Intshayelelo
I-3-nitro-4-fluorobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokwenza, kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Ikristale emhlophe eqinileyo.
- Ukunyibilika: akunyibiliki emanzini, kunyibilika kancinane kwiziselo ezinxilisayo kunye ne-ethers.
Sebenzisa:
- I-3-Nitro-4-fluorobenzoic acid isetyenziswa ikakhulu njengento ephakathi kwiimpendulo ze-organic synthesis.
Indlela:
- I-3-nitro-4-fluorobenzoic acid inokufumaneka ngokusabela endaweni ye-p-nitrotoluene. Amanyathelo athile kukuqala endaweni ye-fluorine ye-nitrotoluene phantsi kweemeko ze-acidic ukufumana i-3-nitro-4-fluorotoluene, kwaye emva koko i-oxidation yokusabela ngakumbi ukufumana i-3-nitro-4-fluorobenzoic acid.
Ulwazi ngoKhuseleko:
- I-3-nitro-4-fluorobenzoic acid ingaba yityhefu ebantwini, iyacaphukisa amehlo kunye nolusu.
- Xa usebenzisa, kunqande ukudibana ngqo nolusu kunye namehlo, kwaye usebenzise iiglavu zokhuselo kunye nezibuko ukuba kukho imfuneko.
- Ngexesha lokugcinwa, kufuneka igcinwe kwindawo emnyama, eyomileyo, nepholileyo, kude nomlilo kunye ne-oxidants.
- Xa ulahla inkunkuma, nceda uthobele imimiselo yokhuseleko efanelekileyo ukuthintela ukungcoliseka kwendalo.
