2,4-Dichloropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 2,4-dichloropyridine:

 

Boleng:

- 2,4-Dichloropyridine ha e na 'mala ho likristale tse mosehla kapa maro.

- E na le monko o matla o hlabang.

- 2,4-Dichloropyridine e na le "solubility" e tlaase, e sa tsitsang ka metsing, le ho qhibiliha hantle ka har'a lihlahisoa tsa tlhaho.

 

Sebelisa:

- 2,4-Dichloropyridine e ka sebelisoa e le reagent ea bohlokoa le e thusang ho kopanya lintho tse phelang.

- 2,4-Dichloropyridine e boetse e sebelisoa ka tloaelo e le moemeli oa phekolo ea holim'a tšepe bakeng sa ho tlosoa ha lifilimi tsa oxide kapa bakeng sa ho senya.

 

Mokhoa:

- Mokhoa oa ho itokisa oa 2,4-dichloropyridine hangata o fumanoa ka karabelo ea 2,4-dichloropyran le nitrous acid.

- Mocheso o nepahetseng le nako ea ho arabela lia hlokahala nakong ea karabelo, hammoho le taolo tlas'a maemo a acidic.

 

Lintlha tsa Tšireletseho:

- 2,4-Dichloropyridine ke motsoako oa lintho tse phelang, 'me tlhokomelo e lokela ho nkoa ts'ebetsong e sireletsehileng nakong ea tšebeliso.

- Ho pepesetsoa 2,4-dichloropyridine ho ka baka ho teneha letlalong, mahlo le tsamaiso ea ho hema.

- Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka liatlana, likhalase le lisebelisoa tsa ho hema ha u sebelisa.

- Qoba ho ama 2,4-dichloropyridine letlalong le pepeneneng le ho boloka tikoloho ea mosebetsi e nang le moea o motle.

- Ha u lahla litšila tsa 2,4-dichloropyridine, melao ea tsamaiso ea litšila ea lehae e lokela ho hlokomeloa.
