Mawu Oyamba
2,5-Dichloro-3-nitropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: 2,5-Dichloro-3-nitropyridine ndi kristalo wopanda utoto wotumbululuka.
- Kusungunuka: Imasungunuka mu zosungunulira organic monga ethanol, dimethyl ether ndi chloroform, koma osasungunuka m'madzi.
- Kukhazikika: Pawiriyi imakhala yokhazikika kutentha kwa chipinda, koma imaphulika pa kutentha kwakukulu kapena kukhudzana ndi oxidizing amphamvu.
Gwiritsani ntchito:
- Mankhwala ophera tizirombo: Atha kugwiritsidwa ntchito ngati mankhwala ophera tizirombo ndipo amatha kuwononga tizirombo tina.
Njira:
The kaphatikizidwe njira ya 2,5-dichloro-3-nitropyridine zambiri zikuphatikizapo nitrification anachita ndi chlorination anachita. Mwa iwo, chikhalidwe kaphatikizidwe njira ndi nitrate 2,5-dichloropyridine ndi asidi nitric pamaso pa sulfuric acid. Njira ina ndikuchita 2-nitro-5-chloropyridine ndi acidic mkuwa bromidi kupanga 2,5-dichloro-3-nitropyridine.
Zambiri Zachitetezo:
- 2,5-Dichloro-3-nitropyridine ndi organic compound yomwe imayenera kusamaliridwa mosamala kuti isakhudze khungu, maso, ndi kupuma.
- Valani zida zodzitetezera zoyenera, kuphatikiza zovala zamaso, magolovu, ndi zishango zakumaso, mukamagwira ntchito.
- Mukamagwira ntchito, pewani kutulutsa mpweya, nkhungu kapena nthunzi ndikusunga mpweya wabwino.
- Mukakhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri ndipo funsani dokotala.
- Posunga, 2,5-dichloro-3-nitropyridine iyenera kusungidwa pamalo owuma, ozizira, opanda mpweya wabwino, kutali ndi kuyatsa ndi okosijeni.
