Okwu mmalite
2,5-Difluorobenzyl bromide. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, usoro nkwadebe na ozi nchekwa ya:
Ogo:
Ọdịdị: 2,5-benzyl difluorobromide bụ mmiri na-enweghị agba ma ọ bụ ntakịrị odo odo.
Njupụta: 1.74-1.76 g/cm³.
Solubility: Soluble na organic solvents dị ka alcohols, ethers na ndị na-abụghị polar solvents.
Jiri:
A na-ejikarị 2,5-difluorobenzyl bromide mee ihe dị ka etiti na akụrụngwa akụrụngwa na njikọ organic.
Na njikọ nke organic, a na-ejikarị ya eme ihe maka fluorine nke olefins na ịhọrọ fluorination nke ogige aromatic.
Usoro:
Enwere ike ịme nkwadebe nke 2,5-difluorobenzyl bromide site na usoro ndị a:
Nke mbụ, 2,5-dibromobenzyl na trifluoroacetic acid na-emeghachi omume na reflux na condensate gas ma ọ bụ mmiri iji kwadebe ngwọta 2,5-difluorobenzylbromide.
A na-emezi ngwaahịa 2,5-difluorobenzyl bromide dị ọcha, kpochaa ma kpọọ nkụ.
Ozi nchekwa:
2,5-difluorobenzyl bromide nwere ụfọdụ toxicity, na nchekwa nchekwa kwesịrị ịkpachara anya mgbe ị na-eji ya, na-ezere kọntaktị na akpụkpọ ahụ, anya na akụkụ iku ume.
Mgbe a na-eji ya na nkwadebe, ekwesịrị ịnye ngwa nchebe kwesịrị ekwesị dị ka uwe ụlọ nyocha, enyo enyo, na ihe mkpuchi nchebe.
Ekwesịrị iji ya rụọ ọrụ na mpaghara ikuku nke ọma ma zere kọntaktị na isi mmalite ọkụ na oxidants.
Mgbe ị na-echekwa, a ga-edobe 2,5-difluorobenzyl bromide n'ebe dị jụụ, nke akọrọ na ikuku, na-esi na ọkụ na combustible.
Biko soro omume ụlọ nyocha kwesịrị ekwesị yana ntuziaka njikwa nchekwa mgbe ị na-eji yana 2,5-difluorobenzyl bromide.
