Pure product ndi mafuta amadzimadzi opanda mtundu mpaka otumbululuka. Kusungunuka mu ethanol, ether ndi benzene, sungunuka m'madzi.
Gwiritsani ntchito	Nitrobenzene ndi gawo lofunikira lapakati pake. Nitrobenzene anali sulfonated ndi sulfure trioxide kupeza m-nitrobenzene sulfonic acid. Itha kugwiritsidwa ntchito ngati utoto wapakatikati, wofatsa oxidant ndi anti-dye mchere s. Nitrobenzene anali sulfonated ndi chlorosulfonic asidi kupeza m-nitrobenzenesulfonyl kolorayidi, amene ankagwiritsidwa ntchito ngati wapakatikati utoto, mankhwala ndi zina zotero. Nitrobenzene amapangidwa ndi chlorine ku M-nitrochlorobenzene, yomwe imagwiritsidwa ntchito kwambiri popanga utoto ndi mankhwala ophera tizilombo. Pambuyo pochepetsa, M-chloroaniline imatha kupezeka. Ntchito ngati utoto lalanje GC, ndi mankhwala, mankhwala, fulorosenti whitening wothandizira, organic pigment intermediates. Nitrobenzene re-nitration ikhoza kukhala m-dinitrobenzene, pochepetsa ikhoza kukhala m-phenylenediamine, yogwiritsidwa ntchito ngati zopangira utoto, epoxy resin curing agent, petroleum additives, Cement accelerator, M-dinitrobenzene monga sodium sulfide mbali inanso mfundo ya M-nitroaniline. Kwa utoto lalanje maziko R, ndi wapakatikati wa azo utoto ndi organic pigment.

Mawu Oyamba

Nitrobenzene) ndi mankhwala omwe amatha kukhala oyera a crystalline olimba kapena madzi achikasu okhala ndi fungo lapadera. Zotsatirazi ndikuyambitsa zina mwazinthu, ntchito, njira zokonzekera ndi chidziwitso chachitetezo cha nitrobenzene:

Ubwino:

Nitrobenzene sasungunuka m'madzi koma amasungunuka mu zosungunulira monga ma alcohols ndi ethers.

Itha kupezedwa ndi nitrating benzene, yomwe imapangidwa pochita benzene yokhala ndi nitric acid.

Nitrobenzene ndi chinthu chokhazikika, koma chimakhalanso chophulika ndipo chimakhala chotentha kwambiri.

Gwiritsani ntchito:

Nitrobenzene ndi mankhwala ofunikira ndipo amagwiritsidwa ntchito kwambiri popanga organic synthesis.

Nitrobenzene itha kugwiritsidwanso ntchito ngati chowonjezera mu zosungunulira, utoto ndi zokutira.

Njira:

Njira yokonzekera nitrobenzene imapezeka makamaka ndi nitrification reaction ya benzene. Mu labotale, benzene akhoza kusakaniza ndi chigawo cha nitric acid ndi sulfuric acid, yosonkhezera kutentha pang'ono, ndiyeno nkuchapitsidwa ndi madzi ozizira kuti mupeze nitrobenzene.

Zambiri Zachitetezo:

Nitrobenzene ndi poizoni, ndipo kukhudzana ndi kapena kupuma mpweya wake kungayambitse kuwonongeka kwa thupi.

Ndi chinthu choyaka komanso kuphulika ndipo sayenera kukhudzana ndi zoyatsira.

Zida zodzitetezera monga magolovesi ndi magalasi odzitetezera ziyenera kuvalidwa pogwira nitrobenzene, komanso malo opangira mpweya wabwino ayenera kusamalidwa.

Pakavunda kapena ngozi, njira zoyenera ziyenera kuchitidwa mwamsanga kuti ziyeretsedwe ndi kuzitaya. Tsatirani malamulo ndi malamulo oyenera kutaya zinyalala zomwe zapangidwa.
