Mawu Oyamba
3,4-Difluorobsyl bromide ndi organic pawiri ndi mankhwala chilinganizo C7H5BrF2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
- 3,4-Difluorobenzyl bromide ndi madzi opanda mtundu.
-Ili ndi kachulukidwe ka 1.78g/cm³ komanso kuwira kwa madigiri 216-218 Celsius.
-Pa kutentha kwa chipinda, amatha kusungunuka muzitsulo za organic monga ether ndi chloroform.
Gwiritsani ntchito:
- 3,4-Difluorobenzyl bromide nthawi zambiri amagwiritsidwa ntchito ngati reagent mu organic synthesis. Itha kugwiritsidwa ntchito popanga ma organic compounds omwe ali ndi zida ndi zinthu zina.
-Itha kugwiritsidwanso ntchito ngati pakati pamankhwala ndi mankhwala ophera tizilombo.
Njira Yokonzekera:
Kukonzekera kwa -3,4-Difluorobenzyl bromide ikhoza kupezedwa pochita 3,4-difluorobenzaldehyde ndi sodium bromide pansi pazifukwa zoyenera kuchita.
Zambiri Zachitetezo:
- 3,4-Difluorobenzyl bromide imafuna chisamaliro chachitetezo pakusungirako ndikusamalira.
-Zisungidwe m'chidebe chotsekedwa, kupewa kukhudzana ndi mpweya ndi chinyezi.
-Valani magolovesi oteteza ndi magalasi oyenera mukamagwiritsa ntchito.
-Pewani kupuma, kutafuna kapena kukhudza khungu panthawi ya opaleshoni.
-Potaya zinyalala zimayenera kusamaliridwa ndikutayidwa motsatira malamulo okhudza dziko ndi dera.
Chonde onetsetsani kuti njira zotetezera zimatsatiridwa mosamalitsa mukamagwiritsa ntchito mankhwalawa, ndipo njira zodzitetezera zimatengedwa molingana ndi momwe zilili. Ngati muli ndi mafunso ena okhudza ntchito, chonde funsani katswiri kapena malangizo oyenera a labotale ya organic chemistry.
