Mawu Oyamba
2,4-difluorobenzylbromide ndi organic pawiri ndi mankhwala chilinganizo C7H5BrF2. Ndi madzi opanda mtundu okhala ndi fungo lamphamvu. Zotsatirazi ndizofotokozera zina mwazinthu, ntchito, njira ndi chitetezo cha 2,4-difluorobenzylbromide:
Chilengedwe:
-Maonekedwe: 2,4-difluorobenzylbromide ndi madzi opanda mtundu.
-Kusungunuka: Kutha kusungunuka ndi zosungunulira za organic, monga ethanol, chloroform ndi dimethylformamide.
Gwiritsani ntchito:
-2,4-difluorobenzylbromide angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic ndi ntchito synthesis wa mankhwala ena.
-Itha kugwiritsidwanso ntchito ngati zida zopangira mankhwala ophera tizilombo komanso mankhwala.
Njira:
-2,4-difluorobenzylbromide nthawi zambiri amakonzedwa pochita 2,4-difluorobenzoic acid ndi bromine.
-Njira yeniyeni yokonzekera imatha kusintha momwe zinthu zilili komanso ma reagents omwe amagwiritsidwa ntchito ngati pakufunika.
Zambiri Zachitetezo:
- 2,4-difluorobenzylbromide imakwiyitsa ndipo imafuna chidwi ndi njira zodzitetezera monga kuvala magolovesi ndi zovala zoteteza.
-Pewani kupuma movutikira, kukhudza khungu ndi maso mukamagwiritsa ntchito.
-Akapuma mwangozi kapena kukhudza mwangozi, wokhudzidwayo amayenera kuthamangitsidwa ndi mpweya wabwino ndikupatsidwa chithandizo chamankhwala.
-Posunga, sungani 2,4-difluorobenzylbromide kutali ndi moto ndi okosijeni kuti mupewe ngozi ya moto ndi kuphulika.
