Mawu Oyamba
4-Iodo-3-nitrobenzoic acid ndi organic pawiri ndi mankhwala formula C7H4INO4. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: 4-Iodo-3-nitrobenzoic acid ndi ufa wachikasu wa crystalline.
- Malo osungunuka: pafupifupi 230 ° C.
-Kusungunuka: Kusungunuka mu ethanol, etha ndi chloroform, osasungunuka m'madzi.
Gwiritsani ntchito:
- 4-Iodo-3-nitrobenzoic acid amagwiritsidwa ntchito makamaka ngati wapakatikati mu kaphatikizidwe ka organic.
-Ndi zofunika zopangira kwa synthesis wa mankhwala ndi mankhwala.
-Itha kugwiritsidwanso ntchito popanga zigawo zotulutsa kuwala mu organic electroluminescent zida (OLED).
Njira Yokonzekera:
Pali njira zambiri zopangira 4-Iodo-3-nitrobenzoic acid, imodzi mwazomwe zimagwiritsidwa ntchito popanga nitration ya iodobenzoic acid. Zokonzekera zenizeni ndi izi:
1. Sungunulani iodobenzoic acid mu chigawo cha nitric acid.
2. Pang'onopang'ono onjezerani sulfuric acid pa kutentha kochepa ndikuyambitsanso.
3. Pambuyo zomwe zimachitikira kwa nthawi, mankhwala mu njira yothetsera amasiyanitsidwa ndi kusefera kapena crystallization.
4. 4-Iodo-3-nitrobenzoic acid potsiriza inayeretsedwa mwa kutsukidwa ndi zosungunulira zoyenera ndi crystallization.
Zambiri Zachitetezo:
- 4-Iodo-3-nitrobenzoic acid ndi organic pawiri. Njira zodzitetezera ziyenera kuchitidwa mukazigwiritsa ntchito, monga kuvala magolovesi ndi magalasi oteteza maso.
-Pawiriyi imakhala ndi dzimbiri pamlingo wina wake, pewani kukhudzana ndi khungu komanso kupuma.
-Panthawi ya opareshoni, samalani kuti musagwirizane ndi ma oxidants amphamvu komanso othandizira kuti mupewe zoopsa.
-Pakasungirako, ziyenera kusungidwa pamalo ozizira, owuma, opanda mpweya wabwino, olekanitsidwa ndi zinthu zoyaka ndi zoyaka.
-Ngati kukhudzana kwachitika, sukani nthawi yomweyo malo omwe akhudzidwawo ndi madzi ambiri ndikupempha thandizo lachipatala.
