Mawu Oyamba
P-ethylnitrobenzene (chidule: DEN) ndi organic compound. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha ethylnitrobenzene:
Ubwino:
1. Maonekedwe: P-ethylnitrobenzene ndi madzi opanda mtundu mpaka achikasu owala.
2. Kusungunuka: p-ethylnitrobenzene imasungunuka mu mowa ndi etha organic solvents.
Gwiritsani ntchito:
1. Kupanga zophulika: p-ethylnitrobenzene ikhoza kugwiritsidwa ntchito ngati zopangira zophulika zamphamvu kwambiri, monga kaphatikizidwe ka TNT (trinitrotoluene).
2. Chingwe chochotsa: P-ethylnitrobenzene imagwiritsidwanso ntchito ngati chigawo cha chingwe chophulika.
3. Kaphatikizidwe ka mankhwala: p-ethylnitrobenzene ndi yofunika kwambiri pakati pa organic synthesis ndipo ingagwiritsidwe ntchito popanga mankhwala ena.
Njira:
Kukonzekera kwa p-ethylnitrobenzene kungagwiritsidwe ntchito pochita styrene ndi asidi wa nitric kuti apange p-ethylaryl nitrate, kenaka kuthandizidwa ndi sulfuric acid kuti apeze p-ethylnitrobenzene.
Zambiri Zachitetezo:
1. P-ethylnitrobenzene ndi madzi oyaka ndipo ayenera kusungidwa kutali ndi moto ndi kutentha kwakukulu.
2. Pogwira p-ethylnitrobenzene, valani magolovesi oteteza ndi magalasi kuti musakhudze khungu ndi maso.
3. P-ethylnitrobenzene ili ndi poizoni wina ku chilengedwe ndipo imapewa kutayira m'madzi ndi dothi.
4. Njira zodzitetezera ziyenera kutsatiridwa posunga ndi kunyamula p-ethylnitrobenzene.
5. Poyesa p-ethylnitrobenzene, iyenera kuchitidwa mu labotale yodutsa mpweya wabwino kuti zisapume mpweya wake.
