Intshayelelo
I-2-Fluoro-4-bromobenzyl bromide yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 2-Fluoro-4-bromobenzyl bromide lulwelo olungenambala ukuya kumthubi.
- Ukunyibilika: Inyibilika kwizinyibilikisi zendalo ezifana neealkoholi kunye ne-ethers, kodwa ayinyibiliki emanzini.
Sebenzisa:
- I-2-Fluoro-4-bromobenzyl bromide isoloko isetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis.
- Le khompawundi inokusetyenziswa njengemathiriyeli ekrwada yee-catalysts kunye ne-surfactants.
Indlela:
Indlela yokulungiselela i-2-fluoro-4-bromobenzyl bromide yile ilandelayo:
- Ukusabela kwe-2-bromobenzyl yotywala kunye ne-2,4-difluorobenzoic acid, i-catalyzed by alkali, kwiqondo lokushisa elifanelekileyo kunye neemeko zexesha.
- Emva kokuba impendulo igqityiwe, ukuhlanjululwa kunye nokwahlula kuqhutyelwa nge-crystallization okanye i-distillation ukufumana i-bromide ye-2-fluoro-4-bromobenzyl ngokucoceka okuphezulu.
Ulwazi ngoKhuseleko:
- I-2-Fluoro-4-bromobenzyl i-bromide yinto eguqukayo ye-organic compound kwaye umphunga wayo kufuneka ugwenywe ngokuphefumla.
- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglasi zokhuselo, iiglavu kunye needyasi zelebhu ngexesha lokuphatha nokuphatha.
- Xa ugcina kwaye usebenzisa, thintela ukudibana nee-oxidants, ii-asidi ezinamandla, ii-alkali ezinamandla kunye nezinye izinto ukuphepha ukuphendula okuyingozi.
- Xa ugcina kwaye ulahla, imithetho efanelekileyo, imimiselo kunye nemimiselo yokhuseleko kufuneka ilandelwe.
