Selelekela

Ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H3BrFN. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:

 

Tlhaho:

-Ponahalo: E tiileng ka kristale e se nang 'mala.

- Sebaka sa ho qhibiliha: hoo e ka bang 59-61°C.

Sebaka se belang: hoo e ka bang 132-133 ℃.

- Monko o monate: Ha ho na data e tšepahalang.

-Solubility: Ho qhibiliha ka har'a metsoako ea lintho tse phelang tse kang ether, dimethylformamide le benzene, e sa qhibiliheng metsing.

 

Sebelisa:

-ke organic synthesis intermediate e ka sebelisoang ho kopanya metsoako e kang lithethefatsi, chefo e bolaeang likokoanyana le dae.

-E ka sebelisoa e le reagent bakeng sa ho hlahisa halogen ka metsoako e nkhang hamonate ho organic synthesis.

 

Mokhoa oa ho itokisa:

-fluorobenzonitrile e ka lokisoa ka ho eketsa cuprous bromide (CuBr) ho 4-fluorobenzonitrile (C7H4FN).

 

Lintlha tsa Tšireletseho:

-E ka 'na ea halefisa le ho senya,' me ho kopana le letlalo le mahlo ho ka baka ho teneha.

-Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka likhalase, liatlana le lijase tsa lab nakong ea ts'ebetso.

-Ha u sebelisa le ho boloka, hoa hlokahala ho lumellana le mekhoa e sireletsehileng ea ts'ebetso le ho boloka hantle ka har'a setshelo se tiisitsoeng, hole le li-ignition le li-oxidizing agents.

-Haeba o hema kapa o kene, batla thuso ea bongaka hang-hang. Haeba ho kopana ho etsahala, hang-hang hlatsoa sebaka se amehileng ka metsi a mangata 'me u batle thuso ea bongaka.
