Mawu Oyamba
2-Chloro-4-fluorobenzyl bromide ndi organic compound yokhala ndi mankhwala C7H5BrClF. Ndi madzi opanda mtundu kapena opepuka achikasu amafuta omwe amatenthedwa bwino. Zotsatirazi ndizofotokozera zamtundu, kugwiritsa ntchito, kukonzekera ndi chitetezo cha 2-Chloro-4-fluorobenzyl bromide:
Chilengedwe:
-Maonekedwe: mafuta achikasu opanda mtundu kapena owala
-Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka mu zosungunulira za organic monga ethanol ndi dichloromethane
-Posungunuka: -10°C
-Kuwira: 112-114°C
-Kuchulukana: 1.646 g/mL
Gwiritsani ntchito:
2-Chloro-4-fluorobenzyl bromide nthawi zambiri imagwiritsidwa ntchito ngati chinthu chofunikira chapakati komanso chopangira mu organic synthesis. Ikhoza kugwiritsidwa ntchito popanga zinthu zina zakuthupi, monga mankhwala a heterocyclic, mankhwala ndi utoto.
Njira Yokonzekera:
2-Chloro-4-fluorobenzyl bromide ikhoza kukonzedwa pochita 2-chloro-4-fluorobenzyl mowa ndi hydrogen bromide. Choyamba, 2-chloro-4-fluorobenzyl mowa ndi esterified ndi hydrogen bromide pamaso pa maziko kupanga 2-chloro-4-fluorobenzyl bromide. Kenako, anayeretsedwa ndi m'zigawo ndi anaikira hydrochloric asidi ndi distillation kupeza chandamale mankhwala 2-Chloro-4-fluorobenzyl bromide.
Zambiri Zachitetezo:
Njira zotsatirazi zodzitetezera ziyenera kuwonedwa mukamagwiritsa ntchito 2-Chloro-4-fluorobenzyl bromide:
-Pewani kukhudzana ndi khungu, maso ndi mucous nembanemba. Mukakhudzana, yambani ndi madzi ambiri ndikupita kuchipatala.
-Panthawi ya ntchito, gwiritsani ntchito zida zodzitetezera zoyenera, monga magolovesi oteteza, magalasi oteteza komanso zovala zodzitchinjiriza.
-Pewani kulowetsa nthunzi kapena fumbi lake. Panthawi yogwira ntchito, ziyenera kutsimikiziridwa kuti zili pamalo abwino mpweya wabwino.
-Kusungirako kumayenera kusindikizidwa kuti zisakhudzidwe ndi ma oxidants ndi ma acid amphamvu / alkalis.
