Nhanganyaya
2-Fluoro-4-bromobenzyl bromide is an organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
- Chitarisiko: 2-Fluoro-4-bromobenzyl bromide imvura isina ruvara kune yakachenuruka yero.
- Solubility: Inonyungudika muorganic solvents senge madoro uye ether, asi isinganyungudika mumvura.
Shandisa:
- 2-Fluoro-4-bromobenzyl bromide inowanzoshandiswa sechinhu chakakosha chepakati mune organic synthesis.
- Iyi komputa inogona zvakare kushandiswa seyakagadzirwa zvinhu zvinokonzeresa uye surfactants.
Nzira:
Nzira yekugadzirira ye2-fluoro-4-bromobenzyl bromide ndeyotevera:
- Reaction ye 2-bromobenzyl doro ne 2,4-difluorobenzoic acid, catalyzed nealkali, panguva yakakodzera tembiricha uye nguva mamiriro.
- Mushure mokunge mhinduro yacho yapera, kucheneswa uye kupatsanurwa kunoitwa nekristalllization kana distillation kuwana 2-fluoro-4-bromobenzyl bromide nekuchena kwakanyanya.
Zvekuchengetedza
- 2-Fluoro-4-bromobenzyl bromide is volatile organic compound uye mhute dzayo dzinofanira kudzivirirwa nekufema.
- Pfeka zvidziviriro zvekuzvidzivirira nazvo zvakaita semagirazi ekudzivirira, magirovhosi uye majasi erabhoritari panguva yekubata nekubata.
- Paunenge uchichengeta uye uchishandisa, dzivisa kusangana neoxidants, yakasimba asidhi, yakasimba alkali uye zvimwe zvinhu kudzivirira kuita zvine njodzi.
- Kana uchiichengeta uye uchiirasa, mitemo yakakodzera, mirau uye mirairo yekuchengetedza inofanirwa kucherechedzwa.
