Mawu Oyamba
2,5-Difluorobromobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera mwatsatanetsatane za katundu wake, ntchito, njira zopangira ndi chidziwitso cha chitetezo:
Ubwino:
2,5-Difluorobromobenzene ndi madzi opanda mtundu okhala ndi fungo lachilendo. Simasungunuka bwino m'madzi koma amasungunuka mu zosungunulira monga ma alcohols, ethers, ndi ketones.
Gwiritsani ntchito:
2,5-Difluorobromobenzene nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga organic. Angagwiritsidwenso ntchito ngati ligand kwa organometallic catalysts ndi ntchito m'malo zimachitikira, kugwirizana zimachitikira, etc. mu organic synthesis zimachitikira.
Njira:
Njira yokonzekera 2,5-difluorobromobenzene ndi yovuta ndipo nthawi zambiri imatha kupangidwa ndi zotsatirazi:
Pamaso pa bromobenzene, cuprous bromide ndi difluoromethanesulfonamide amachitidwa pamaso pa bromobenzene kupanga 2,5-difluorobromobenzene.
Phenylmagnesium bromide imayendetsedwa ndi cuprous fluoride kupanga 2,5-diphenyldifluoroethane, yomwe imayikidwa ndi bromination ndi iodination reaction kuti ipeze 2,5-difluorobromobenzene.
Zambiri Zachitetezo:
2,5-Difluorobromobenzene imakwiyitsa ndipo imatha kuyambitsa kusapeza bwino pokoka mpweya, kukhudzana ndi khungu, kapena kuyang'ana maso. Kukhudzana mwachindunji ndi khungu ndi maso kuyenera kupeŵedwa mukakumana, ndipo zida zodzitetezera monga magolovesi oteteza ndi magalasi ayenera kuvala ngati kuli kofunikira. Pokonzekera ndikugwiritsa ntchito, chidwi chiyenera kuperekedwa pa kupewa moto ndi kuphulika, ndikuonetsetsa kuti mpweya wabwino umakhala wabwino. Mukamagwiritsa ntchito ndikusunga, 2,5-difluorobromobenzene iyenera kusungidwa pa kutentha koyenera komanso mu chidebe chosindikizidwa, kutali ndi kuyatsa, kutentha ndi okosijeni.
