Selelekela
2,5-Difluorobenzaldehyde. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:
Boleng:
2,5-Difluorobenzaldehyde ke mokelikeli o mosehla o se nang 'mala ho isa ho o khanyang o nang le lets'oao le matla la ho cha, monko o hlabang mochesong oa kamore. Ha e qhibilihe ka metsing empa e ka qhibiliha ka har'a metsoako ea tlhaho e kang ethanol, toluene, joalo-joalo.
Sebelisa:
2,5-Difluorobenzaldehyde e na le mefuta e mengata ea lisebelisoa ho organic synthesis. E ka sebelisoa e le selelekela sa motsoako oa metsoako e nkhang hamonate, li-derivatives tsa paraphthalenedione, le limolek'hule tsa bioactive. E ka boela ea sebelisoa ha ho etsoa li-complexes tsa organometallic, liaparo tse phahameng tsa ts'ebetso le lidae.
Mokhoa:
2,5-difluorobenzaldehyde e ka lokisoa ke karabelo ea benzaldehyde le hydrogen fluoride. Hangata karabelo ena e etsoa tlas'a maemo a asiti 'me e ka finyelloa ka ho sebelisa hydrofluoric acid e le mohloli oa hydrogen fluoride.
Lintlha tsa Tšireletseho:
Litlhokomelo tse hlokahalang li lokela ho nkoa ha ho sebelisoa 2,5-difluorobenzaldehyde. E na le lintho tse hlabang letlalong, mahlo le tsela ea ho hema. Likhalase tse sireletsang lik'hemik'hale, liatlana le liaparo tse sireletsang li lokela ho apesoa 'me ho kopana ka ho toba ho lokela ho qojoa. Haeba e kena mahlong kapa letlalong la hao, e hlatsoe hang-hang ka metsi a mangata 'me u batle ngaka kapele kamoo ho ka khonehang. Nakong ea ts'ebetso, e lokela ho behoa hole le mehloli ea mollo le ho qoba mosi le mouoane ho qoba mollo le ho phatloha.
Ena ke kenyelletso e khutšoanyane ea thepa, tšebeliso, mekhoa ea ho lokisa le tlhahisoleseding ea polokeho ea 2,5-difluorobenzaldehyde. Haeba ho hlokahala, etsa bonnete ba hore o utloisisa le ho latela melao le tataiso e nepahetseng ea polokeho ea laboratori pele o sebetsa kapa o sebelisoa.
