Fa'aoga O le Nitrobenzene o se mea fa'ale-aganu'u taua tele. O le Nitrobenzene na fa'auluina i le sulfur trioxide e maua ai le m-nitrobenzene sulfonic acid. E mafai ona fa'aaogaina e fai ma vali va'ava'ai, fa'ama'i fa'ama'i ma masima fa'ama'i. Nitrobenzene sa sulfonated i le chlorosulfonic acid e maua ai le m-nitrobenzenesulfonyl chloride, lea na faʻaaogaina e fai ma vaeluaga o le vali, vailaʻau ma isi. Nitrobenzene ua chlorinated i M-nitrochlorobenzene, lea e masani ona faaaoga i le gaosiga o vali ma vailaau faalafua. A maeʻa le faʻaititia, e mafai ona maua le M-chloroaniline. Fa'aaogaina e pei o se vali moli GC, o se vaila'au fa'ama'i, vailaau fa'ala'au fa'ato'aga, fa'amalama pa'epa'e fluorescent, vaila'au vaila'au fa'alaulaula. Nitrobenzene re-nitration e mafai ona m-dinitrobenzene, e ala i le faaitiitia e mafai ona m-phenylenediamine, faʻaaogaina e pei o le vali, epoxy resin curing agent, petroleum additives, Cement accelerator, M-dinitrobenzene e pei o le sodium sulfide mo se vaega foi mataupu faavae i le M-nitroaniline. Mo le lanu moli fa'avae R, o se vaeluagalemu o vali azo ma pigments fa'aola.

Folasaga

Nitrobenzene) o se vailaʻau faʻapitoa e mafai ona avea ma se tioata paʻepaʻe paʻepaʻe poʻo se vai samasama ma se manogi faʻapitoa. O lo'o ta'ua i lalo se fa'amatalaga i nisi o mea totino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le nitrobenzene:

 

Tulaga lelei:

O le Nitrobenzene e le mafai ona solu i le vai ae e mafai ona solu i solu faʻaletino e pei ole ava malosi ma ethers.

E mafai ona maua e ala i le faʻamaʻiina o le benzene, lea e gaosia e ala i le faʻaogaina o le benzene ma le nitric acid faʻapitoa.

O le Nitrobenzene o se faʻamautu mautu, ae e paʻu foi ma e maualuga lona mu.

 

Fa'aaogā:

O le Nitrobenzene o se vailaʻau taua tele ma e faʻaaogaina lautele i le faʻaogaina o meaola.

E mafai foi ona faʻaaogaina le Nitrobenzene e fai ma faʻaopoopoga i solvents, vali ma ufiufi.

 

Metotia:

O le auala sauniuni o le nitrobenzene e masani lava ona maua mai i le tali faʻamaʻi o le benzene. I totonu o le falesuesue, e mafai ona faʻafefiloi le benzene ma le nitric acid concentrated ma le concentrated sulfuric acid, faʻafefe i le maualalo o le vevela, ona fufulu lea i le vai malulu e maua ai le nitrobenzene.

 

Fa'amatalaga Saogalemu:

O le Nitrobenzene ose vaila'au oona, ma o le fa'aalia po'o le manavaina o lona ausa e mafai ona afaina ai le tino.

Ose mea e mu ma pa ma e tatau ona aloese mai le fa'afeso'ota'i ma puna fa'amumu.

O mea e puipui ai le tagata lava ia e pei o totigilima ma mata tioata e tatau ona ofuina pe a tagofia le nitrobenzene, ma e tatau ona tausia lelei se siosiomaga faʻaoga lelei.

Pe a tula'i mai se liki po'o se fa'alavelave, e tatau ona vave faia ni faiga talafeagai e fa'amama ma lafoa'i. Ia usita'ia tulafono ma tulafono fa'atatau e lafoa'i lelei ai otaota ua gaosia.
