Nhanganyaya
3,4-Difluorobsyl bromide is an organic compound ine chemical formula C7H5BrF2. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
- 3,4-Difluorobenzyl bromide imvura isina ruvara.
-Iine density ye1.78g/cm³ uye kuvira kwe216-218 degrees Celsius.
-Pakupisa kwekamuri, inogona kunyungudika mune organic solvents senge ether uye chloroform.
Shandisa:
- 3,4-Difluorobenzyl bromide inowanzoshandiswa se reagent mu organic synthesis. Inogona kushandiswa kugadzira organic komisheni ine chaiyo zvimiro uye zvimiro.
-Inogonawo kushandiswa sepakati mumishonga uye mishonga yezvipembenene.
Kugadzirira nzira:
Kugadzirira kwe -3,4-Difluorobenzyl bromide inogona kuwanikwa kuburikidza nekuita 3,4-difluorobenzaldehyde ne sodium bromide pasi pemamiriro akakodzera ekuita.
Zvekuchengetedza
- 3,4-Difluorobenzyl bromide inoda kutariswa kwekuchengetedza kuchengetedza panguva yekuchengetedza nekubata.
-Inofanira kuchengetwa mumudziyo wakavharwa, dzivisa kusangana nemhepo uye unyoro.
-Pfeka magurovhosi ekudzivirira akakodzera uye magirazi paunenge uchishandisa.
-Dzivisa kufema, kutsenga kana kubata ganda panguva yekushanda.
-Pakurasa tsvina, inofanira kubatwa uye kuraswa maererano nemitemo yenyika uye yenharaunda.
Ndokumbira utarise kuti nzira dzekuchengetedza dzakakodzera dzinotevedzwa zvakanyanya paunenge uchishandisa iyi komputa, uye matanho akakodzera ekudzivirira anotorwa zvinoenderana nemamiriro chaiwo. Kana iwe uine mimwe mibvunzo yekushandisa, ndapota bvunza nyanzvi kana nhungamiro yakakodzera yeorganic chemistry laboratory.
