Intangiriro
2,5-Difluorobenzyl bromide. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:
Ubwiza:
Kugaragara: 2,5-benzyl difluorobromide ni ibara ritagira ibara cyangwa umuhondo muto.
Ubucucike: 1.74-1,76 g / cm³.
Gukemura: Gushonga mumashanyarazi kama nka alcool, ethers hamwe na solide idafite polar.
Koresha:
2,5-difluorobenzyl bromide ikoreshwa cyane nkibintu bigereranijwe kandi bibisi muri synthesis.
Muri synthesis organique, ikoreshwa muburyo bwa fluor ya olefine hamwe na fluor ihitamo ya aromatic.
Uburyo:
Gutegura 2,5-difluorobenzyl bromide birashobora gukorwa nintambwe zikurikira:
Ubwa mbere, 2,5-dibromobenzyl na trifluoroacetic acide irasubizwa kandi igasubizwa muri gaze ya gaze cyangwa amazi kugirango hategurwe igisubizo cya 2,5-difluorobenzylbromide.
Ibicuruzwa byera 2,5-difluorobenzyl bromide noneho birahinduka, bigashungura, kandi byumye.
Amakuru yumutekano:
2,5-difluorobenzyl bromide ifite uburozi runaka, kandi hagomba gufatwa ingamba zumutekano mugihe uyikoresheje, wirinda guhura nuruhu, amaso ninzira zubuhumekero.
Mugihe cyo gukoresha no kwitegura, hagomba gutangwa ibikoresho bikingira bikingira nka gants ya laboratoire, amadarubindi, hamwe na masike yo gukingira.
Igomba gukorerwa ahantu hafite umwuka mwiza kandi ikirinda guhura ninkomoko yumuriro na okiside.
Iyo ubitse, 2,5-difluorobenzyl bromide igomba kubikwa ahantu hakonje, humye kandi hahumeka, kure yumuriro n’umuriro.
Nyamuneka kurikiza imyitozo ya laboratoire hamwe nubuyobozi bukoreshwa neza mugihe ukoresheje no gukoresha 2,5-difluorobenzyl bromide.
