Mawu Oyamba
2,5-Difluorobenzyl bromide. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
Maonekedwe: 2,5-benzyl difluorobromide ndi madzi opanda mtundu kapena achikasu pang'ono.
Kachulukidwe: 1.74-1.76 g/cm³.
Kusungunuka: Kusungunuka mu zosungunulira organic monga ma alcohols, etha ndi zosungunulira zopanda polar.
Gwiritsani ntchito:
2,5-difluorobenzyl bromide imagwiritsidwa ntchito kwambiri ngati gawo lapakati komanso lopangira mu organic synthesis.
Mu kaphatikizidwe ka organic, nthawi zambiri amagwiritsidwa ntchito ngati fluorination ya olefins ndikusankha fluorination yamafuta onunkhira.
Njira:
Kukonzekera kwa 2,5-difluorobenzyl bromide kumatha kuchitika ndi izi:
Choyamba, 2,5-dibromobenzyl ndi trifluoroacetic acid amachitidwa ndi reflux mu mpweya condensate kapena madzi kukonzekera 2,5-difluorobenzylbromide njira.
Chopangidwa choyera cha 2,5-difluorobenzyl bromide chimasinthidwa, kusefa, ndikuwumitsa.
Zambiri Zachitetezo:
2,5-difluorobenzyl bromide ili ndi kawopsedwe kena, ndipo kusamala koyenera kuchitidwa mukamagwiritsa ntchito, kupewa kukhudzana ndi khungu, maso ndi kupuma.
Pakugwiritsa ntchito ndikukonzekera, zida zodzitetezera zoyenera monga magolovesi a mu labotale, magalasi, ndi masks oteteza ziyenera kuperekedwa.
Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino ndikupewa kukhudzana ndi zoyatsira ndi ma okosijeni.
Posunga, 2,5-difluorobenzyl bromide iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino, kutali ndi moto ndi zoyaka.
Chonde tsatirani machitidwe oyenera a labotale komanso malangizo oyendetsera bwino mukamagwiritsa ntchito 2,5-difluorobenzyl bromide.
