Nhanganyaya
2-Chloro-4-methyl-3-nitropyridine is an organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Properties: 2-Chloro-4-methyl-3-nitropyridine haina ruvara kune yero yakasimba uye inonhuhwirira. Haina kunyungudika mumvura uye inonyungudika mune organic solvents senge ethanol uye dimethylformamide. Iine chepfu zvakanyanya.
Zvishandiso: 2-chloro-4-methyl-3-nitropyridine inonyanya kushandiswa sechinhu chakakosha chepakati uye chekugadzira mbishi mune organic synthesis. Inogonawo kushandiswa mukugadzirira kwesimbi complexes uye catalysts.
Kugadzirira nzira: Kugadzirira kwe2-chloro-4-methyl-3-nitropyridine kazhinji inotanga ne 2-chloro-4-methylpyridine. Kutanga, 2-chloro-4-methylpyridine yakabatwa neconcentrated nitric acid, uye ipapo chigadzirwa chacho chakanatswa uye chakanatswa kuti chiwane 2-chloro-4-methyl-3-nitropyridine.
Ruzivo Rwekuchengetedza: 2-Chloro-4-methyl-3-nitropyridine chinhu chine muchetura chinogona kukuvadza hutano kana chaiswa kana kukweshwa mumhute, hupfu, kana zvinogadzirisa. Inotsamwisa uye inokurudzira uye inofanira kudzivirirwa kubva pakubata neganda, maziso, uye nzira yekufema. Matanho akakodzera ekuchengetedza anofanirwa kutorwa pakubata kana kuchengetedza, sekupfeka midziyo yekudzivirira yakakodzera (semuenzaniso, magirovhosi, magirazi, uye masks). Paunenge uchishandiswa, chengetedza nzvimbo ine mhepo yakanaka uye usasangana nezvinhu zvinopisa. Chero tsvina ine 2-chloro-4-methyl-3-nitropyridine inofanira kuraswa maererano nemitemo yemunharaunda. Paunenge uchishandisa kana kubata iyi komputa, iyo yakakodzera kuchengetedza maitiro ekushandisa uye nhungamiro inofanirwa kuteedzerwa zvakanyanya.
