Intshayelelo
I-3-Cyano-4-fluorobenzaldehyde (eyaziwa ngokuba yi-4-fluorobenzoyl cyanide) yinto ephilayo. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-3-Cyano-4-fluorobenzaldehyde yinto eqinileyo yekristale engenambala.
- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether kunye ne-chloroform, kodwa ayinyibiliki emanzini.
Sebenzisa:
Indlela:
- I-3-Cyano-4-fluorobenzaldehyde inokufumaneka nge-esterification ye-3-cyano-4-fluorobenzonitrile nge-asidi. Ngeendlela ezithile zokulungiselela, nceda ujonge iindlela ezithile zovavanyo kuncwadi lwe-organic synthesis kunye neencwadana zobugcisa.
Ulwazi ngoKhuseleko:
- Ulwazi oluncinci luyafumaneka kwityhefu kunye neengozi ze-3-cyano-4-fluorobenzaldehyde. Njengomxube wezinto eziphilayo, kubalulekile ukuba uqaphele ukuba ukuphathwa kwebhubhoratri efanelekileyo kunye namanyathelo okukhusela umntu kufuneka athathwe ukuphepha ukudibanisa nolusu, ukuphefumla, okanye ukungeniswa kwekhompawundi. Iinkqubo zokusebenza ezikhuselekileyo zeekhemikhali kufuneka zilandelwe ngexesha lokusetyenziswa, kwaye ikhompawundi kufuneka igcinwe ngokufanelekileyo kwaye iphathwe ukuqinisekisa ukhuseleko lwebhubhoratri.
