Isingeniso
I-2-Fluoro-4-bromobenzyl bromide iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2-Fluoro-4-bromobenzyl bromide iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile.
- Ukunyibilika: Incibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether, kodwa ayincibiliki emanzini.
Sebenzisa:
- I-2-Fluoro-4-bromobenzyl bromide ivamise ukusetshenziswa njengento ebalulekile emaphakathi ekuhlanganiseni kwe-organic.
- Le nhlanganisela ingasetshenziswa futhi njengento eluhlaza yama-catalysts nama-surfactants.
Indlela:
Indlela yokulungiselela i-2-fluoro-4-bromobenzyl bromide imi kanje:
- Ukusabela kwe-2-bromobenzyl alcohol ne-2,4-difluorobenzoic acid, eyenziwe yi-alkali, ezingeni lokushisa elifanele kanye nezimo zesikhathi.
- Ngemuva kokuthi ukusabela kuqediwe, ukuhlanzwa nokuhlukaniswa kwenziwa nge-crystallization noma i-distillation ukuthola i-bromide engu-2-fluoro-4-bromobenzyl ngokuhlanzeka okuphezulu.
Ulwazi Lokuphepha:
- I-2-Fluoro-4-bromobenzyl bromide iyinhlanganisela yezinto eziphilayo ezishintshashintshayo futhi umhwamuko wayo kufanele ugwenywe ngokuhogela.
- Gqoka izinto zokuzivikela ezifanele njengezingilazi zokuzivikela, amagilavu namajazi elebhu ngesikhathi sokuphatha nokuphatha.
- Lapho ugcina futhi usebenzisa, gwema ukuthintana nama-oxidants, ama-asidi aqinile, ama-alkali aqinile nezinye izinto ukuze ugweme ukusabela okuyingozi.
- Lapho uyigcina futhi uyilahla, imithetho efanele, iziqondiso kanye nemithethonqubo yokuphepha kufanele ilandelwe.
