Nhanganyaya
Iyo organic compound ine kemikari formula C7H7N2O3. Iyi inotevera tsananguro yezvivakwa, mashandisiro, kugadzirira uye kuchengetedza ruzivo rwekomboni:
Zvakasikwa:
-Kuonekwa: Ikristaro yero kana hupfu.
-Solubility: Inenge isinganyungudika mumvura uye inonyungudika nyore nyore mune organic solvents senge ethanol, chloroform uye dimethyl sulfoxide.
-Kunyungudika: Nzvimbo yayo yekunyungudika inenge 135-137 degrees Celsius.
-Chemical properties: Iyo ine nitrogen-ine inonhuhwirira musanganiswa ine imwe kemikari yekuita basa.
Shandisa:
-Inogona kushandiswa seyepakati yekubatanidza mamwe ma organic compounds.
-Inogona kushandiswa seyakabikwa yemishonga yezvipembenene nemishonga yesora mumunda wekurima.
Nzira:
-inogona kugadzirirwa nekuita 2-methylpyridine ne nitric acid. Matanho chaiwo ndeaya anotevera: kunyungudutsa 2-methylpyridine mu ethanol, kuwedzera concentrated nitric acid, uye kuwana chigadzirwa kuburikidza nekristalllization mushure mekuita.
Zvekuchengetedza
-Kunyanya njodzi pakubata neganda, inhalation kana mushure mekudya.
-Dzivisa kubata kweganda uye inhalation paunenge uchisangana. Pfeka magirazi uye magirovhosi kana zvichidikanwa.
-Chengetedza nzira dzekushanda dzakachengeteka panguva yekubata nekuchengetedza uye kuvhara zvakanaka.
-kana zvichidikanwa, tarisa kuChemical Safety Data Sheet (MSDS) kuti uwane mamwe mashoko ekuchengetedza.
