1-Bromo-2-fluoro-5-(trifluoromethoxy)benzene (CAS# 286932-57-8)

Isingeniso

I-2-bromo-1-fluoro-4-(trifluoromethoxy)benzene ingxube yemvelo enefomula yamakhemikhali ethi C7H3BrF4O.

Imvelo:

I-2-bromo-1-fluoro-4-(trifluoromethoxy)benzene iwuketshezi olungenambala ukuya kokuphuzi kancane olunephunga elimnandi. Inokuminyana okungu-1.834g/cm³, indawo yokubilisa engu-156-157 ° C, kanye nephuzu elikhanyayo elingu-62 ° C. Incibilika kuzincibilikisi ezivamile ezifana ne-ethanol, i-dimethylformamide ne-dichloromethane.

Sebenzisa:

I-2-bromo-1-fluoro-4-(trifluoromethoxy)benzene isetshenziswa kakhulu njenge-reagent ekuphenduleni kwe-organic synthesis. Ingathula ama-athomu e-fluorine ne-bromine ekuhlanganiseni kwezinhlanganisela ezinuka kamnandi, futhi isetshenziselwa ukulungiswa kwezidakamizwa eziphilayo kanye nezibulala-zinambuzane.

Indlela:

Ukulungiswa kwe-2-bromo-1-fluoro-4-(trifluoromethoxy)benzene ngokuvamile kwenziwa ngezindlela zokuhlanganisa amakhemikhali. Enye indlela evamile yokulungiselela ukusabela kwe-2-fluoro-5-(trifluoromethoxybenzene) ne-bromine ngaphansi kwezimo ezine-acidic.

Ulwazi Lokuphepha:

I-2-bromo-1-fluoro-4-(trifluoromethoxy)benzene ingaba yingozi futhi icasule abantu. Ngesikhathi sokusetshenziswa nokugcinwa, kuyadingeka ukuthatha izinyathelo ezidingekayo zokuphatha nokuphepha, njengokugqoka izinto zokuzivikela ezifanele (njengamagilavu ​​nezibuko), ukugwema ukuthintana nesikhumba namehlo, nokugcina izimo ezinhle zokungenisa umoya. Lapho uphatha le nhlanganisela, landela izinqubo zokuphepha ezifanele futhi ulandele ngokuqinile izincomo eziseshidini ledatha yokuphepha.
