3 4-Dibromobenzoic acid (CAS# 619-03-4)
Intshayelelo
I-3,4-Dibromobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
I-3,4-Dibromobenzoic acid yikristale engenambala kunye nephunga elimnandi elikhethekileyo. Izinzile ekukhanyeni nasemoyeni, kodwa inokubola kumaqondo obushushu aphezulu.
Sebenzisa:
I-3,4-Dibromobenzoic acid ingasetyenziswa kwiimpendulo ezahlukeneyo kunye ne-reagents kwi-organic synthesis. Isenokusetyenziswa njengenye yezixhobo ze-organic light-emitting diodes (OLEDs).
Indlela:
Ukulungiswa kwe-3,4-dibromobenzoic acid inokufumaneka ngokuxutywa kwesisombululo se-bromobenzoic acid. I-asidi ye-Benzoic iqala inyibilika kwi-solvent efanelekileyo kwaye i-bromine yongezwa ngokucothayo. Emva kokuba impendulo igqityiwe, imveliso ifunyenwe ngokucoca kunye ne-crystallization.
Ulwazi ngokhuseleko: Lolodidi lwe-organic halides kwaye inomngcipheko wokuba yingozi ebantwini nakwindalo esingqongileyo. Kulumkele ukudibana ngqo nolusu kunye namehlo, kwaye qinisekisa ukuba usebenza kwindawo yelabhoratri engena umoya. Amanyathelo afanelekileyo okuzikhusela afana neeglavu, iiglasi zokhuseleko, kunye nedyasi yelebhu kufuneka ithathwe xa uphatha le khompawundi. Inkunkuma kufuneka ilahlwe ngokufanelekileyo ukuze kuthotyelwe imimiselo yendalo esingqongileyo.
