Mawu Oyamba
3-nitro-4-fluorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira, ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: Makristalo oyera olimba.
- Kusungunuka: kosasungunuka m'madzi, kusungunuka pang'ono muzoledzeretsa ndi ethers.
Gwiritsani ntchito:
- 3-Nitro-4-fluorobenzoic asidi zimagwiritsa ntchito ngati wapakatikati mu organic synthesis zimachitikira.
Njira:
- 3-nitro-4-fluorobenzoic asidi angapezeke m'malo zimene p-nitrotoluene. Masitepe enieni ndi choyamba fluorine m'malo nitrotoluene pansi acidic zinthu kupeza 3-nitro-4-fluorotoluene, ndiyeno zina makutidwe ndi okosijeni anachita kupeza 3-nitro-4-fluorobenzoic acid.
Zambiri Zachitetezo:
- 3-nitro-4-fluorobenzoic acid ikhoza kukhala poizoni kwa anthu, imakwiyitsa maso ndi khungu.
- Mukamagwiritsa ntchito, pewani kukhudza khungu ndi maso, ndipo gwiritsani ntchito magolovesi oteteza ndi magalasi ngati kuli kofunikira.
- Pakusungirako, ziyenera kusungidwa pamalo amdima, owuma komanso ozizira, kutali ndi moto ndi okosijeni.
- Potaya zinyalala, chonde tsatirani malamulo okhudzana ndi chitetezo kuti mupewe kuipitsidwa kwa chilengedwe.
