Nhanganyaya
3-Nitropyridine(3-Nitropyridine) is an organic compound ine kemikari formula C5H4N2O2. Izvi zvinotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye3-Nitropyridine:
Zvakasikwa:
-Kuonekwa: 3-Nitropyridine ichena kune yakachenuruka yekristaro kana crystal powder.
-Kunyungudika: inenge 71-73°C.
-Poindi yekubikira: Inenge 285-287 ℃.
-Density: inenge 1.35g/cm³.
-Solubility: yakaderera solubility mumvura, soluble mune organic solvents senge ethanol, acetone, nezvimwe.
Shandisa:
- 3-Nitropyridine inogona kushandiswa seyakagadzirwa organic synthesis yepakati pakugadzirwa kweakasiyana organic komisheni.
-Inogona zvakare kushandiswa sedhayi refluorescent uye photosensitizer.
-Mukurima, inogona kushandiswa seyakabikwa yemishonga yezvipembenene uye fungicides.
Nzira:
-Iyo nzira huru yekugadzirira inowanikwa ne nitration ye 3-picolinic acid. Kutanga, 3-picolinic asidhi inobatwa ne nitric acid uye nitrate pasi pemamiriro ekuita akakodzera kuti ibudise 3-Nitropyridine.
-Mamwe matanho ekuchengetedza anodiwa panguva yekugadzirira, kusanganisira kudzivisa kusangana neganda nemaziso, kuchengetedza kure nemoto uye mhepo yakanaka.
Zvekuchengetedza
- 3-Nitropyridine is an organic compound. Aya anotevera ekuchengetedza ekuchengetedza anofanirwa kutariswa panguva yekushandiswa uye kuchengetedza:
-Kushungurudza ganda nemeso, dzivisa kubata kana uchishandisa. Kana wasangana, sukurudza pakarepo nemvura yakawanda.
-Inogona kuva inokuvadza kumhepo yekufema uye digestive system, saka dzivisa kufema uye kunwa panguva yekushanda.
-Panguva yekuchengetedza uye kushandiswa, inoda kuchengetwa yakaderera, yakaoma uye yakavharwa.
-Kurasa tsvina kunofanirwa kutevedzera mirau yenzvimbo uye haifanirwe kuburitswa yakananga mutsime remvura kana nharaunda.
Ndokumbira utarise kuti ruzivo urwu runopa sumo yakajairwa, uye maitiro chaiwo emurabhoritari uye ruzivo rwekuchengetedza rwunoda kutevedzwa zvinoenderana nemaitiro akakodzera ekuchengetedza marabhoritari emakemikari. Nezvezvido zvekuyedza uye mamiriro ekushandisa, ndapota bvunza yakasarudzika makemikari marabhoritari kana nyanzvi mumunda.
