Isingeniso

I-2-Cyano-3,5-dichloropyridine iyinhlanganisela ye-organic ene-chemical formula C6H2Cl2N2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

 

Imvelo:

I-2-Cyano-3,5-dichloropyridine iqinile eliphuzi elingenambala noma eliphaphathekile. Inokuguquguquka okuphansi ekamelweni lokushisa. Ine-solubility ephansi emanzini kanye ne-solubility ephezulu kuma-organic solvents njenge-ethanol ne-dimethylformamide.

 

Sebenzisa:

I-2-Cyano-3,5-dichloropyridine inohlu olubanzi lwezinhlelo zokusebenza ku-organic synthesis. Ingasetshenziswa njengendawo ephakathi yokuhlanganiswa kwezinto ezihlukahlukene eziphilayo (njengezidakamizwa, odayi kanye nezibulala-zinambuzane). Ngaphezu kwalokho, ingasetshenziswa futhi njengento ebalulekile ocwaningweni lwama-organic light-emitting diode (OLED) nezibonisi zekristalu eliwuketshezi.

 

Indlela Yokulungiselela:

I-2-Cyano-3,5-dichloropyridine ingalungiswa ngokusebenzisa izindlela ezahlukene zokwenziwa. Indlela yokwenziwa evamile iwukusabela inhlanganisela ye-pyridine ehambisanayo ne-cyanide, elandelwa yi-chlorination ukuthola umkhiqizo.

 

Ulwazi Lokuphepha:

I-2-Cyano-3,5-dichloropyridine ingabhekwa njengeyingozi ngaphansi kwezimo ezivamile. Kungase kucasule umgudu wokuphefumula, amehlo nesikhumba. Lapho isetshenziswa, kufanele ithathe izinyathelo ezifanele zokuzivikela, njengokugqoka amagilavu ​​nezibuko. Gwema ukuthintana nama-oxidizing agents kanye nama-acids aqinile ngesikhathi sokugcina nokuphatha. Uma uveziwe noma uhogelwe, funa usizo lwezokwelapha ngokushesha.
