Intshayelelo
I-2-nitroanisole, eyaziwa ngokuba yi-2-nitrophenoxymethane, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-nitroanisole:
Umgangatho:
I-2-Nitroanisole yikristale engenambala okanye eqinileyo etyheli enevumba elikhethekileyo lekhandlela elinomsi. Kwiqondo lokushisa kwegumbi, linokuzinza emoyeni. Iyanyibilika kwizinyibilikisi zendalo ezifana ne-ethanol, i-ether, kunye nekloroform, kodwa ayinyibiliki emanzini.
Sebenzisa:
I-2-nitroanisole isetyenziswa kakhulu njenge-reagent yekhemikhali kwi-organic synthesis reactions. Ingasetyenziswa njenge-synthetic intermediate ye-aromatics compounds ukulungiselela ezinye iikhompawundi. Inevumba elikhethekileyo lamakhandlela omsi kwaye ikwasetyenziswa njengesithako kwiziqholo.
Indlela:
Ukulungiswa kwe-2-nitroanisole ngokuqhelekileyo kufumaneka ngokuphendula kwe-anisole nge-nitric acid. Indlela ethile yokulungiselela yile ilandelayo:
1. Nyibilikisa i-anisole kwi-ether engenamanzi.
2. Kancinci ukongeza i-nitric acid dropwise kwisisombululo, gcina ukushisa kwe-reaction phakathi kwe-0-5 ° C, kwaye udibanise ngexesha elifanayo.
3. Emva kokuphendula, i-salts ye-inorganic kwisisombululo iyahlukana ngokuhluzwa.
4. Hlamba kwaye womise isigaba se-organic ngamanzi kwaye emva koko usihlambulule nge-distillation.
Ulwazi ngoKhuseleko:
I-2-Nitoanisole inefuthe elicaphukisayo emehlweni, ulusu, kunye nendlela yokuphefumla kwaye inokubangela ukurhawuzelelwa, ukudumba, kunye nokutshisa. Izixhobo ezifanelekileyo zokuzikhusela njengeendondo zokuzikhusela ngemichiza, iiglavu, nempahla yokuzikhusela zifanele zinxitywe xa zisetyenziswa okanye zilungiswa. Iqhuma kwaye kufuneka igwenywe ekudibaneni nezinto ezinokutsha, amadangatye avulekileyo kunye neendawo eziphakamileyo zokushisa. Ukuba i-compound ifakwe okanye ifakwe, kufuneka kufuneke unyango ngokukhawuleza.
