Nhanganyaya
2,5-Dichloro-3-nitropyridine is an organic compound. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
- Kuonekwa: 2,5-Dichloro-3-nitropyridine ikristaro isina ruvara kune yakachenuruka yero.
- Solubility: Inonyungudika muorganic solvents senge ethanol, dimethyl ether uye chloroform, asi isinganyanyike mumvura.
- Kugadzikana: Mushonga wacho wakagadzikana pakupisa kwekamuri, asi unoputika pakupisa kwakanyanya kana kusangana neakasimba oxidizing agents.
Shandisa:
- Mishonga yezvipembenene: Inogona kushandiswa semushonga wezvipembenene uye ine kudzora kwakanaka kune dzimwe tumbuyu.
Nzira:
Iyo synthesis nzira ye2,5-dichloro-3-nitropyridine inowanzobatanidza nitrification reaction uye chlorination reaction. Pakati pavo, nzira yechinyakare yekubatanidza ndeye nitrate 2,5-dichloropyridine ine nitric acid pamberi pe sulfuric acid. Imwe nzira ndeyekuita 2-nitro-5-chloropyridine ine acidic copper bromide kugadzira 2,5-dichloro-3-nitropyridine.
Zvekuchengetedza
- 2,5-Dichloro-3-nitropyridine musanganiswa weorganic unoda kubatwa nekuchenjerera kudzivirira kuti isasangana neganda, maziso, uye kufema system.
- Pfeka midziyo yekudzivirira yakakodzera, kusanganisira maziso ekudzivirira, magurovhosi, uye nhoo dzechiso paunenge uchishanda.
- Panguva yekushanda, dzivisa kufemesa magasi, mhute kana mhute uye chengetedza mhepo yakanaka.
- Kana ukasangana neganda kana maziso, simbura pakarepo nemvura yakawanda uye bvunza chiremba.
- Paunenge uchichengeta, 2,5-dichloro-3-nitropyridine inofanira kuchengetwa munzvimbo yakaoma, inotonhorera, ine mhepo yakanaka, kure nekupisa uye oxidants.
