Okwu mmalite

Nitrobenzene) bụ ngwakọta organic nke nwere ike ịbụ kristal ọcha siri ike ma ọ bụ mmiri mmiri na-acha odo odo nwere ísì pụrụ iche. Ihe na-esonụ bụ mmalite nke ụfọdụ njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke nitrobenzene:

 

Ogo:

Nitrobenzene bụ ihe a na-adịghị ahụkebe na mmiri mana ọ na-agbaze na ihe mgbaze organic dị ka alcohols na ethers.

Enwere ike nweta ya site na nitrating benzene, nke a na-emepụta site na iji nitric acid meghachi omume na benzene.

Nitrobenzene bụ ogige kwụsiri ike, mana ọ na-agbawakwa ma nwee nnukwu ọkụ.

 

Jiri:

Nitrobenzene bụ ihe dị mkpa kemịkalụ akụrụngwa na-eji ọtụtụ ebe na organic njikọ.

Nitrobenzene nwekwara ike iji dị ka ihe mgbakwunye na ihe mgbaze, agba na mkpuchi.

 

Usoro:

Usoro nkwadebe nke nitrobenzene na-enwetakarị site na mmeghachi omume nitrification nke benzene. N'ime ụlọ nyocha, enwere ike ịgwakọta benzene na nitric acid na-etinye uche na sulfuric acid, kpalie ya na obere okpomọkụ, wee kpochaa ya na mmiri oyi iji nweta nitrobenzene.

 

Ozi nchekwa:

Nitrobenzene bụ ihe na-egbu egbu, na ikpughe ma ọ bụ ikuku ume nke vepo ya nwere ike imebi ahụ.

Ọ bụ ihe na-ere ọkụ na ihe mgbawa ma kwesịrị izere kọntaktị na isi mmalite mgbanye.

Ekwesịrị iyi akụrụngwa nchedo onwe onye dị ka uwe mkpuchi na enyo enyo mgbe ị na-eji nitrobenzene, yana ebe ikuku na-arụ ọrụ nke ọma kwesịrị idowe ya.

Ọ bụrụ na ihipu ma ọ bụ ihe mberede, ekwesịrị ịme ihe kwesịrị ekwesị ozugbo iji hichaa ma tụfuo ya. Soro iwu na ụkpụrụ dị mkpa iji kpofuo ihe mkpofu emepụtara nke ọma.
