Intshayelelo
Yikhompawundi ephilayo ene-chemical formula C7H3BrFN. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: Ikristale engenambala eqinileyo.
-Indawo yokunyibilika: malunga ne-59-61°C.
-Indawo yokubilisa: malunga ne-132-133 ℃.
-Umda wevumba: Akukho datha ethembekileyo.
-Ukunyibilika: Inyibilika kwizinyibilikisi ze-organic ezifana ne-ether, i-dimethylformamide kunye ne-benzene, ezinganyibilikiyo emanzini.
Sebenzisa:
-yi-organic synthesis intermediate engasetyenziselwa ukudibanisa iikhompawundi ezifana neziyobisi, izitshabalalisi kunye nedayi.
-Ingasetyenziswa njenge-reagent yokwazisa i-halogen kwiikhompawundi ezinevumba elimnandi kwi-organic synthesis.
Indlela yokulungiselela:
-i-fluorobenzonitrile ingalungiswa ngokudibanisa i-cuprous bromide (CuBr) kwi-4-fluorobenzonitrile (C7H4FN).
Ulwazi ngoKhuseleko:
-Inokuba iyacaphukisa kwaye idle, kwaye ukudibana nolusu kunye namehlo kunokubangela ukucaphuka.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela ezinje ngeglavu, iiglavu, kunye needyasi zelebhu ngexesha lokusebenza.
-Xa usebenzisa kunye nokugcina, kuyimfuneko ukuthobela iinkqubo zokusebenza ezikhuselekileyo kunye nokugcina ngokufanelekileyo kwisitya esitywinwe, kude ne-ignition kunye ne-oxidizing agents.
-Ukuba uphefumle okanye ungenile, funa unyango ngokukhawuleza. Ukuba uqhagamshelwano lwenzeka, ngokukhawuleza uhlambulule indawo echaphazelekayo ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
