Selelekela
2-Fluoro-4-bromobenzyl bromide ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
- Ponahalo: 2-Fluoro-4-bromobenzyl bromide ke mokelikeli o se nang 'mala ho isa ho o mosehla o mosehla.
- Sollubility: E qhibiliha ka har'a metsoako ea tlhaho e kang joala le ethers, empa ha e qhibilihe ka metsing.
Sebelisa:
- 2-Fluoro-4-bromobenzyl bromide e atisa ho sebelisoa e le setsi sa bohlokoa sa lipakeng tsa tlhaho ea tlhaho.
- Motsoako ona o ka sebelisoa hape e le lisebelisoa tse tala bakeng sa li-catalysts le li-surfactants.
Mokhoa:
Mokhoa oa ho lokisa 2-fluoro-4-bromobenzyl bromide ke o latelang:
- Karabelo ea joala ea 2-bromobenzyl e nang le 2,4-difluorobenzoic acid, e hlahisoang ke alkali, ka mocheso o loketseng le maemo a nako.
- Ka mor'a hore karabelo e phethoe, ho hloekisa le ho arohana ho etsoa ka crystallization kapa distillation ho fumana 2-fluoro-4-bromobenzyl bromide e nang le bohloeki bo phahameng.
Lintlha tsa Tšireletseho:
- 2-Fluoro-4-bromobenzyl bromide ke motsoako oa lintho tse phelang o fetohang 'me mouoane oa oona o lokela ho qojoa ka ho hema.
- Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka likhalase tsa ts'ireletso, liatlana le lijase tsa lab nakong ea ho ts'oaroa le ho ts'oaroa.
- Ha u boloka le ho sebelisa, qoba ho kopana le li-oxidants, li-acids tse matla, li-alkali tse matla le lintho tse ling ho qoba liketso tse kotsi.
- Ha o e boloka le ho e lahla, melao e amehang, melawana le melawana ya polokeho di lokela ho hlokomelwa.
