Mawu Oyamba
3-Nitropyridine(3-Nitropyridine) ndi organic pawiri ndi mankhwala chilinganizo C5H4N2O2. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha 3-Nitropyridine:
Chilengedwe:
-Maonekedwe: 3-Nitropyridine ndi kristalo woyera mpaka wotumbululuka wachikasu kapena ufa wonyezimira.
- Malo osungunuka: pafupifupi 71-73 ° C.
-Powira: Pafupifupi 285-287 ℃.
- Kachulukidwe: pafupifupi 1.35g/cm³.
-Kusungunuka: kusungunuka kochepa m'madzi, kusungunuka mu zosungunulira organic monga ethanol, acetone, etc.
Gwiritsani ntchito:
- 3-Nitropyridine angagwiritsidwe ntchito ngati organic synthesis wapakatikati kwa synthesis zosiyanasiyana organic mankhwala.
-Itha kugwiritsidwanso ntchito ngati utoto wa fulorosenti komanso chojambula cha photosensitizer.
-Paulimi, itha kugwiritsidwa ntchito ngati mankhwala ophera tizilombo komanso ma fungicides.
Njira:
- Njira yayikulu yokonzekera imapezeka ndi nitration ya 3-picolinic acid. Choyamba, 3-picolinic acid imachitidwa ndi nitric acid ndi nitrate pansi pamikhalidwe yoyenera kuti ipange 3-Nitropyridine.
- Njira zina zotetezera zimafunika panthawi yokonzekera, kuphatikizapo kupewa kukhudzana ndi khungu ndi maso, kukhala kutali ndi magwero a moto ndi mpweya wabwino.
Zambiri Zachitetezo:
- 3-Nitropyridine ndi organic pawiri. Njira zotsatirazi zodzitetezera ziyenera kutsatiridwa mukamagwiritsa ntchito ndikusunga:
-Kukwiyitsa khungu ndi maso, pewani kukhudzana mukamagwiritsa ntchito. Mukakhudza, muzimutsuka nthawi yomweyo ndi madzi ambiri.
- Zingakhale zoipa kwa kupuma thirakiti ndi m`mimba dongosolo, choncho kupewa inhalation ndi kudya pa ntchito.
-Pakasungira ndikugwiritsa ntchito, amafunika kukhala otsika, owuma komanso osindikizidwa.
-Kutaya zinyalala kukuyenera kutsata malamulo a m'deralo ndipo zisatayidwe mwachindunji ku gwero la madzi kapena chilengedwe.
Chonde dziwani kuti izi zikupereka chidziŵitso chonse, ndipo ndondomeko za labotale ndi zambiri zachitetezo ziyenera kutsatiridwa molingana ndi njira zoyenera zotetezera labotale yamankhwala. Pazofuna zapadera zoyesera ndi mawonekedwe ogwiritsira ntchito, chonde funsani akatswiri apadera a labotale yamankhwala kapena katswiri pankhaniyi.
