Intshayelelo
I-5,6-Dichloronicotinic acid yi-organic compound. Oku kulandelayo yinkcazo eneenkcukacha yobume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-5,6-Dichloronicotinic acid ayinambala kwiikristale ezimthubi ezikhanyayo okanye i-crystalline powder.
- Ukunyibilika: ukunyibilika kwiialkoholi kunye nee-ethers, ukunyibilika kancinane emanzini.
Sebenzisa:
- I-5,6-i-Dichloronicotinic acid idla ngokusetyenziswa njenge-reagent yekhemikhali njenge-oxidant, i-agent yokunciphisa kunye ne-catalyst kwi-organic synthesis reactions.
Indlela:
- I-5,6-dichloronicotinic acid idla ngokulungiswa nge-nitroreduction ye-p-nitrophenol. I-Nitrophenol iphathwa nge-nitrous acid ukuvelisa i-5,6-dinitrophenol. Emva koko, i-5,6-dinitrophenol iyancipha ibe yi-5,6-dichloronicotinic acid isebenzisa i-chlorine okanye i-nitroreducing agents.
Ulwazi ngoKhuseleko:
- Uthuli okanye i-crystals ye-5,6-dichloronicotinic acid inefuthe elicasulayo kwaye inokubangela ukucaphuka kwamehlo, ulusu kunye nokuphefumula.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana nempahla yamehlo ekhuselayo, iiglavu kunye neziphefumla xa usetyenziswa.
- Kuphephe ukuphefumla uthuli kwaye uphephe ukudibana kwesikhumba.
- Ngexesha lokugcinwa kunye nokuphatha, thintela ukudibanisa kunye ne-oxidizing agents ezinamandla okanye izinto ezinokutsha.
- Kwimeko yokuvezwa ngengozi kwi-5,6-dichloronicotin, hlambulula indawo echaphazelekayo ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango.
