3,4-Dibromobenzoic acid ke motsoako oa manyolo. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:

Boleng:

3,4-Dibromobenzoic acid ke kristale e se nang mebala e nang le monko o khethehileng. E tsitsitse ho khanya le moeeng, empa e ka bola ka mocheso o phahameng.

Sebelisa:

3,4-Dibromobenzoic acid e ka sebelisoa ka karabelo e fapaneng le li-reagents ho organic synthesis. E ka boela ea sebelisoa e le e 'ngoe ea lisebelisoa tsa organic light-emitting diode (OLEDs).

Mokhoa:

Ho lokisoa ha 3,4-dibromobenzoic acid ho ka fumanoa ka bromination ea tharollo ea bromobenzoic acid. Benzoic acid e qala ka ho qhibiliha ka har'a motsoako o loketseng ebe bromine e kenngoa butle-butle. Ka mor'a hore karabelo e phethoe, sehlahisoa se fumanoa ka ho hloekisa le crystallization.

Tlhahisoleseding ea polokeho: Ke ea sehlopha sa li-halides tse phelang 'me e na le kotsi e ka bang kotsi ea ho ba kotsi ho batho le tikolohong. Qoba ho kopana le letlalo le mahlo ka kotloloho, 'me u netefatse hore u sebetsa sebakeng sa laboratoring e nang le moea o motle. Mehato e loketseng ea tšireletso ea botho e kang liatlana, likhalase tsa tšireletso, le seaparo sa lab se lokela ho nkoa ha ho tšoaroa motsoako ona. Litšila li lokela ho lahloa ka nepo ho latela melao ea tikoloho ea lehae.
