Njirimara ngwaahịa:
1.Benzene bụ otu n'ime ihe ndị kasị mkpa isi organic akụrụngwa na onye nnọchiteanya nke aromatic hydrocarbons. Ọ nwere ihe mgbanaka nwere akụkụ isii kwụsiri ike.
2.The isi mmeghachi omume kemịkalụ bụ mgbakwunye, nnọchi na mmeghachi omume mmeghe. N'okpuru ọrụ nke sulfuric acid na nitric acid, ọ dị mfe ịmepụta nitrobenzene site na mmeghachi omume nnọchi. Mee ya na sulfuric acid gbadoro ụkwụ ma ọ bụ fuming sulfuric acid iji mepụta benzenesulfonic acid. Site na halides metal dị ka ferric chloride dị ka ihe na-akpali akpali, mmeghachi omume halogenation na-eme na obere okpomọkụ iji mepụta benzene halogenated. Na aluminom trichloride dị ka ihe na-akpata, mmeghachi omume alkylation na olefins na halogenated hydrocarbons iji mepụta alkylbenzene; mmeghachi omume acylation na acid anhydride na acyl chloride iji mepụta acylbenzene. Na ọnụnọ nke vanadium oxide catalyst, benzene na-eme ka ikuku oxygen ma ọ bụ ikuku na-emepụta maleic anhydride. Benzene dị ọkụ ruo 700 Celsius C na-agbawa, na-emepụta carbon, hydrogen na obere methane na ethylene na ihe ndị ọzọ. N'iji platinum na nickel eme ihe dị ka ihe na-emepụta ihe, a na-eme mmeghachi omume hydrogenation iji mepụta cyclohexane. Na zinc chloride dị ka ihe na-akpata, mmeghachi omume chloromethylation na formaldehyde na hydrogen chloride iji mepụta benzyl chloride. Ma mgbanaka benzene kwụsiri ike, dịka ọmụmaatụ, na nitric acid, potassium permanganate, dichromate na oxidants ndị ọzọ anaghị eme.
3.It nwere elu refractive onwunwe na ike aromatic ekpomeekpo, flammable na egbu egbu. Na-atụgharị ya na ethanol, ether, acetone, carbon tetrachloride, carbon disulfide na acetic acid, soluble ntakịrị na mmiri. Ọla anaghị emebi emebi na ọla, mana ọkwa dị ala nke benzene nwere sọlfọ adịghị na ọla kọpa na ụfọdụ ọla nwere mmetụta na-emebi emebi doro anya. Liquid benzene nwere mmetụta na-emebi emebi, akpụkpọ ahụ na nsị nwere ike ịmịnye ya, yabụ zere ịkpọtụrụ akpụkpọ ahụ.
4.Vapour na ikuku na-emepụta ngwakọta ihe mgbawa, njedebe mgbawa nke 1.5% -8.0% (olu).
5.Stability: Stable
6. Ihe ndị amachibidoro:Sacids, halogen, oxidants
7. Polymerisation ihe egwu:Ndị na-abụghị polymerisation
Ngwa ngwaahịa:
Ngwa ngwa kemịkalụ bụ isi, nke ejiri dị ka ihe mgbaze na ihe nrụpụta benzene sịntetik, ngwa nri, akwa, plastik, ọgwụ, mgbawa, rọba, wdg.

1.Chekwaa n'ụlọ nkwakọba ihe dị jụụ, ikuku.
2.Chep n'ebe ọkụ na isi iyi ọkụ.
3.The nchekwa okpomọkụ ekwesịghị gafere 37 ° C.
4.Na-edebe akpa ahụ akara.
5.A ga-echekwa ya iche site na ndị na-emepụta ihe na-emepụta ihe, ọ dịghịkwa mgbe a ga-agwakọta ya.
6.Jiri ihe mgbawa na-agbawa ọkụ na akụrụngwa ikuku.
7.Machibido iji ngwá ọrụ na-arụ ọrụ na ngwá ọrụ ndị dị mfe ịmepụta ọkụ ọkụ.
8.Ebe nchekwa ahụ kwesịrị ịkwado ya na ngwa ngwa ọgwụgwọ mberede na-agbapụta na ihe mkpuchi kwesịrị ekwesị.
