Selelekela

2,4-Dibromobenzoic acid ke motsoako oa manyolo. Ke kristale e tšoeu kapa phofo ea crystalline. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 2,4-dibromobenzoic acid:

 

Boleng:

- Ponahalo: Likristale tse tšoeu kapa phofo ea kristale.

- Sollubility: Ha e qhibilihe ka har'a lihlapolli tsa tlhaho tse kang ethanol, ether le chloroform, e sa qhibiliheng metsing.

 

Sebelisa:

- E ka boela ea sebelisoa e le motsoako oa antioxidant le rabara, har'a lintho tse ling.

 

Mokhoa:

- Mokhoa oa ho lokisa oa 2,4-dibromobenzoic acid o fumanoa haholo-holo ka karabelo ea bromination ea benzoic acid. Boemong bo ikhethileng, asiti ea benzoic e qala ka ho kopana le bromine boteng ba asiti ea asiti ho etsa asiti ea bromobenzoic. Joale, asiti ea bromobenzoic e entsoe ka hydrolyzed ho fana ka 2,4-dibromobenzoic acid.

 

Lintlha tsa Tšireletseho:

- 2,4-Dibromobenzoic acid e batla e tsitsitse mocheso oa kamore, empa e ka bola ka mocheso o phahameng kapa malakabe a bulehileng ho hlahisa likhase tse chefo.

- Hoa teneha 'me ho ka baka ho teneha le ho se thabise ha u kopana le letlalo, mahlo, le tsela ea ho hema.

- Mehato e nepahetseng ea ts'ireletso ea botho joalo ka liatlana tse sireletsang, ts'ireletso ea mahlo, le lisebelisoa tsa ts'ireletso ea phefumoloho li lokela ho nkuoa ha ho sebelisoa, ho boloka le ho tšoara.

- E lokela ho bolokoa hole le mehloli ea mollo le li-oxidizing, ebe e bolokoa sebakeng se phodileng, se nang le moea o pholileng.
