Ko te nitration o te benzene he tukanga tūāpapa i roto i te hanga matū nui, e huri ana i te benzene me te waikawa whakauru ki te nitrobenzene, he takawaenga matū pai matua. Ko te whai huatanga whānui o te nitrobenzene e kapi ana i te hanga rongoā, tae, pahūtanga pēnei i te TNT, me ngā matū matū matatau. Ko te hiranga ahumahi o te tukanga e mau ana ehara i te mea ko te uara ōhanga o ngā tono nitrobenzene anake engari ko te kaha hoki o te whakahaere i ngā tawhā whakahaere.
He Tirohanga Whānui mō te Tukanga Nitration Benzene Ahumahi
Ko te nitration ahumahi o te benzene he taahiraa taketake i roto i te whakaputa nitrobenzene, he matū mua i roto i ngā takawaenga matū pai pēnei i te hanga aniline. I tōna pūtake, ka whakamahia e tēnei whakawhiti te whakakapinga kakara hiko-aroha, ka hurihia te benzene hei nitrobenzene mā te tauhohenga ki te ranunga nitrating—ko te waikawa hauota kukū me te waikawa whanariki te tikanga. Mā te waikawa whakaranu ka āwhina i te hanganga o te nitronium ion (NO₂⁺), te electrophile matua, mā te tauhohenga:
2 H₂SO₄ + HNO₃ → NO₂⁺ + H₃O⁺ + 2 HSO₄⁻
Ka whakaekea e te katote nitronium te mowhiti benzene, ka puta he nitrobenzene me te tuku wera nā te āhua werawera o te tauhohenga. He mea nui te whakahaere pakari i te pāmahana, te kukū waikawa, me ngā tere rere o te matū tauhohenga; ka taea e ngā rerekētanga wera nui, kukū rānei te whakaputa i ngā hua taha kāore e hiahiatia me te kore pumau o te tukanga, ka waiho kia tino hiahiatia ngā tawhā whakahaere kua whakatikatikaina mō te hanganga nitrobenzene tino pai me te karo i ngā tauhohenga taha kino.

Ko te kaha wera nui o te tauhohenga me whakauru ngā whakawhiti wera, ngā koti whakamatao rānei ki roto i ngā oko tauhohenga. Me tu atu ngā rauemi hanga tauhohenga ki te pānga tonu ki ngā waikawa tino waikura me te waikura. He mea noa ngā tauhohenga maitai kua whakakikoruatia ki te karāhe me te fluoropolymer, engari ka taea e te tantalum me ngā koranu ātete-waikura te whakarato i te roa o te ora i roto i ngā wāhi tino nui, inā koa me te whakaurunga o ngā tuku pēhanga diaphragm tantalum mō te ine pēhanga tika, pumau. Ko te koretake o te matū o te tantalum i raro i ngā āhuatanga waikawa whakauru ka whakaiti i te tiaki me te wā kore mahi.
He mea nui te ine i te pēhanga whai hua i roto i ngā tauhohenga hauota. Ko te pupuri i te pēhanga i roto i ngā rohe haumaru, kua hoahoatia, ka whakarite i te hanganga pai, ka whakaiti i ngā mōrearea e pā ana ki te whakawhāiti i te whāngai, ā, ka taea te whakahaere porowhita kati mō ngā pūnaha aunoa. Mā te aroturuki pēhanga wā-tūturu, mā te whakamahi i ngā tuku tuku matatau kua hangaia mō ngā taiao kaha, ka tautoko i te haumaru me te arotau tukanga. Ka whakamahia e ngā tauhohenga hou ngā tuku tuku pēhanga ā-roto kua whakanohohia ki ngā wāhi horoi-whaiaro me ngā huringa horoi auau hei ārai i ngā aukati mai i ngā totoka e maturuturu ana, i ngā hau e whanake ana rānei e kitea ana i roto i te ranunga hau-wai-totoka e toru-wāhanga e kitea ana i te wā e mahi tonu ana.

Mā tēnei whakahaere pēhanga tonu ka taea e ngā kaiwhakahaere te karo i ngā pikinga ohorere, morearea o te pēhanga tauhohenga me te pupuri tonu i te haere tonu o te tukanga.
Ko ngā whanaketanga hou o te whakakorikori kanorau—ina koa ko ngā whakakorikori waikawa totoka e pai ana ki te taiao—ka nui ake ngā hua me te whakaiti i te whakamahinga waikawa whanariki. Ka whakapai ake tēnei auahatanga i te pumau o te huarahi whakaputa nitrobenzene me te whakaiti i te mōrearea waikura e pā ana ki te whakamahinga nui o ngā waikawa kaha. Mā te whakamahi i ngā nanocatalysts kua whakaritea, i ngā rauemi waikura hiato rānei, ka tutuki i ngā kaihanga te whakaputanga ira nitronium whai hua i roto i ngā tauhohenga wai-wāhanga, ka whakangawari i te mahi tauhohenga, ka whakaiti i te pānga ki te taiao, me te whakahaere i te whakahaere pēhanga ngāwari ake.
Ko te whiriwhiri rauemi mō ngā roto o te tauhohenga me ngā taputapu he mea nui tonu, nā te mea he nui ngā tūmomo waikura e pā ana ki ngā waikawa whakauru. Ko ngā tuku pēhanga tantalum diaphragm he mea noa i roto i ngā whakaurunga hou mō tō rātou ātete ki te whakaeke matū, te whakaiti i ngā whakakapinga utu nui, me te tuku i ngā wā mahi roa me te kore e aukati i te tukanga.
I te nuinga o te wā, ka whakamahia e te nitration benzene ahumahi te matū tika, te hangarau tauhohenga whakahaere, ngā taputapu motuhake, me ngā rauemi ātete-waikura matatau hei whakaputa i te hanga nitrobenzene haumaru, tauine. Ko ia whanaketanga i roto i te hoahoa tauhohenga, te hangarau whakakorikori, te whakahaere pēhanga wā-tūturu rānei e tautoko tika ana i te whai huatanga me te pono e hiahiatia ana i roto i te hanga takawaenga matū pai.
