wairewa i roto i te waiwaro, te etera me te benzene, he paku whakarewa ki te wai.
Ko te hua Pure he wai hinuhinu kore tae ki te kowhai kowhai. Wairewa ki te waiwaro, ether me te benzene, wairewa-wai.
Whakamahi Ko te Nitrobenzene he takawaenga pararopi nui. Ko te Nitrobenzene i sulfonated ki te sulfur trioxide ki te tiki m-nitrobenzene sulfonic acid. Ka taea te whakamahi hei waikano takawaenga, he waikano ngawari me te tote anti-waikano. Ko te Nitrobenzene i whakangao ki te waikawa chlorosulfonic kia whiwhi ai i te m-nitrobenzenesulfonyl chloride, i whakamahia hei takawaenga o te waikano, rongoa me etahi atu. Ko te Nitrobenzene he maota ki te M-nitrochlorobenzene, e whakamahia nuitia ana ki te hanga waikano me te pesticides. I muri i te whakahekenga, ka taea te tiki M-chloroaniline. Ka whakamahia hei GC karaka karaka, he rongoa, pesticide, he maataki whakamaarama korikori, he takawaenga poaka waro. Ka taea e Nitrobenzene re-nitration te m-dinitrobenzene, ma te whakaheke ka taea te m-phenylenediamine, whakamahia hei takawaenga waikano, epoxy kapia whakaora kaihoko, petroleum additives, Cement accelerator, M-dinitrobenzene pērā i te konutai sulfide mo tetahi waahanga kaupapa mo te M-nitroaniline. Mo te waikano karaka turanga R, he takawaenga o nga waikano azo me nga poaka waro.

Kupu Whakataki

Ko te Nitrobenzene) he puhui pararopi ka taea te toka ma te kirikiriata ma, he wai kowhai me te kakara motuhake. E whai ake nei he kupu whakataki mo etahi o nga taonga, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te nitrobenzene:

 

Kounga:

Ko te Nitrobenzene e kore e rewa i roto i te wai engari ka whakarewahia i roto i nga whakarewa pararopi penei i te waipiro me te etera.

Ka taea te tiki mai ma te whakaene i te benzene, ka puta mai ma te tauhohe i te benzene me te waikawa nitric.

He pūhui pūmau te Nitrobenzene, engari he pahū, ā, he muramura teitei.

 

Whakamahia:

Ko te Nitrobenzene he rawa matū nui, he nui te whakamahi i roto i te whakahiato waro.

Ka taea hoki te whakamahi i te Nitrobenzene hei taapiri i roto i nga whakarewa, peita me nga paninga.

 

Tikanga:

Ko te tikanga whakarite o te nitrobenzene te nuinga ka whiwhi i te tauhohenga nitrification o te benzene. I roto i te taiwhanga, ka taea te whakauru i te benzene ki te waikawa nitric concentrated me te waikawa sulfuric concentrated, ka whakaohokia ki te iti o te mahana, katahi ka horoia ki te wai matao kia whiwhi nitrobenzene.

 

Mōhiohio Haumaru:

Ko te Nitrobenzene he puhui paitini, a, ko te rongonga ki te whakamohiotanga ranei o tana kohu ka kino te tinana.

He pūhui muramura, pahū, ā, me karo i te whakapā atu ki ngā mātāpuna whakakā.

Ko nga taputapu whakamarumaru whaiaro penei i nga karapu whakamarumaru me nga karaehe me mau i te wa e whakahaere ana i te nitrobenzene, me te pupuri i te taiao whakahaere pai.

Mena he turuturu, he aitua ranei, me tere tonu te mahi ki te horoi me te tuku atu. Kia mau ki nga ture me nga ture e pa ana ki te tuku tika i nga para ka mahia.
