Intshayelelo
I-2,6-dinitrobenzaldehyde i-organic compound kunye ne-chemical formula C7H4N2O4. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
-Ukubonakala: 2,6-dinitrobenzaldehyde njengeekristale eziphuzi.
-Ukunyibilika: Kuphantse kwanganyibiliki emanzini, kodwa kunyibilika kwizinto ezininzi ezinyibilikisayo eziphilayo ezifana ne-ethanol, i-dichloromethane, njl.
-Indawo yokunyibilika: Indawo yayo yokunyibilika ikuluhlu lwe-145-147 degrees Celsius.
-Ivumba: Inevumba elibukhali elibukhali.
Sebenzisa:
-I-Chemical reagent: I-2,6-dinitrobenzaldehyde isoloko isetyenziswa njenge-reagent yekhemikhali ukulungiselela ezinye iikhompawundi.
I-Synthesis ephakathi: Ikwayindawo ephakathi ye-organic synthesis. Ngokomzekelo, inokusetyenziswa xa kusenziwa iidayi, izibulali-zinambuzane, amayeza nezinye izinto ezinjalo.
Indlela yokulungiselela:
-Indlela yokulungiselela i-2,6-dinitrobenzaldehyde idla ngokufezekiswa ngokuphendula kwe-nitrobenzaldehyde. Okokuqala, i-benzaldehyde kunye ne-concentrated nitric acid reaction, kwaye emva kweemeko ezifanelekileyo ze-acidic zonyango, unokufumana i-2,6-dinitrobenzaldehyde.
Ulwazi ngoKhuseleko:
- I-2,6-dinitrobenzaldehyde yinto enetyhefu kwaye kufuneka iphathwe ngononophelo. Kuphephe ukudibana ngqo nolusu, amehlo kunye nepheshana lokuphefumla.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi, kunye neengubo zelebhu xa usebenzisa okanye uphethe le khompawundi ukukhusela ukudibanisa kunye nokuphefumla.
-Inkunkuma kufuneka ilahlwe ngokweendlela ezimiselweyo ukuthintela ukungcoliseka kwendalo.
Nceda uqaphele ukuba oku kuphela isingeniso jikelele kwi-2,6-dinitrobenzaldehyde. Imisebenzi ethile yovavanyo kunye nezilumkiso zokhuseleko kufuneka zivavanywe kwaye zilandelwe ngokwemiqathango ethile. Ngalo lonke ixesha ulandela ilabhoratri kunye nemithetho yokuphatha ngokukhuselekileyo kunye nemiyalelo xa usebenzisa imichiza.
