3-Bromo -5-iodobenzoic acid (CAS# 188815-32-9) Isingeniso
-Ukubukeka: I-3-Bromo-5-iodobenzoic acid iyi-crystalline emhlophe noma ephuzi ephuzi eqinile.
-I-Solubility: Ingancibilika ngokwengxenye kuzincibilikisi, njenge-alcohols nama-ketones, kodwa ukuncibilika kwayo emanzini kuphansi.
-Indawo yokuncibilika: Inephuzu lokuncibilika eliphakeme, ngokuvamile phakathi kuka-120-125°C.
-Izakhiwo zamakhemikhali: I-3-Bromo-5-iodobenzoic acid iyi-asidi ebuthakathaka engakwazi ukukhiqiza usawoti ohambisanayo ngaphansi kwezimo ze-alkaline.
Sebenzisa:
I-3-Bromo-5-iodobenzoic acid isetshenziswa kakhulu ku-organic synthesis, ikakhulukazi njengendawo emaphakathi ekuhlanganiseni kwezidakamizwa. Ingasetshenziselwa ukuhlanganisa imithi elwa nomalaleveva njenge-chloroquine. Ngaphezu kwalokho, ingasetshenziswa ekuhlanganiseni ezinye izinto eziphilayo ezinjengamadayi nezibulala-zinambuzane.
Indlela:
I-3-Bromo-5-iodobenzoic acid ingalungiswa nge-chloroalkylation. Okokuqala, inhlanganisela ye-chloro ikhiqizwa ukusabela kwe-O-iodobenzoic acid ne-bromide yethusi, bese iguqulwa ibe yi-3-Bromo-5-iodobenzoic acid nge-bromination.
Ulwazi Lokuphepha:
I-3-Bromo-5-iodobenzoic acid ngokuvamile iphephe kakhulu ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Nokho, njengekhemikhali, kuseyingozi. Ukuthinta isikhumba namehlo kungase kubangele ukucasuka nokusha. Ngakho-ke, gqoka izinto zokuzivikela ezifanele njengamagilavu nezibuko ngesikhathi sokusebenzisa. Ngesikhathi esifanayo, gwema ukuhogela uthuli noma isisombululo sayo. Enqubweni yokugcina nokuphatha, idinga ukuphathwa kahle ukuze igweme isitoreji ngezinto ezivuthayo, ama-oxidants nezinye izinto. Uma kuvuza ngengozi, kuzothathwa izinyathelo ezifanele ukukhuculula nokubhekana nakho. Ekuphatheni amakhemikhali anjalo, kufanele alandele izinqubo zokuphepha ezifanele kanye neziqondiso.
