Tlhaho:

-Ponahalo: 2,6-dinitrobenzaldehyde e le likristale tse mosehla.

-Solubility: E batla e sa qhibilihe ka metsing, empa e qhibiliha ka har'a metsoako e mengata ea tlhaho e kang ethanol, dichloromethane, joalo-joalo.

- Sebaka sa ho qhibiliha: Sebaka sa eona sa ho qhibiliha se boemong ba likhato tse 145-147 tsa Celsius.

-Monko: E na le monko o matla o hlabang.

 

Sebelisa:

-Chemical reagent: 2,6-dinitrobenzaldehyde e atisa ho sebelisoa e le lik'hemik'hale tsa lik'hemik'hale ho lokisetsa metsoako e meng.

-Synthesis intermediate: Hape ke karolo e bohareng ea motsoako oa tlhaho. Ka mohlala, e ka sebelisoa ha ho etsoa dae, chefo e bolaeang likokoanyana, meriana le tse ling tse joalo.

 

Mokhoa oa ho itokisa:

-Mokhoa oa ho itokisa oa 2,6-dinitrobenzaldehyde hangata o finyelloa ke karabelo ea nitrobenzaldehyde. Ntlha ea pele, karabelo ea benzaldehyde le concentrated nitric acid, 'me ka mor'a maemo a loketseng a acidic ea phekolo, u ka fumana 2,6-dinitrobenzaldehyde.

 

Lintlha tsa Tšireletseho:

- 2,6-dinitrobenzaldehyde ke ntho e chefo 'me e lokela ho tšoaroa ka hloko. Qoba ho kopana ka ho toba le letlalo, mahlo le tsela ea ho hema.

-Apara lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liatlana, likhalase le liaparo tsa lab ha u sebelisa kapa u tšoara motsoako ona ho thibela ho kopana le ho hema.

-Litšila li lokela ho lahloa ho latela mekhoa e behiloeng ho qoba tšilafalo ea tikoloho.
