Mawu Oyamba
2,5-Dichloronicotinic acid ndi organic pawiri ndi formula mankhwala C6H3Cl2NO2, amene amagwiritsa imidazole thumbnail kasinthidwe mu imidazolyl dye kapangidwe. Zotsatirazi ndi zina mwazinthu zazikulu za 2,5-Dichloronicotinic acid:
Chilengedwe:
-Maonekedwe: Choyera mpaka chotumbululuka chachikasu cholimba.
-Posungunuka: pafupifupi 207-208°C.
-Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka mu zosungunulira organic monga mowa, ether, chloroform, ndi zina.
-Kukhazikika: kukhazikika pa kutentha kwa chipinda.
Gwiritsani ntchito:
- 2,5-Dichloronicotinic acid angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic ndipo chimagwiritsidwa ntchito pokonza zosiyanasiyana organic mankhwala ndi mankhwala.
-Itha kugwiritsidwanso ntchito ngati ligand yomwe ili ndi ayoni achitsulo kuti apangitse kusintha kwazitsulo zachitsulo.
Kukonzekera:
- 2,5-Dichloronicotinic acid ikhoza kukonzedwa ndi chlorinating nicotinic acid. Njira yeniyeni ingakhale yochitira nicotinic acid ndi thionyl chloride pa kutentha kwakukulu, ndikutsatiridwa ndi kuzizira kwa crystallization kuti mupeze mankhwala.
Zambiri Zachitetezo:
- 2,5-Dichloronicotinic asidi ali ndi mlingo wina wa mkwiyo, kotero muyenera kulabadira chitetezo pa ntchito.
-Kawopsedwe ndi kuopsa kwa 2,5-Dichloronicotinic acid kumafuna kufufuza mozama ndi kuunika kuti mudziwe chitetezo chake ndi zoopsa zake. Chifukwa chake, pogwira ntchito ndikugwiritsa ntchito, tikulimbikitsidwa kutsatira njira zoyenera zotetezera ndikutengera njira zodzitetezera.
