1. Chitarisiko:3-chloro-4-methylpyridineimvura isina ruvara kuenda kuchiedza yero.
2. Kuwanda: 1.119 g/cm³
4. Solubility: 3-chloro-4-methylpyridine inonyunguduka mune zvakawanda organic solvents uye isingasviki mumvura.
Iko kushandiswa kukuru kwe3-chloro-4-methylpyridine ndeiyi inotevera:
1. Synthesis of transition metal complexes: Inokosha yepakati inoshandiswa mukugadzirisa kemikari yekugadzirwa kweamino alcohols, amino alkates, uye mamwe nitrogen heterocyclic compounds.
2. Mishonga yezvipembenene: 3-chloro-4-methylpyridine inogona kushandiswa sepakati mune zvimwe zvipembenene uye mishonga yesora.
Nzira yekugadzirira 3-chloro-4-methylpyridine inowanzobatanidza matanho anotevera:
1. Nitroation reaction yepyridine: pyridine inobatwa ne concentrated nitric acid uye sulfuric acid kuti iwane 3-nitropyridine.
2. Kuderedza maitiro: 3-nitropyridine inobatwa nehuwandu hwe sulfoxide uye inoderedza mumiririri (yakadai se zinc powder) kuwana 3-aminopyridine.
3. Chlorination reaction: 3-aminopyridine inobatwa ne thionyl chloride kuti iwane 3-chloro-4-methylpyridine.
Ruzivo rwekuchengetedza rwakakodzera rwe3-chloro-4-methylpyridine ndeichi:
1. Sensitization: Inogona kunge iine allergenic maitiro kune mamwe marudzi.
2. Kushatirwa: Inogona kuva nemigumisiro inogumbura pameso, maitiro ekufema uye ganda.
3. Toxicity: Iine muchetura kuhutano hwevanhu uye inofanirwa kutevedzera nzira dzekuchengetedza dzakakodzera.
4. Kuchengeta: Inofanirwa kuchengetwa mumudziyo usingapindi mhepo, kure nekupisa uye maoxidants, uye kure nekusangana nemhepo.
Paunenge uchishandisa 3-chloro-4-methylpyridine, tevera mapuroteni akakodzera ekuchengetedza akadai sekupfeka maziso ekudzivirira, magirovhosi uye zvipfeko zvekudzivirira, uye ona kuti inoshandiswa munzvimbo ine mhepo inofefetera. Kana wasangana netsaona kana kufemerwa, tsvaga kurapwa nekukurumidza uye ratidza chigadzirwa Chekuchengetedza Data Sheet kuna chiremba wako.
