Nhanganyaya
Iyo organic compound ine kemikari formula C7H7N2O3.
Zvakasikwa:
ihombe ine ruvara rweyero yakachenuruka kusvika kune yero. Iyo inonyanya kunyungudika muzvinonyungudutsa uye isinganyanyi kunyungudika mumvura. Iyo ine imwe dhigirii yekupisa, uye kana ichipisa kana kusangana nemurazvo wakavhurika inoburitsa chepfu nitrogen oxides (NOx).
Shandisa:
Inowanzoshandiswa mune organic synthesis seyakakosha yepakati. Inogona kushandiswa mukugadzirwa kwemishonga yepyridine, yakadai semishonga yezvipembenene, zvinodhaka uye dhayi. Mukuwedzera, inogonawo kushandiswa se ligand yesimbi complexes.
Nzira:
Inowanzogadzirirwa nekuita kwe4-methyl-2-nitropyridine uye sodium hydroxide. Kuita kunowanzoitwa mune organic solvent uye chigadzirwa chinogona kuwanikwa.
Zvekuchengetedza
Inokuvadza muviri wemunhu. Kubata neganda kunogona kukonzera kusawirirana, uye inhalation yeguruva raro kana mhute inofanira kudzivirirwa. Pakubata, matanho akakodzera ekudzivirira anofanirwa kutorwa, sekupfeka magirovhosi, magirazi uye zvipfeko zvinodzivirira. Kana iri kushandiswa kana kuchengetedza, inofanira kunge iri kure nemoto uye oxidant. Munyaya yekudonha netsaona, siya nzvimbo inobuda nekukurumidza uye tora matanho ekuchenesa akakodzera.
