Intshayelelo
I-2,5-Dichloro-3-nitropyridine i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 2,5-Dichloro-3-nitropyridine yikristale engenambala ukuya kumthubi.
- Ukunyibilika: Inyibilika kwizinyibilikisi ze-organic ezifana ne-ethanol, i-dimethyl ether kunye ne-chloroform, kodwa i-soluble encinci emanzini.
- Uzinzo: Ikhompawundi izinzile kwiqondo lokushisa, kodwa iqhuma kwiqondo lokushisa eliphezulu okanye idibene ne-oxidizing agents ezinamandla.
Sebenzisa:
- Amayeza okubulala izitshabalalisi: Ingasetyenziswa njengesitshabalalisi kwaye inefuthe elihle lokulawula ezinye izitshabalalisi.
Indlela:
Indlela yokudibanisa ye-2,5-dichloro-3-nitropyridine idla ngokubandakanya i-nitrification reaction kunye ne-chlorination reaction. Phakathi kwabo, indlela ye-synthesis yendabuko yi-nitrate 2,5-dichloropyridine kunye ne-nitric acid phambi kwe-sulfuric acid. Enye indlela yokusabela i-2-nitro-5-chloropyridine nge-acidic copper bromide ukuvelisa i-2,5-dichloro-3-nitropyridine.
Ulwazi ngoKhuseleko:
- I-2,5-Dichloro-3-nitropyridine i-organic compound kufuneka iphathwe ngononophelo ukukhusela ukuba ingadibanisi nesikhumba, amehlo kunye nenkqubo yokuphefumula.
-Nxiba izixhobo ezifanelekileyo zokukhusela, kubandakanywa iimpahla zamehlo ezikhuselayo, iiglavu kunye nezikhuselo zobuso, xa usebenza.
- Ngexesha lokusebenza, kuphephe ukuphefumla iigesi, inkungu okanye umphunga kwaye ugcine umoya olungileyo.
- Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye udibane nodokotela.
- Xa ugcina, i-2,5-dichloro-3-nitropyridine kufuneka igcinwe kwindawo eyomileyo, epholileyo, epholileyo, ngaphandle kokutshisa kunye ne-oxidants.
