Mawu Oyamba
3-Fluoro-4-nitrobenzoic acid ndi organic pawiri ndi mankhwala chilinganizo C7H4FNO4. Zotsatirazi ndizofotokozera zina, ntchito, njira zokonzekera ndi chidziwitso chachitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: Makristalo oyera kapena achikasu pang'ono, kapena chikasu chopepuka mpaka chachikasu chofiirira.
- Malo osungunuka: 174-178 digiri Celsius.
-Kuwira: 329 digiri Celsius.
-Kusungunuka: Kusungunuka mu mowa ndi organic solvents, monga ethanol, dimethylformamide ndi dichloromethane.
Gwiritsani ntchito:
- 3-Fluoro-4-nitrobenzoic acid ndi yofunika yapakatikati, yomwe imagwiritsidwa ntchito kwambiri popanga organic synthesis.
-Nthawi zambiri amagwiritsidwa ntchito popanga mankhwala komanso kaphatikizidwe ka utoto.
-Zidazi zitha kugwiritsidwanso ntchito ngati zopangira utoto, mankhwala ophera tizilombo komanso zophulika.
Njira Yokonzekera:
Njira yokonzekera 3-Fluoro-4-nitrobenzoic acid nthawi zambiri imakhala ndi izi:
1. 4-Nitrobenzoic acid imayendetsedwa ndi hydrogen fluoride kuti ipeze 3-nitro-4-fluorobenzoic acid.
2. Mankhwala omwe apezeka mu sitepe yapitayi amachitidwa ndi sulfuric acid kuti apeze 3-Fluoro-4-nitrobenzoic acid.
Zambiri Zachitetezo:
- 3-Fluoro-4-nitrobenzoic acid akhoza kukhumudwitsa maso, khungu, ndi kupuma thirakiti. Samalani kugwiritsa ntchito zida zodzitetezera panthawi yolumikizana.
- Iyenera kusungidwa mu chidebe chamdima, chowuma ndi chosindikizidwa, kutali ndi moto ndi oxidizing agents.
-Pogwiritsa ntchito komanso pogwira, ayenera kutsatira njira zotetezera, ndikusunga mpweya wabwino.
