Taw qhia
P-ethylnitrobenzene (lub npe: DEN) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ethylnitrobenzene:
Zoo:
1. Cov tsos mob: P-ethylnitrobenzene yog xim tsis muaj xim rau lub teeb daj.
2. Solubility: p-ethylnitrobenzene yog soluble hauv cawv thiab ether organic solvents.
Siv:
1. Kev tsim cov khoom tawg: p-ethylnitrobenzene tuaj yeem siv los ua cov khoom siv hluav taws xob siab, xws li kev sib xyaw ntawm TNT (trinitrotoluene).
2. Detonating qaum: P-ethylnitrobenzene kuj yog siv los ua ib feem ntawm lub detonating qaum.
3. Chemical synthesis: p-ethylnitrobenzene yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab tuaj yeem siv los ua ke rau lwm cov tebchaw.
Txoj kev:
Kev npaj ntawm p-ethylnitrobenzene tuaj yeem siv los ua cov tshuaj styrene nrog nitric acid los tsim p-ethylaryl nitrate, thiab tom qab ntawd kho nrog sulfuric acid kom tau txais p-ethylnitrobenzene.
Cov ntaub ntawv kev nyab xeeb:
1. P-ethylnitrobenzene yog cov kua ua kua thiab yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab kub.
2. Thaum tuav p-ethylnitrobenzene, hnav hnab looj tes tiv thaiv thiab tsom iav kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
3. P-ethylnitrobenzene muaj qee yam toxicity rau ib puag ncig thiab tsis txhob tso tawm rau hauv dej thiab av.
4. Yuav tsum ceev faj thaum khaws cia thiab nqa p-ethylnitrobenzene.
5. Thaum sim nrog p-ethylnitrobenzene, nws yuav tsum tau ua nyob rau hauv ib tug zoo-ventilated kuaj kom tsis txhob nqus nws vapors.
