2,5-Difluorobenzaldehyde. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, ụzọ mmepụta ya na ozi nchekwa:
Ogo:
2,5-Difluorobenzaldehyde bụ mmiri mmiri na-acha odo odo na-enweghị ụcha nke nwere akara ọkụ siri ike, isi na-esi ísì ụtọ na ụlọ okpomọkụ. Ọ na-esighi ike na mmiri mana enwere ike ịsacha ya na ihe mgbaze organic dị ka ethanol, toluene, wdg.
Jiri:
2,5-Difluorobenzaldehyde nwere ọtụtụ ngwa ngwa na njikọ organic. Enwere ike iji ya dị ka ihe mmalite maka njikọ nke ogige aromatic, ihe ndị na-emepụta paraphthalenedione, na ụmụ irighiri ihe ndị na-emepụta ihe. A pụkwara iji ya mee ihe na njikọ nke ogige organometallic, mkpuchi dị elu na akwa ákwà.
Usoro:
Enwere ike ịkwadebe 2,5-difluorobenzaldehyde site na mmeghachi omume nke benzaldehyde na hydrogen fluoride. A na-eme mmeghachi omume a n'okpuru ọnọdụ acidic ma nwee ike nweta ya site na iji hydrofluoric acid dị ka isi iyi nke hydrogen fluoride.
Ozi nchekwa:
Ekwesịrị ịkpachara anya mgbe ị na-eji 2,5-difluorobenzaldehyde. Ọ nwere mgbakasị ahụ na akpụkpọ ahụ, anya na akụkụ iku ume.
