3-Methoxy-2-nitropyridine (CAS # 20265-37-6) Kev taw qhia
xwm:
2-Nitro-3-methoxypyridine yog cov khoom uas muaj xim dawb rau lub teeb daj crystalline. Nws muaj ib tug muaj zog tsw thiab yog flammable.
Kev Siv: Nws kuj tseem siv tau los ua cov khoom siv hluavtaws rau dyes thiab pigments.
Txoj kev tsim khoom:
2-Nitro-3-methoxypyridine tuaj yeem npaj los ntawm reacting p-methoxyaniline nrog nitric acid. Cov txheej txheem synthesis tshwj xeeb tuaj yeem yog nitration cov tshuaj tiv thaiv ntawm methoxyaniline, ua raws li cov tshuaj tiv thaiv ntawm 2-nitro-3-methoxyaniline nrog acetone, thiab thaum kawg lub cev qhuav dej.
Cov ntaub ntawv kev ruaj ntseg:
2-Nitro-3-methoxypyridine tej zaum yuav muaj tshuaj lom rau tib neeg lub cev vim nws tuaj yeem ua rau tawv nqaij, qhov muag, thiab ua pa. Kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum siv thiab tuav, xws li hnav looj tsom iav, hnab looj tes, thiab qhov ncauj qhov ntswg. Nco ntsoov zam kev sib cuag nrog cov khoom siv hluav taws xob thiab tsis txhob nqus cov plua plav, roj, lossis vapor. Kev ceev faj yuav tsum tau them rau kom deb ntawm qhov chaw hluav taws kub thiab qhov kub thiab txias thaum siv thiab khaws cia.
