Okwu mmalite
2-Cyano-3,5-dichloropyridine bụ ngwakọta organic na usoro kemịkalụ C6H2Cl2N2. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
2-Cyano-3,5-dichloropyridine bụ ihe siri ike na-acha odo odo na-enweghị agba. Ọ nwere obere mgbanwe na ụlọ okpomọkụ. Ọ nwere obere solubility na mmiri na nnukwu solubility na organic solvents dị ka ethanol na dimethylformamide.
Jiri:
2-Cyano-3,5-dichloropyridine nwere ọtụtụ ngwa ngwa na njikọ organic. Enwere ike iji ya mee ihe dị ka etiti maka njikọ nke ogige organic dị iche iche (dịka ọgwụ ọjọọ, akwa akwa na pesticides). Tụkwasị na nke a, a pụkwara iji ya mee ihe dị ka ihe na nyocha nke organic light-emitting diodes (OLEDs) na ihe ngosi kristal mmiri.
Ụzọ nkwadebe:
Enwere ike ịkwadebe 2-Cyano-3,5-dichloropyridine site na iji ụzọ sịntetị dị iche iche. Usoro sịntetịt a na-ahụkarị bụ iji cyanide meghachi omume na ngwakọta pyridine kwekọrọ, chlorination sochiri ya iji nweta ngwaahịa ahụ.
Ozi nchekwa:
2-Cyano-3,5-dichloropyridine nwere ike iwere ihe na-emerụ ahụ n'okpuru ọnọdụ nkịtị. Ọ nwere ike ịkpasu traktị iku ume, anya na akpụkpọ ahụ. A na-eji ya eme ihe kwesịrị ekwesị, dị ka iyi uwe aka na ugogbe anya. Zere ịkpọtụrụ ndị ọrụ oxidizing na acid siri ike n'oge nchekwa na njikwa. Ọ bụrụ na ekpughere ya ma ọ bụ ikuru ume, chọọ nlekọta ahụike ozugbo.
