Mawu Oyamba
5-fluoro-2-nitrobenzoic acid(5-fluoro-2-nitrobenzoic acid) ndi organic pawiri ndi mankhwala chilinganizo C7H4FNO4. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: 5-fluoro-2-nitrobenzoic asidi ndi woyera kapena woyera crystalline ufa.
-Posungunuka: Pafupifupi 172°C.
-Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka mu zosungunulira zina monga ma alcohols ndi esters.
Gwiritsani ntchito:
-Chemical kaphatikizidwe: 5-fluoro-2-nitrobenzoic asidi ndi ambiri ntchito organic kaphatikizidwe wapakatikati, amene angagwiritsidwe ntchito lithe ena organic mankhwala, monga mankhwala, mankhwala ndi utoto.
-Zolinga zofufuzira zasayansi: Chifukwa cha kapangidwe kake kamene kamakhala ndi magulu a fluorine ndi nitro, 5-fluoro-2-nitrobenzoic acid ili ndi mankhwala apadera ndipo imatha kugwiritsidwa ntchito pofufuza komanso kuyesa kwa labotale.
Njira:
Kukonzekera njira ya 5-fluoro-2-nitrobenzoic asidi zambiri akamagwira fluorination anachita 2-nitrobenzoic acid.
1. Choyamba, 2-nitrobenzoic acid imayendetsedwa ndi fluorinating agent (monga hydrogen fluoride kapena sodium fluoride).
2. Pambuyo pochita, 5-fluoro-2-nitrobenzoic acid mankhwala anapezedwa.
Tiyenera kukumbukira kuti panthawi yokonzekera, njira zoyenera zoyesera zoyesera ndi chitetezo ziyenera kugwiritsidwa ntchito kuti zitsimikizire chitetezo cha kuyesera.
Zambiri Zachitetezo:
- 5-fluoro-2-nitrobenzoic acid amaonedwa kuti ndi otetezeka kwambiri pazochitika zonse, koma amafunikabe kusamaliridwa mosamala ndikutsatira njira zoyenera zoyesera.
-Pokhudzana ndi mankhwalawa, kukhudzana kwachindunji pakhungu ndi kupuma fumbi lake kuyenera kupewedwa.
-Pogwiritsa ntchito ndi kusungirako, chonde tetezani bwino zida za labotale, ndipo tsatirani malangizo okhudzana ndi chitetezo.
-Pakachitika ngozi kapena kuganiziridwa kuti ndi poizoni, funsani kuchipatala mwachangu ndikubweretsa zidziwitso zachitetezo chapagulu.
