Mawu Oyamba
3-Chloro-4-methylpyridine ndi organic pawiri. Makhalidwe ake ndi awa:
1. Mawonekedwe:3-chloro-4-methylpyridinendi madzi achikasu owala opanda mtundu.
2. Kuchulukana: 1.119 g/cm³
4. Kusungunuka: 3-chloro-4-methylpyridine imasungunuka m'madzi ambiri osungunulira komanso osasungunuka m'madzi.
Ntchito zazikulu za 3-chloro-4-methylpyridine ndi izi:
1. Kaphatikizidwe ka kusintha kwazitsulo zazitsulo: Ndikofunikira kwapakatikati komwe kumagwiritsidwa ntchito pogwirizanitsa chemistry ya kaphatikizidwe ka amino alcohols, amino alkates, ndi mankhwala ena a nitrogen heterocyclic.
2. Mankhwala ophera tizilombo: 3-chloro-4-methylpyridine angagwiritsidwe ntchito ngati pakati pa mankhwala ena ophera tizilombo ndi herbicides.
Njira yokonzekera 3-chloro-4-methylpyridine nthawi zambiri imakhala ndi izi:
1. Nitroation reaction ya pyridine: pyridine imayendetsedwa ndi nitric acid ndi sulfuric acid kuti ipeze 3-nitropyridine.
2. Kuchepetsa kuchepetsa: 3-nitropyridine imachitidwa ndi owonjezera sulfoxide ndi kuchepetsa wothandizira (monga zinc ufa) kuti apeze 3-aminopyridine.
3. Kuchita kwa chlorine: 3-aminopyridine imakhudzidwa ndi thionyl chloride kuti ipeze 3-chloro-4-methylpyridine.
Zambiri zokhudzana ndi chitetezo cha 3-chloro-4-methylpyridine ndi izi:
1. Sensitization: Atha kukhala ndi allergenic reaction kwa anthu ena.
2. Kupsa mtima: Kukhoza kukhala ndi zotsatira zokhumudwitsa m'maso, kupuma komanso khungu.
3. Kawopsedwe: Ndiwowopsa ku thanzi la munthu ndipo ayenera kutsatira njira zoyendetsera chitetezo.
4. Kusungirako: Iyenera kusungidwa mu chidebe chotchinga mpweya, kutali ndi kuyatsa ndi okosijeni, komanso kutali ndi kukhudzana ndi mpweya.
Mukamagwiritsa ntchito 3-chloro-4-methylpyridine, tsatirani njira zodzitetezera monga kuvala zovala zoteteza maso, magolovesi ndi zovala zodzitchinjiriza, ndikuwonetsetsa kuti zikugwiritsidwa ntchito pamalo abwino mpweya wabwino. Mukakhudzana mwangozi kapena kupumira mpweya, funsani kuchipatala mwamsanga ndikuwonetsani Chidziwitso cha Chitetezo cha mankhwalawo kwa dokotala wanu.
