Mawu Oyamba

2-Hydroxy-3-nitropyridine ndi organic pawiri ndi molecular formula C5H4N2O3 ndi structural formula HO-NO2-C5H3N.

Chilengedwe:

2-Hydroxy-3-nitropyridine ndi galasi lachikasu lomwe limatha kusungunuka muzinthu zina zosungunulira monga ethanol ndi dimethylformamide. Ili ndi malo otsika osungunuka ndi otentha.

Gwiritsani ntchito:

2-Hydroxy-3-nitropyridine amagwiritsidwa ntchito kwambiri popanga organic synthesis reaction, monga ma reagents kapena zopangira. Ikhoza kutenga nawo mbali pamachitidwe osiyanasiyana a mankhwala, monga kuchepetsa kachitidwe ndi esterification reaction.

Njira Yokonzekera:

Kukonzekera kwa 2-Hydroxy-3-nitropyridine kumatha kupezedwa ndi nitration reaction. Choyamba, pyridine imakhudzidwa ndi asidi wa nitric kuti apange 2-nitropyridine. 2-Nitropyridine imasinthidwa ndi maziko okhazikika kupanga 2-Hydroxy-3-nitropyridine.

Zambiri Zachitetezo:

2-Hydroxy-3-nitropyridine ndi mankhwala ndipo ayenera kugwiritsidwa ntchito mosamala. Zitha kukhala zokhumudwitsa m'maso, pakhungu komanso m'mapapo. Kukhudzana ndi inhalation wa pawiri ayenera kupewa ntchito. Gwiritsani ntchito zida zodzitetezera monga magalavu oteteza mankhwala ndi magalasi mukamagwiritsa ntchito. Kuphatikiza apo, ntchitoyi iyenera kuchitidwa pamalo abwino mpweya wabwino kuti zitsimikizire chitetezo.
