Okwu mmalite

3,4-Dichloronitrobenzene bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, usoro nkwadebe na ozi nchekwa ya:

 

Ogo:

- 3,4-Dichloronitrobenzene bụ kristal na-enweghị agba ma ọ bụ kristal na-acha odo odo na-esi ísì ụtọ.

- Na-adịghị ike na mmiri na ụlọ okpomọkụ, ma soluble na ọtụtụ organic solvents.

 

Jiri:

Enwere ike iji 3,4-Dichloronitrobenzene mee ihe dị ka reagent kemịkalụ dị ka mkpụrụ maka mmeghachi omume nitrosylation.

- A pụkwara iji ya mee ihe dị ka ihe mmalite maka njikọ nke ogige ndị ọzọ, dị ka glyphosate, ahịhịa ahịhịa.

 

Usoro:

- 3,4-Dichloronitrobenzene na-akwadokarị site na chlorination nke nitrobenzene. Usoro nkwadebe akọwapụtara nwere ike iji ngwakọta nke sodium nitrite na nitric acid, wee meghachi omume na benzene n'okpuru ọnọdụ mmeghachi omume kwesịrị ekwesị. Mgbe mmeghachi omume ahụ gasịrị, a na-asachapụ ngwaahịa ezubere iche site na crystallization na usoro ndị ọzọ.

 

Ozi nchekwa:

- 3,4-Dichloronitrobenzene na-egbu egbu ma nwee ike imerụ ahụ ike mmadụ. Mkpughe, iku ume, ma ọ bụ iri ihe a nwere ike ime ka anya, iku ume na mgbakasị anụ ahụ.
