Mawu Oyamba
2-Cyano-3,5-dichloropyridine ndi organic pawiri ndi mankhwala formula C6H2Cl2N2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
2-Cyano-3,5-dichloropyridine ndi yopanda mtundu kapena yotumbululuka yachikasu. Imakhala ndi kusinthasintha kochepa pa kutentha kwapakati. Lili ndi kusungunuka kochepa m'madzi komanso kusungunuka kwakukulu mu zosungunulira za organic monga ethanol ndi dimethylformamide.
Gwiritsani ntchito:
2-Cyano-3,5-dichloropyridine ili ndi mitundu yambiri yogwiritsira ntchito mu organic synthesis. Itha kugwiritsidwa ntchito ngati wapakatikati popanga zinthu zosiyanasiyana zachilengedwe (monga mankhwala, utoto ndi mankhwala ophera tizilombo). Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati zinthu pakufufuza ma organic light-emitting diode (OLED) ndi ma crystal amadzimadzi.
Njira Yokonzekera:
2-Cyano-3,5-dichloropyridine ikhoza kukonzedwa pogwiritsa ntchito njira zosiyanasiyana zopangira. Njira yodziwika bwino yopangira ma pyridine ndi cyanide, ndikutsatiridwa ndi chlorination kuti mupeze mankhwalawo.
Zambiri Zachitetezo:
2-Cyano-3,5-dichloropyridine ikhoza kuonedwa kuti ndi yovulaza nthawi zonse. Zingakhale zokwiyitsa kupuma, maso ndi khungu. Pogwiritsidwa ntchito, ayenera kutenga njira zodzitetezera, monga kuvala magolovesi ndi magalasi. Pewani kukhudzana ndi ma oxidizing agents ndi ma asidi amphamvu posunga ndikugwira. Ngati zavumbulutsidwa kapena kukomoka, pitani kuchipatala mwachangu.
