Isingeniso
Izakhiwo: I-5-bromo-2-pyridine carboxylic acid iyimpushana ecwebezelayo engenambala ukuya kokuphuzi. Iyancibilika emanzini, utshwala ne-ether, futhi inyibilika kancane ku-benzene ne-petroleum ether. Iyazinzile ekamelweni lokushisa, kodwa ibola kalula emazingeni okushisa aphezulu.
Ukusetshenziswa: I-5-bromo-2-pyridine carboxylic acid ivamise ukusetshenziswa njengendawo ephakathi ku-organic synthesis.
Indlela yokulungiselela: Kunezindlela eziningana zokulungiselela i-5-bromo-2-pyridine carboxylic acid. Indlela evamile iwukusabela i-2-pyridine carboxylic acid ne-bromine ukukhiqiza i-5-bromo-2-pyridine carboxylic acid. Lokhu kusabela kungenziwa nge-acetic acid futhi izinga lokushisa lokusabela lishiswa ekamelweni lokushisa. Ekupheleni kokusabela, umkhiqizo ungatholakala nge-crystallization nokuhlunga.
Ulwazi Lokuphepha: I-5-Bromo-2-pyridine carboxylic acid ngokuvamile iphephile ngaphansi kwezimo ezivamile zokusetshenziswa. Izinqubo zokusebenza eziphephile kufanele zilandelwe futhi zigcinwe endaweni eyomile, epholile, kude nokushisa kanye nama-oxidants.
