalasi ndi zovala zodzitchinjiriza kuti mukhale ndi mpweya wabwino mukamagwira ntchito.
Chonde dziwani kuti 2-(trifluoromethoxy)fluorobenzene ndi mankhwala, ndipo njira zotetezera ziyenera kutsatiridwa panthawi ya opaleshoni kupewa ngozi ndi kuvulala.
