2-Fluoro-4-bromobenzaldehyde ke motsoako oa tlhaho. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea komporo ena:
Boleng:
- Ponahalo: 2-Fluoro-4-bromobenzaldehyde ha e na 'mala ho isa ho bosehla bo tiileng.
- Sollubility: E qhibiliha ka har'a metsoako e meng ea polar joalo ka ethanol le methylene chloride.
- Botsitso: 2-Fluoro-4-bromobenzaldehyde ke motsoako o sa tsitsang o amehang habonolo ke khanya le mocheso 'me o ka senyeha habonolo ka ho futhumatsa.
Sebelisa:
- E ka boela ea sebelisoa libakeng tse kang dae synthesis, catalysts, le lisebelisoa tsa optical.
Mokhoa:
2-Fluoro-4-bromobenzaldehyde e ka etsoa ka mekhoa e fapaneng, joalo ka:
2-bromo-4-fluorobenzyl joala e ka arajoa ka tharollo ea acidic, tharollo ea karabelo e ka fokotsoa 'me ea silafatsoa ho fumana sehlahisoa se hloekisitsoeng.
E ka boela ea fumanoa ka oxidizing 4-fluorostyrene boteng ba ethyl bromide.
Lintlha tsa Tšireletseho:
2-Fluoro-4-bromobenzaldehyde ke motsoako oa tlhaho o hlokang mekhoa e nepahetseng ea polokeho le mehato e lokelang ho lateloa:
- 2-Fluoro-4-bromobenzaldehyde e ea tena 'me e ka baka tšenyo ea mahlo, letlalo le tsela ea ho hema. Ha o sebetsa, hoa hlokahala ho roala lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka likhalase, liatlana le limaske.
- Qoba ho hema mouoane ho tsoa likhase kapa litharollong tsa bona. Balebeli ba lokela ho sebetsoa kapa ba sebelisoe sebakeng se nang le moea o motle.
- Qoba ho pepesehela khanya ea letsatsi kapa mocheso. E lokela ho bolokoa sebakeng se phodileng, se omileng ho qoba ho kopana le li-oxidants.
- Se ke oa kopanya 2-fluoro-4-bromobenzaldehyde le li-oxidizing agents tse matla 'me u se ke ua tšelela metsing kapa libakeng tse ling.
Pele u sebelisa 2-fluoro-4-bromobenzaldehyde, etsa bonnete ba hore u bala le ho utloisisa maqephe a amehang a polokeho le libuka tsa ts'ebetso, 'me u latele mekhoa e nepahetseng ea ho sebetsana le ho lahla.
