3-Methoxy-2-nitropyridine (CAS # 20265-37-6) chiyambi
chilengedwe:
2-Nitro-3-methoxypyridine ndi yolimba yokhala ndi mawonekedwe oyera mpaka achikasu owala. Imakhala ndi fungo lamphamvu ndipo imayaka.
Kagwiritsidwe: Itha kugwiritsidwanso ntchito ngati zinthu zopangira utoto ndi utoto.
Njira yopanga:
2-Nitro-3-methoxypyridine ikhoza kukonzedwa pochita p-methoxyaniline ndi nitric acid. The yeniyeni kaphatikizidwe njira kungakhale nitration anachita wa methoxyaniline, kenako anachita analandira 2-nitro-3-methoxyaniline ndi acetone, ndipo potsiriza madzi m'thupi anachita.
Zambiri zachitetezo:
2-Nitro-3-methoxypyridine ikhoza kukhala poizoni m'thupi la munthu chifukwa imatha kuyambitsa kuyabwa pakhungu, maso, ndi kupuma. Njira zoyenera zotetezera ziyenera kuchitidwa panthawi yogwiritsira ntchito ndikugwira, monga kuvala magalasi otetezera, magolovesi, ndi masks. Onetsetsani kuti mupewe kukhudzana ndi zinthu zoyaka moto komanso kupewa kutulutsa fumbi, gasi kapena nthunzi. Chisamaliro chiyenera kuperekedwa pakukhala kutali ndi magwero a moto ndi malo otentha kwambiri pamene mukugwiritsa ntchito ndi kusunga.
