Mawu Oyamba
2,4-Dibromoaniline ndi organic compound. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
2,4-Dibromoaniline ndi kristalo wopanda mtundu womwe umasungunuka mu zosungunulira za organic monga ethanol, acetone ndi ether, komanso kusungunuka pang'ono m'madzi. Lili ndi fungo lamphamvu.
Gwiritsani ntchito:
2,4-Dibromoaniline ili ndi ntchito zosiyanasiyana mu organic synthesis. Itha kugwiritsidwa ntchito ngati kalambulabwalo wa utoto ndi utoto, ndipo itha kugwiritsidwanso ntchito pokonzekera zida zogwirira ntchito monga zowunikira za fulorosenti.
Njira:
Njira yokonzekera ya 2,4-dibromoaniline ikhoza kupezedwa ndi bromination reaction pakati pa aniline ndi bromine pansi pamikhalidwe yoyenera. Njira yokonzekera yomwe imagwiritsidwa ntchito nthawi zambiri ndikuwonjezera bromine ku aniline pansi pamikhalidwe yamchere, kenako ndikuchitapo kanthu ndi kutentha kosalekeza, ndikudutsa masitepe a kusefera, kutsuka ndi crystallization kuti mupeze zomwe mukufuna.
Zambiri Zachitetezo:
2,4-Dibromoaniline ndi mankhwala osokoneza bongo omwe angayambitse kupsa mtima ndi kutentha pokhudzana ndi khungu ndi maso. Magolovesi otetezera oyenerera, magalasi otetezera maso, ndi zovala zodzitetezera ziyenera kuvalidwa pochita opaleshoni kuti asapume mpweya. Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino ndikupewa kukhudzana ndi zinthu zomwe zimatha kuyaka. Chisamaliro chiyenera kutsatiridwa kuti chitsatire malamulo otetezeka okhudzana ndi chitetezo panthawi yosungira ndi kusamalira kuti tipewe kuyatsa ndi magetsi osasunthika.
