Mawu Oyamba
Ndi organic pawiri. Ili ndi mankhwala a C5H3BrN4O2 ndi molekyulu yolemera 213.01g/mol. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: Ndi kristalo wachikasu mpaka lalanje kapena ufa;
- Malo osungunuka: pafupifupi 117-120 madigiri Celsius;
-Solubility: Imasungunuka pang'ono m'madzi ndipo imasungunuka mu zosungunulira zina monga ma alcohols, esters ndi ketones.
Gwiritsani ntchito:
-Kaphatikizidwe ka mankhwala: Nthawi zambiri amagwiritsidwa ntchito ngati kaphatikizidwe ka organic ndipo angagwiritsidwe ntchito popanga mankhwala osiyanasiyana, utoto, mankhwala ophera tizilombo ndi mankhwala ena.
Njira Yokonzekera:
Pali njira zambiri zokonzekera, ndipo imodzi mwa izo ndi iyi:
1. Choyamba, 3-bromo-5-nitropyridine imachitidwa ndi ammonia kuti ipeze 3-nitro-5-aminopyridine.
2. Zotsatira za 3-nitro-5-aminopyridine zimachitidwa ndi bromoalkane kapena acetyl kuti apeze mankhwala omaliza.
Zambiri Zachitetezo:
Nthawi zambiri imakhala yotetezeka ikagwiritsidwa ntchito ndikusungidwa bwino. Komabe, zotsatirazi ziyenera kutsatiridwa:
-Valani zida zodzitetezera zoyenera monga magolovesi, magalasi ndi malaya a labu;
-Pewani kukhudza khungu, mkamwa ndi maso. Ngati pali kukhudzana, muzimutsuka nthawi yomweyo ndi madzi ambiri;
-Gwiritsirani ntchito ndikusunga pamalo opumira mpweya wabwino kuti musapume mpweya kapena fumbi;
-Osasunga kapena kugwiritsa ntchito pawiri ndi zinthu zoyaka;
- Werengani mosamala ndikutsata malamulo oyendetsera chitetezo ndi kutayira zinyalala musanagwiritse ntchito kapena kutaya.
Chonde dziwani kuti zomwe zaperekedwa pamwambapa ndi zongonena zokhazokha, ndipo zochitika zenizeni ziyenera kumveka bwino ndikutsimikiziridwa malinga ndi zosowa zenizeni.
