2-Amino-3-methyl-5-nitropyridine (CAS # 18344-51-9) Kev taw qhia
2-Amino-3-methyl-5-nitropyridine, tseem hu ua methylnitropyridine. Cov hauv qab no yog ib qho kev qhia txog qee yam ntawm cov khoom siv, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1. Cov tsos mob: 2-amino-3-methyl-5-nitropyridine yog dawb mus rau lub teeb daj crystalline hmoov los yog crystalline hmoov.
3. Solubility: Insoluble hauv dej, tab sis soluble hauv acidic media.
Siv:
1. Tshuaj reagent: 2-amino-3-methyl-5-nitropyridine tuaj yeem siv los ua cov hlau complexation reagent, catalyst rau organic synthesis thiab ib qho tseem ceeb tshuaj nruab nrab.
2. Cov khoom tawg thiab cov hmoov phom phom: Cov khoom sib xyaw no muaj qhov tawg siab heev, thiab nws tuaj yeem siv los npaj cov khoom tawg thiab cov hmoov phom.
3. Tshuaj tua kab: 2-amino-3-methyl-5-nitropyridine tuaj yeem siv los ua tshuaj tua kab thiab tshuaj tua kab.
Txoj kev:
2-Amino-3-methyl-5-nitropyridine tuaj yeem npaj los ntawm:
1. Nws yog tau los ntawm cov tshuaj tiv thaiv ntawm pyran molecule thiab nitric acid nyob rau hauv acidic tej yam kev mob.
2. Nws yog tau los ntawm reacting nrog formaldehyde thaum oxidizing ammonium nitrite los ntawm kev siv aminopyrrole.
Cov ntaub ntawv kev nyab xeeb:
1. 2-amino-3-methyl-5-nitropyridine muaj explosiveness siab thiab yog cov khoom siv hluav taws xob, yog li nws yuav tsum tau ceev kom deb ntawm cov nplaim taws thiab cov cua sov.
2. Cov plua plav uas nkag mus rau ntawm daim tawv nqaij thiab nqus tau cov khoom yuav ua rau khaus, yog li tsis txhob sib cuag ntawm daim tawv nqaij thiab nqus cov plua plav thaum ua haujlwm, thiab hnav hnab looj tes tiv thaiv thiab qhov ncauj qhov ntswg.
3. Cov txheej txheem kev ua haujlwm nyab xeeb yuav tsum tau ua raws li thaum tuav cov khoom siv thiab khaws cia kom zoo kom tsis txhob muaj xwm txheej thiab tsis zoo. Nws yuav tsum tau muab kaw thiab khaws cia thaum tsis siv.
