Okwu mmalite
2,5-Difluorobenzonitrile bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ụfọdụ akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke 2,5-difluorobenzonitrile:
Ogo:
-2,5-Difluorobenzonitrile bụ kristal na-acha odo odo na-enweghị isi na-esi ísì ụtọ.
- 2,5-difluorobenzonitrile fọrọ nke nta ka ọ ghara ịsọpụ na mmiri na ụlọ okpomọkụ, ma soluble na organic solvents dị ka ethanol, acetone, wdg.
- Ọ bụ ngwakọta nwere isi ísì siri ike.
Jiri:
A na-eji 2,5-Difluorobenzonitrile eme ihe na njikọ organic dị ka reagent kemịkalụ maka nkwadebe nke ogige ndị ọzọ.
- A na-ejikarị ya eme ihe na mmeghachi omume fluorination na mmeghachi omume aromatization n'ihi na ntinye nke atom fluorine nwere ike ịgbanwe njirimara nke ogige, na-abawanye hydrophobicity ha na nkwụsi ike nke kemịkal.
Usoro:
Enwere ike ịkwadebe 2,5-difluorobenzonitrile site na mmeghachi omume ngbanwe aromatic. Usoro nkwadebe a na-emekarị bụ imeghachi para-dinitrobenzene na nitrosamines nke cuprous chloride na hydrofluoric acid na-eme ka ọ nweta 2,5-difluorobenzonitrile.
Ozi nchekwa:
- Mgbe ị na-ejizi 2,5-difluorobenzonitrile, yiri akụrụngwa nchebe kwesịrị ekwesị dị ka uwe mkpuchi kemịkalụ, enyo enyo, na uwe ụlọ nyocha.
- Ọ bụ ihe na-akpasu iwe nke nwere ike ịkpasu anya, akpụkpọ ahụ, na akụkụ iku ume.
- Ekwesịrị izere ikuku ume nke vapors ma ọ bụ uzuzu, akpụkpọ ahụ na anya anya n'oge ejizi ya.
- Ekwesịrị ịṅa ntị na usoro mgbochi ọkụ na mgbawa n'oge nchekwa na ojiji, ma zere isi ọkụ na oxidants.
