Isingeniso
I-4-Chloro-2-bromobenzoic acid yaziwa nangokuthi i-4-chloro-2-bromobenzoic acid. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-4-Chloro-2-bromo-benzoic acid iyi-crystalline solid solid. Ine-solubility ephansi futhi ayincibiliki emanzini, kodwa iyancibilika kuzincibilikisi zemvelo.
Sebenzisa:
Le nhlanganisela ivame ukusetshenziswa njengendawo ephakathi kokusabela kwe-organic synthesis. I-4-Chloro-2-bromo-benzoic acid ingasetshenziswa futhi njengesisabalalisi sikadayi embonini yodayi.
Indlela:
Indlela evame ukusetshenziswa yokulungisa i-4-chloro-2-bromo-benzoic acid iwukusabela i-2-bromo-4-nitrobenzoic acid ne-nitrous acid ukuze kutholwe i-2-bromo-4-nitrophenol, bese umkhiqizo okuhlosiwe utholwa ngu. ukusabela kanye nokwelashwa.
Ulwazi Lokuphepha:
I-4-Chloro-2-bromo-benzoic acid ngokuvamile ibhekwa njengenobuthi obuphansi ngaphansi kwezimo ezijwayelekile zokusetshenziswa kanye nokugcinwa. Kungase kube nomthelela ocasulayo emehlweni, esikhumbeni, nasendleleni yokuphefumula. Ukuthintana ngqo nesikhumba namehlo kufanele kugwenywe ngesikhathi sokusetshenziswa, futhi izimo zokungena komoya ezinhle kufanele zigcinwe. Lapho uphathwa noma uncibilika, kufanele kuthathwe izinyathelo ezifanele zokuzivikela ezifana nokuvikela iso nesandla. Uma i-compound ihogelwa noma idliwe, funa usizo lwezokwelapha ngokushesha.
