Intshayelelo
i-organic compound, i-chemical formula ye-C7H3BrF4, inkangeleko yayo ayinambala okanye i-light yellow liquid. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Ubuninzi: malunga. 1.894g/cm³
-Indawo yokunyibilika: malunga ne -23°C
-Indawo yokubila: malunga ne-166-168 °C
-I-Solubility: I-soluble kwii-solvents eziqhelekileyo ze-organic, ezifana ne-ethanol, i-dimethylformamide kunye ne-dichloromethane.
Sebenzisa:
Isetyenziswa ikakhulu kwintsimi ye-organic synthesis njengento ekrwada yokwenziwa kweentlobo ngeentlobo zamachiza kunye neziphakathi. Isetyenziswa ngokuqhelekileyo kwi-fluorination reactions kunye ne-alkylation reactions. Ukongeza, ingasetyenziselwa ukulungisa izitshabalalisi, izinto zombane kunye nezinye izinto eziphilayo.
Indlela yokulungiselela:
Kukho iindlela ezininzi ze-synthesis ye-phosphor, kwaye indlela eqhelekileyo ifunyenwe ngokuphendula kwe-4-bromo-fluorobenzene kunye negesi ye-fluorine phambi kwe-catalyst. Indlela ethile yokulungiselela idinga imisebenzi kunye neemeko ezithile zelabhoratri.
Ulwazi ngoKhuseleko:
-ikhuselekile ngokubanzi phantsi kweemeko zokusetyenziswa eziqhelekileyo. Nangona kunjalo, nayiphi na into yeekhemikhali kufuneka isetyenziswe ngokuchanekileyo kwaye ilandele iinkqubo zokusebenza ezikhuselekileyo.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu zokukhusela, iiglasi kunye neemaski zokukhusela xa usetyenziswa.
-Kuphephe ukuphefumla umphunga wayo okanye ukudibana nolusu namehlo.
-Ngexesha lokugcinwa kunye nokuphatha, thintela ukudibanisa ne-oxidants eqinile kunye neemeko eziphezulu zokushisa.
-Kwimeko yokunxibelelana ngengozi okanye ukusetyenziswa kakubi, funa unyango ngokukhawuleza.
