Taw qhia
2-Methoxy-4-nitroaniline yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 2-Methoxy-4-nitroaniline yog cov xim daj lossis crystalline hmoov.
- Solubility: Nws yog me ntsis soluble hauv ethanol thiab ether thiab yuav luag insoluble hauv dej.
- Kev ruaj ntseg: 2-Methoxy-4-nitroaniline yog qhov ruaj khov ntawm chav tsev kub, tab sis thaum raug tshav ntuj los yog kub kub, nws yuav decompose los tsim cov pa phem.
Siv:
- Cov khoom tawg: nyob rau hauv lub xub ntiag ntawm lawv pawg nitro, 2-methoxy-4-nitroaniline kuj tseem siv tau rau hauv kev npaj cov khoom tawg. Txawm li cas los xij, nws yog qhov rhiab heev thiab txaus ntshai, yog li nws yuav tsum tau ceev faj.
Txoj kev:
- 2-Methoxy-4-nitroaniline tuaj yeem npaj los ntawm nitrification ntawm para-formaniline. Formaniline yog yaj nyob rau hauv concentrated sulfuric acid, ces concentrated nitric acid yog maj ntxiv thiab txias, thiab thaum kawg cov khoom yog sib cais.
Cov ntaub ntawv kev nyab xeeb:
- Toxicity: 2-Methoxy-4-nitroaniline yog ib yam tshuaj lom uas tuaj yeem ua rau muaj tshuaj lom yog tias nqus tau, noj, lossis sib cuag nrog daim tawv nqaij.
- Hluav Taws Xob Hluav Taws Xob: 2-Methoxy-4-nitroaniline muaj qhov phom sij tawg siab heev thiab kev sib cuag nrog cov khoom siv hluav taws xob, oxidants lossis cov khoom siv hluav taws xob yuav tsum raug zam.
- Lwm yam kev tiv thaiv kev nyab xeeb: Thaum tuav 2-methoxy-4-nitroaniline, cov khoom siv tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav. Kev saib xyuas yuav tsum tau ua thaum tus txheej txheem los tiv thaiv kev tso pa tawm ntawm cov pa phem thiab tsis txhob sib cuag nrog lub qhov muag, tawv nqaij thiab ua pa. Ua tib zoo saib xyuas qhov cua ntawm chav tsev kub thiab kom deb ntawm hluav taws thaum siv thiab khaws cia.
