3,4-Difluorobsyl bromide ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H5BrF2. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
- 3,4-Difluorobenzyl bromide ke mokelikeli o se nang 'mala.
-E na le boima ba 1.78g/cm³ le ntlha e belang ea likhato tse 216-218 tsa Celsius.
-Ka mocheso oa kamore, e ka qhibiliha ka li-solvents tse kang ether le chloroform.
Sebelisa:
- 3,4-Difluorobenzyl bromide hangata e sebelisoa e le reagent ho organic synthesis. E ka sebelisoa ho kopanya metsoako ea manyolo ka meaho le thepa e itseng.
-E ka boela ea sebelisoa e le setsi sa meriana le chefo e bolaeang likokoanyana.
Mokhoa oa ho itokisa:
Tokisetso ea -3,4-Difluorobenzyl bromide e ka fumanoa ka ho itšoara ka 3,4-difluorobenzaldehyde le sodium bromide tlas'a maemo a loketseng a karabelo.
Lintlha tsa Tšireletseho:
- 3,4-Difluorobenzyl bromide e hloka tlhokomelo ho mehato ea tšireletso nakong ea polokelo le ho sebetsana.
-E lokela ho bolokoa ka setsing se koetsoeng, qoba ho kopana le moea le mongobo.
-Apara liatlana tse sireletsang le likhalase tse loketseng ha u sebelisa.
- Qoba ho hema, ho hlafuna kapa ho tšoara letlalo nakong ea ts'ebetso.
-Ha ho lahla litšila, ho lokela ho sebetsoa le ho lahloa ho ea ka melao e amehang ea naha le ea libaka.
Ka kopo netefatsa hore mekhoa e nepahetseng ea ts'ireletso e lateloa ka thata ha u sebelisa motsoako ona, 'me mehato e nepahetseng ea tšireletso e nkoa ho latela boemo bo itseng. Haeba u na le lipotso tse ling tsa ts'ebetso, ka kopo ikopanye le setsebi kapa tataiso e nepahetseng ea laboratori ea chemistry ea organic.
