Mawu Oyamba
3, ndi organic pawiri ndi mankhwala chilinganizo C6H6Cl2N2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
-Maonekedwe: 3, ndi kristalo wopanda mtundu wotuwa wachikasu kapena ufa.
-Kusungunuka: Kutha kusungunuka m'madzi ndi organic solvents.
- Malo osungunuka: Malo ake osungunuka ndi 70-72 ° C.
-Kukhazikika: Imakhala yokhazikika kutentha, koma imatha kuwola pa kutentha kwakukulu.
Gwiritsani ntchito:
- 3, yomwe nthawi zambiri imagwiritsidwa ntchito ngati yapakatikati pakuphatikizika kwachilengedwe, imatha kugwiritsidwa ntchito kupanga zophatikiza ndi zochitika zachilengedwe.
-Itha kugwiritsidwanso ntchito pofufuza za mankhwala, kupanga mankhwala ophera tizilombo ndi zina.
Njira:
-Zochokera ku isocyanate zimatha kuchitidwa ndi 2-amino -3, 5-dichloro-6-methylbenzaldehyde kupanga 3 pyridine.
Zambiri Zachitetezo:
- 3, kawopsedwe ndi otsika, komabe ayenera kulabadira njira zodzitetezera, kupewa kukhudzana ndi khungu, maso ndi inhalation wa fumbi lake.
-Valani zida zodzitetezera zoyenera monga magolovesi a labu, magalasi oteteza chitetezo ndi masks oteteza mukamagwiritsa ntchito ndikugwira ntchito.
-Siyenera kumasulidwa ku chilengedwe.
-Posunga, sungani mu chidebe chotsekedwa, kutali ndi moto ndi oxidizing agents.
-Akamezedwa kapena kukomoka, pita kuchipatala msanga.
