Nitrobenzene) ke motsoako oa lintho tse phelang o ka bang 'mala o mosoeu oa kristale kapa mokelikeli o mosehla o nang le monko o khethehileng. Se latelang ke selelekela sa tse ling tsa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea nitrobenzene:

 

Boleng:

Nitrobenzene ha e qhibilihe ka metsing empa e qhibiliha ka har'a metsoako ea tlhaho e kang joala le ethers.

E ka fumanoa ka ho etsa benzene ea nitrate, e hlahisoang ke benzene e nang le asiti ea nitric.

Nitrobenzene ke motsoako o tsitsitseng, empa o boetse oa phatloha 'me o na le ho chesa haholo.

 

Sebelisa:

Nitrobenzene ke sehlahisoa sa bohlokoa sa lik'hemik'hale 'me se sebelisoa haholo ho organic synthesis.

Nitrobenzene e ka boela ea sebelisoa e le motsoako oa lihlapolli, lipente le litlolo.

 

Mokhoa:

Mokhoa oa ho lokisa oa nitrobenzene o fumanoa haholo-holo ka karabelo ea nitrification ea benzene. Ka laboratoring, benzene e ka tsoakoa le acid e concentrated nitric le concentrated sulfuric acid, e tsosoa ka mocheso o tlase, ebe e hlatsuoa ka metsi a batang ho fumana nitrobenzene.

 

Lintlha tsa Tšireletseho:

Nitrobenzene ke motsoako o chefo, 'me ho pepesetsoa kapa ho hema mouoane oa oona ho ka baka tšenyo 'meleng.

Ke motsoako o tukang le o phatlohang 'me o lokela ho qoba ho kopana le mehloli ea mollo.
