Intshayelelo
I-2,5-Difluorobromobenzene yi-organic compound. Oku kulandelayo yintshayelelo eneenkcukacha kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
I-2,5-Difluorobromobenzene lulwelo olungenambala kunye nevumba elikhethekileyo. Ayinyibiliki kakuhle emanzini kodwa inyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers, kunye neeketones.
Sebenzisa:
I-2,5-Difluorobromobenzene idla ngokusetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis. Isenokusetyenziswa njenge-ligand ye-organometallic catalysts kwaye isetyenziswe kwiimpendulo zokutshintshwa, ukuhlangana kweempendulo, njl. kwi-organic synthesis reactions.
Indlela:
Indlela yokulungiselela i-2,5-difluorobromobenzene intsonkothile kwaye idla ngokudityaniswa zezi mpendulo zilandelayo:
Phambi kwe-bromobenzene, i-cuprous bromide kunye ne-difluoromethanesulfonamide zisabela kubukho be-bromobenzene ukuvelisa i-2,5-difluorobromobenzene.
Iphenylmagnesium bromide iphendulwa nge cuprous fluoride ukuvelisa i-2,5-diphenyldifluoroethane, ethi emva koko ixhomekeke kwibromination kunye ne-iodination reactions ukufumana i-2,5-difluorobromobenzene.
Ulwazi ngoKhuseleko:
I-2,5-Difluorobromobenzene iyacaphukisa kwaye inokubangela ukungahambi kakuhle ngokuphefumla, ukudibanisa kwesikhumba, okanye ukudibana kwamehlo. Ukuchanabeka ngokuthe ngqo eluswini nasemehlweni kufuneka kuphetshwe ngexesha lokudibana, kwaye izixhobo zokuzikhusela ezifana neeglavu zokhuselo kunye neeglavu kufuneka zinxitywe ukuba kuyimfuneko. Ekulungiseleleni nasekusebenziseni, ingqwalasela kufuneka ihlawulwe ekuthinteleni umlilo kunye nokuqhuma, kunye nokuqinisekisa iimeko ezilungileyo zokungenisa umoya. Xa usebenzisa kwaye ugcina, i-2,5-difluorobromobenzene kufuneka igcinwe kwiqondo lokushisa elifanelekileyo kunye nesitya esivaliweyo, kude nokutshisa, ukushisa kunye ne-oxidants.
