Mawu Oyamba
Ubwino:
4-Fluoro-2-nitrotoluene ndi ufa wa crystalline wopanda mtundu mpaka wachikasu womwe umakhala wolimba kutentha. Lili ndi fungo lamphamvu ndipo silisungunuka m'madzi, koma limasungunuka mosavuta mu zosungunulira za organic monga ethanol ndi ketoni.
Gwiritsani ntchito:
Njira:
Njira yokonzekera 4-fluoro-2-nitrotoluene imatha kupezeka ndi fluorination ya p-nitrotoluene. Makamaka, hydrogen fluoride kapena sodium fluoride angagwiritsidwe ntchito pochita ndi nitrotoluene mu zosungunulira organic kapena machitidwe kachitidwe komanso pa kutentha koyenera ndi kupsinjika.
Zambiri Zachitetezo:
Pali njira zina zachitetezo zomwe ziyenera kutsatiridwa mukamagwiritsa ntchito 4-fluoro-2-nitrotoluene. Ndi organic pawiri kuti penapake poyizoni ndi mkwiyo. Kupuma kwa mpweya wake kapena fumbi kuyenera kupewedwa panthawi yogwira ntchito ndipo mpweya wabwino uyenera kutetezedwa. Muzimutsuka mukangokhudza khungu kapena maso ndi madzi ambiri ndipo funsani malangizo achipatala. Posunga ndi kunyamula, kukhudzana ndi zinthu zoyaka moto kuyenera kupewedwa, ndipo zotengera ziyenera kutsekedwa mwamphamvu kuti zisakhale ndi moto ndi magwero a kutentha.
