Mawu Oyamba
4-Nitro-3-trifluoromethylaniline, yomwe imadziwikanso kuti TNB (Trinitrofluoromethylaniline), ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: Makristalo oyera mpaka achikasu owala kapena ufa
- Kusungunuka: kusungunuka pang'ono m'madzi, kusungunuka mu zosungunulira organic monga ethanol, acetone, etc.
- Kukhazikika: Kukhazikika pakuwala, kutentha ndi mpweya, koma kumakonda chinyezi ndi kuphulika
Gwiritsani ntchito:
- 4-Nitro-3-trifluoromethylaniline imagwiritsidwa ntchito kwambiri ngati gawo la oyambitsa ndi zophulika, mwachitsanzo, angagwiritsidwe ntchito m'malo mwa TNT (trinitrotoluene). Zili ndi mphamvu zophulika kwambiri komanso zokhazikika m'munda wa zophulika.
Njira:
- Kuchokera ku aniline, trifluoromethanesulfonic acid imatengedwa koyamba ndi cuprous bromide kupanga trifluoromethylaniline. Kenaka, trifluoromethylaniline imachitidwa ndi nitric acid, nitrobenzene imawonjezeredwa, ndipo pambuyo pa chithandizo cha nitrite acid, 4-nitro-3-trifluoromethylaniline pamapeto pake imapezeka.
Zambiri Zachitetezo:
- 4-Nitro-3-trifluoromethylaniline ndi chinthu chophulika ndipo chimatengedwa ngati chophulika ndipo chiyenera kugwiritsidwa ntchito mosamala.
- Pogwira ndikusunga, pewani kuyambitsa zoyatsira zilizonse kapena zoyaka zamagetsi.
- Pewani kukhudzana ndi zinthu zomwe zimatha kuyaka, ma okosijeni ndi zinthu zamchere zomwe zingayambitse zoopsa.
- Kukoka mpweya, kumeza, kapena kukhudza khungu ndi maso kungakhale ndi zotsatira zovulaza, zomwe zimafuna kuvala zida zoyenera zodzitetezera pochita opaleshoni.
