Nhanganyaya
2-Cyano-3,5-dichloropyridine is organic compound ine kemikari formula C6H2Cl2N2. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
2-Cyano-3,5-dichloropyridine haina ruvara kana yakachenuruka yero yakasimba. Iine low volatility pakupisa kwekamuri. Iyo ine yakaderera solubility mumvura uye yakanyanya kunyungudika mune organic solvents senge ethanol uye dimethylformamide.
Shandisa:
2-Cyano-3,5-dichloropyridine ine huwandu hwakawanda hwemashandisirwo muorganic synthesis. Inogona kushandiswa sechinhu chepakati chekugadzirwa kweakasiyana organic komisheni (semishonga, dhayi uye mishonga yezvipembenene). Pamusoro pezvo, inogona zvakare kushandiswa sechinhu mukutsvagisa kweorganic light-emitting diodes (OLEDs) uye liquid crystal displays.
Kugadzirira nzira:
2-Cyano-3,5-dichloropyridine inogona kugadzirirwa uchishandisa nzira dzakasiyana dzekugadzira. Imwe nzira yekugadzira yakajairika ndeyekuita iyo inoenderana pyridine komputa ine cyanide, inoteverwa neklorini kuti uwane chigadzirwa.
Zvekuchengetedza
2-Cyano-3,5-dichloropyridine inogona kuonekwa inokuvadza pasi pemamiriro ezvinhu. Inogona kunge inogumbura kumhepo yekufema, maziso uye ganda. Mukushandiswa, inofanira kutora matanho ekudzivirira akakodzera, sekupfeka magirovhosi nemagirazi. Dzivisa kusangana neoxidizing agents uye yakasimba acids panguva yekuchengetedza nekubata. Kana akafumurwa kana kufemerwa, tsvaga kurapwa nekukurumidza.
