3-Bromo -5-iodobenzoic acid (CAS# 188815-32-9) Intshayelelo
-Inkangeleko: I-3-Bromo-5-iodobenzoic acid yikristale emhlophe okanye ephaphathekileyo.
-I-Solubility: Inonyibilika ngokuyinxenye kwii-solvents, ezifana ne-alcohols kunye ne-ketones, kodwa ukunyibilika kwayo emanzini kuphantsi.
-Indawo yokunyibilika: Inendawo ephezulu yokunyibilika, ngokuqhelekileyo iphakathi kwe-120-125°C.
-Iipropati zeKhemikhali: I-3-Bromo-5-iodobenzoic acid yi-asidi ebuthakathaka enokuvelisa iityuwa ezihambelanayo phantsi kweemeko ze-alkali.
Sebenzisa:
I-3-Bromo-5-iodobenzoic acid isetyenziswa ikakhulu kwi-organic synthesis, ngakumbi njengendawo ephakathi kwi-synthesis yeziyobisi. Ingasetyenziselwa ukwenza amachiza okulwa nesifo seengcongconi njenge chloroquine. Ukongeza, ingasetyenziselwa ukuhlanganiswa kwezinye izinto eziphilayo ezifana nedayi kunye ne-pesticides.
Indlela:
I-3-Bromo-5-iodobenzoic acid ingalungiswa nge-chloroalkylation. Okokuqala, i-chloro compound yenziwa ngokuphendula kwe-O-iodobenzoic acid kunye ne-bromide yobhedu, kwaye emva koko iguqulelwe kwi-3-Bromo-5-iodobenzoic acid nge-bromination.
Ulwazi ngoKhuseleko:
I-3-Bromo-5-iodobenzoic acid ikhuselekile ngokubanzi phantsi kweemeko eziqhelekileyo zokusetyenziswa. Nangona kunjalo, njengekhemikhali, iseyingozi. Ukudibana nolusu kunye namehlo kunokubangela ukucaphuka kunye nokutshisa. Ke ngoko, nxiba izixhobo ezifanelekileyo zokukhusela ezinje ngeeglavu kunye neeglavu ngexesha lokusetyenziswa. Kwangaxeshanye, kuphephe ukuphefumlela uthuli okanye isisombululo sayo. Kwinkqubo yokugcina kunye nokuphatha, kufuneka ilawulwe ngokufanelekileyo ukuphepha ukugcinwa kwezinto ezinokutsha, i-oxidants kunye nezinye izinto. Kwimeko yokuvuza ngengozi, amanyathelo afanelekileyo aya kuthatyathwa ukuyicoca kunye nokujongana nayo. Ekuphatheni iikhemikhali ezinjalo, kufuneka zilandele iinkqubo ezifanelekileyo zokhuseleko kunye nezikhokelo.
