Intangiriro
2,5-Difluorobromobenzene nikintu kama. Ibikurikira nintangiriro irambuye kumiterere yayo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
2,5-Difluorobromobenzene ni amazi atagira ibara afite impumuro idasanzwe. Ntishobora gushonga cyane mumazi ariko irashobora gushonga mumashanyarazi nka alcool, ethers, na ketone.
Koresha:
2,5-Difluorobromobenzene ikoreshwa nkigihe kinini cyingenzi muri synthesis. Irashobora kandi gukoreshwa nka ligand ya catalizator ya organometallic kandi igakoreshwa muburyo bwo gusimbuza, guhuza reaction, nibindi mubitekerezo bya synthesis.
Uburyo:
Uburyo bwo gutegura 2,5-difluorobromobenzene buragoye kandi mubisanzwe birashobora guhuzwa nuburyo bukurikira:
Imbere ya bromobenzene, cuprous bromide na difluoromethanesulfonamide iraboneka imbere ya bromobenzene kugirango itange 2,5-difluorobromobenzene.
Phenylmagnesium bromide ikorwa na fluoride ya cuprous kugirango itange 2,5-diphenyldifluoroethane, hanyuma ikorerwa bromination na iyode kugirango ibone 2,5-difluorobromobenzene.
Amakuru yumutekano:
2,5-Difluorobromobenzene irakaze kandi irashobora gutera ikibazo cyo guhumeka, guhuza uruhu, cyangwa guhuza amaso. Guhura neza nuruhu n'amaso bigomba kwirindwa mugihe cyo guhura, kandi ibikoresho byo kurinda umuntu nka gants zo kurinda hamwe na gogles bigomba kwambara nibiba ngombwa. Mugutegura no kuyikoresha, hagomba kwitonderwa gukumira umuriro no guturika, kandi hagashyirwaho uburyo bwiza bwo guhumeka. Iyo ukoresheje no kubika, 2,5-difluorobromobenzene igomba kubikwa ku bushyuhe bukwiye no mu kintu gifunze, kure y’umuriro, ubushyuhe na okiside.
