Intshayelelo
I-4-Chloro-2-bromobenzoic acid ikwabizwa ngokuba yi-4-chloro-2-bromobenzoic acid. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
I-4-Chloro-2-bromo-benzoic acid iyikristale emhlophe eqinileyo. Inonyibiliko oluphantsi kwaye phantse ayinyibiliki emanzini, kodwa iyanyibilika kwizinyibilikisi zendalo.
Sebenzisa:
Le khompawundi isoloko isetyenziswa njengendawo ephakathi kwi-organic synthesis reactions. I-4-Chloro-2-bromo-benzoic acid ingasetyenziselwa njenge-disperant yedayi kwishishini ledayi.
Indlela:
Indlela esetyenziswa ngokuqhelekileyo ukulungiselela i-4-chloro-2-bromo-benzoic acid kukusabela i-2-bromo-4-nitrobenzoic acid kunye ne-nitrous acid ukufumana i-2-bromo-4-nitrophenol, kwaye ke imveliso ekujoliswe kuyo ifunyenwe. impendulo kunye nonyango.
Ulwazi ngoKhuseleko:
I-4-Chloro-2-bromo-benzoic acid ngokuqhelekileyo ithathwa njengetyhefu ephantsi phantsi kokusetyenziswa okuqhelekileyo kunye neemeko zokugcina. Isenokuba nefuthe elicaphukisayo emehlweni, eluswini nakwindlela yokuphefumla. Ukudibana ngokuthe ngqo kwesikhumba kunye namehlo kufuneka kugwenywe ngexesha lokusetyenziswa, kwaye iimeko ezifanelekileyo zokungenisa umoya kufuneka zigcinwe. Xa uphathwa okanye unyibilika, kufuneka kuthathwe amanyathelo afanelekileyo okuzikhusela anjengokhuseleko lwamehlo nesandla. Ukuba i-compound ifakwe okanye ifakwe, funa unyango ngokukhawuleza.
