Intshayelelo
I-2-Chloro-5-bromo-3-nitropyridine i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
I-2-Chloro-5-bromo-3-nitropyridine iqinile emhlophe kunye nevumba elibi. Inonyibiliko oluphakathi kwaye iyanyibilika kwizinyibilikisi zendalo ezifana neealkoholi kunye neekhabhoni ezikloriniweyo.
Usetyenziso: Ingasetyenziselwa uphando kunye nezicelo zaselabhoratri.
Indlela:
Indlela yokulungiselela i-2-chloro-5-bromo-3-nitropyridine inokufumaneka ngeendlela ezahlukeneyo. Indlela eqhelekileyo kukufezekisa ukutshintshwa kweklorini kunye ne-bromine ngokongeza i-aluminium chloride okanye ezinye i-sulfate phantsi kweemeko ze-alkali ze-3-bromo-5-nitropyridine. Iindlela zokudibanisa ezineenkcukacha zingathunyelwa kuncwadi lwekhemikhali okanye kwiincwadana zobungcali.
Ulwazi ngoKhuseleko:
Le khompawundi yi-agent eyomeleleyo ye-oxidizing kwi-organic synthesis kwaye ifuna inkathalo xa igcinwa kwaye iphathwa kwimeko yomlilo okanye ukuqhuma.
Gwema ukudibanisa nezinto ezinokutsha, ii-agent zokunciphisa kunye nezinto ezinokutsha.
Izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu zelebhu, iiglasi, kunye neegawuni kufuneka zinxitywe ngexesha lokuphatha nokuphatha.
Kuphephe ukuphefumla, ukungeniswa, okanye ukudibana kwesikhumba.
Kufuneka igcinwe yomile xa igcinwe kwaye igweme ukudibanisa nomswakama emoyeni.
Xa ichithwa, kufuneka ilahlwe ngokuhambelana nemimiselo yendawo kwaye akufanele ilahlwe okanye ikhutshwe kwindalo.
