Nhanganyaya
Mushonga we organic. Iine chimiro chemakemikari yeC5H3BrN4O2 uye molecular uremu we213.01g/mol. Iyi inotevera tsananguro yezvivakwa, mashandisiro, kugadzirira uye kuchengetedza ruzivo rwekomboni:
Zvakasikwa:
-Kuonekwa: Yero kune orenji crystal kana hupfu;
-Kunyungudika nzvimbo: anenge 117-120 madhigirii Celsius;
-Solubility: Inonyungudika zvishoma mumvura uye inonyungudika mune mamwe organic solvents senge alcohols, esters uye ketones.
Shandisa:
-Drug synthesis: Inowanzo shandiswa seyepakati mune organic synthesis uye inogona kushandiswa kugadzira akasiyana siyana zvinodhaka, dhayi, mishonga yezvipembenene uye mamwe makomisheni.
Kugadzirira nzira:
Kune nzira dzakawanda dzekugadzirira, uye inotevera ndeimwe yayo:
1. Kutanga, 3-bromo-5-nitropyridine inobatwa neammonia kuwana 3-nitro-5-aminopyridine.
2. Iyo inoguma 3-nitro-5-aminopyridine inobva yaitwa ne bromoalkane kana acetyl kuti iwane chigadzirwa chekupedzisira.
Zvekuchengetedza
Kazhinji haina njodzi kana ikashandiswa uye yakachengetwa nemazvo. Zvisinei, mitemo inotevera inofanira kutorwa:
-Pfeka midziyo yekudzivirira yakakodzera senge magurovhosi, magirazi uye majasi erabhoritari;
-Dzivisa kusangana neganda, muromo uye maziso. Kana pane kusangana, simbura pakarepo nemvura yakawanda;
-Shandisa uye chengetedza musanganiswa munzvimbo ine mhepo inofefetera kuti udzivise kufema gasi kana guruva;
-Usachengete kana kushandisa komboni nezvinhu zvinopisa;
-Kuverenga nekuchenjerera uye uteedzere kwakakodzera kuchengetedza kubata uye mirau yekurasa tsvina usati washandisa kana kurasa.
Ndokumbira utarise kuti ruzivo rwakapihwa pamusoro nderwekureva chete, uye mamiriro chaiwo anoda kunzwisiswa zvakare nekusimbiswa zvinoenderana nezvinodiwa chaizvo.
