2,4-Dinitroaniline ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

 

Boleng:

- 2,4-Dinitroaniline ke kristale e mosehla e ke keng ea qhibiliha ka metsing.

- E na le sebaka se phahameng sa ho tima le ho phatloha, 'me e hlalosoa e le seqhomane.

- E ka fokotsoa ho metsoako ea amine ka metheo e matla le hydroxides.

 

Sebelisa:

- 2,4-Dinitroaniline e sebelisoa haholo indastering ea lik'hemik'hale e le thepa e tala bakeng sa liqhomane le liqhomane.

- E ka boela ea sebelisoa ha ho etsoa dae le li-pigments, hammoho le karolo ea bohlokoa ea bohareng.

 

Mokhoa:

- Tokisetso ea 2,4-dinitroaniline hangata e etsoa ke nitrification. p-nitroaniline e sebetsana le acid e ngata ea nitric ho theha 2,4-dinitronitroaniline, ebe e fokotsa motsoako ka acid e matla ho fumana 2,4-dinitroaniline.

 

Lintlha tsa Tšireletseho:

- 2,4-Dinitroaniline ke k'hemik'hale e phatlohang haholo 'me e lokela ho behoa hole le malakabe a bulehileng le mehloli ea mocheso.

- Kotsi ea likhohlano, tšusumetso, litlhase le ho tsoa ha motlakase li hloka ho laoloa ka thata nakong ea ho ts'oaroa, ho boloka le ho tsamaisa.

- Apara lisebelisoa tse loketseng tsa ho itšireletsa tse kang likhalase tsa tšireletso le liatlana tse sireletsang ha u sebelisoa. Haeba u ka nooa, batla thuso ea bongaka hang-hang.
