Isingeniso
Ikhwalithi:
I-2-Chloro-4-bromobenzoic acid iqinile ngokubukeka kwekristalu emhlophe. Inoncibilika kahle ekamelweni lokushisa futhi ingancibilika kwezinye izinyibilikisi ezivamile zemvelo, njenge-ethanol ne-ether.
Sebenzisa:
I-2-Chloro-4-bromobenzoic acid ingasetshenziswa njengendawo ephakathi ku-organic synthesis. Ingasetshenziswa futhi ekulungiseni ama-organic light-emitting diode (OLED) njengenye yezinto ezibalulekile kulo mkhakha.
Indlela:
I-2-Chloro-4-bromobenzoic acid ilungiswa ngezindlela ezihlukahlukene, futhi i-benzoic acid ivame ukusetshenziswa njengento yokuqala elabhorethri. Izindlela eziqondile zokuhlanganiswa zihlanganisa ukusabela okufana ne-chlorination, i-bromination, ne-carboxylation, ngokuvamile edinga ukusetshenziswa kwama-catalyst nama-reagents.
Ulwazi Lokuphepha:
I-2-Chloro-4-bromobenzoic acid iyinhlanganisela yezinto eziphilayo, futhi ngenxa yezizathu zokuphepha, izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zaselabhu kufanele zigqokwe ngesikhathi sokuphatha. Kungabangela ukucasuka kwamehlo, isikhumba, nendlela yokuphefumula futhi kudingeka kugwenywe. Kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu lapho igcinwe futhi isetshenziselwe ukugwema ukukhiqizwa kwamagesi anobuthi.
