Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C8H5F3N2. Zotsatirazi ndi zina za katundu, ntchito, kukonzekera ndi chitetezo zokhudzana ndi pawiri:
Chilengedwe:
-Mawonekedwe: Olimba akristalo opanda mtundu.
-Posungunuka: Pafupifupi 151-154°C.
-Powira: pafupifupi 305°C.
-Kusungunuka: Ndiko kusungunuka mu zosungunulira za polar monga ethanol, chloroform ndi dimethyl sulfoxide.
Gwiritsani ntchito:
- amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe organic kwa kaphatikizidwe wa mankhwala ogwirizana.
- Amagwiritsidwanso ntchito ngati zopangira zopangira mankhwala odana ndi khansa komanso mankhwala ophera tizilombo m'munda wamankhwala.
Njira:
Itha kupangidwa ndi njira zotsatirazi:
1. 3-cyano-4-trifluoromethylbenzenetonitrile imachitidwa ndi aminobenzene pansi pamikhalidwe yamchere.
2. Pambuyo pa kuyeretsedwa koyenera ndi chithandizo cha crystallization, chinthu chandamale chimapezeka.
Zambiri Zachitetezo:
-Pewani kukhudzana ndi ma oxidants, ma acid amphamvu ndi maziko amphamvu posunga ndikugwira.
-Chigawochi chikhoza kutulutsa mpweya wapoizoni ukatenthedwa ndi kuwotchedwa.
-Valani zida zodzitetezera zoyenera monga magalasi ndi magolovesi mukamagwiritsa ntchito.
