Taw qhia
2-nitroaniline, tseem hu ua O-nitroaniline, 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 2-nitroaniline.
Zoo:
- Cov tsos mob: 2-nitroaniline yog cov xim daj lossis crystalline hmoov.
- Solubility: 2-nitroaniline yog soluble hauv ethanol, ether thiab benzene, thiab me ntsis soluble hauv dej.
Siv:
- Kev tsim cov dyes: 2-nitroaniline tuaj yeem siv rau hauv kev sib xyaw ntawm cov xim nruab nrab, xws li kev npaj ntawm aniline daj dye.
- Cov khoom tawg: 2-nitroaniline muaj cov khoom tawg thiab tuaj yeem siv los ua cov khoom siv rau cov khoom tawg thiab cov pyrotechnics.
Txoj kev:
- 2-nitroaniline tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm aniline nrog nitric acid. Cov tshuaj tiv thaiv kab mob feem ntau yog ua los ntawm qhov kub thiab txias thiab sulfuric acid yog siv los ua catalyst.
- Reaction equation: C6H5NH2 + HNO3 -> C6H6N2O2 + H2O
Cov ntaub ntawv kev nyab xeeb:
- 2-Nitroaniline yog cov khoom tawg uas tuaj yeem tshwm sim los ntawm kev raug hluav taws kub lossis kub kub. Nws yuav tsum tau khaws cia kom deb ntawm cov nplaim taws, qhov chaw tshav kub, hluav taws xob, thiab lwm yam.
- Hnav tsom iav thiab hnab looj tes tiv thaiv thaum ua haujlwm kom tsis txhob nqus plua plav lossis kov daim tawv nqaij, thiab zam kev tsis pom kev.
- Thaum nkag mus rau 2-nitroaniline, yaug tam sim ntawd nrog dej txaus thiab nrhiav kev kho mob rau kev kho mob.
