Ko te P-nitroacetophenone he takawaenga nui i roto i te whakahiato waro, ka whakamahia hei rauemi mata mo te whakahiato o te chlortetracycline me te chloramphenicol i roto i te rongoa.Ko te tikanga tuku iho mo te hanga ahumahi o te p-nitroacetophenone ko te oxidation o te ethylbenzene.I tua atu i te hua matua p-nitroacetophenone, he hua-a-hua penei i te waikawa p-nitrobenzoic i roto i te punaha tauhohenga.Ko nga ahuatanga o te wai para whakangao: ① te kukū teitei, te waikawa kaha, te tae pouri me te paitini nui;② te hanganga o te puhui i roto i te wai para he tino pumau, kaore e ngawari te pirau, no reira ko nga tikanga whaanui penei i te whakauru waro whakahohe, te hikohiko me te rerenga e kore e taea te whakatutuki.Resin adsorbent he kaha adsorption me te regeneration kaha, a he pūmau ona āhuatanga tinana me te matū ka taea te whakamahi toutou.
Āhuatanga
Ko te hua parakore he karaihe kowhai marama, he karaihe ngira ranei.Ira whakarewa 80～82℃.Kohuatanga 202℃.Ka whakarewa noa i roto i te waiwaro wera, te etera me te benzene, kare e rewa ki te wai.
Whakaritenga
Ko te Ethylbenzene ka whakahiato ki te waikawa whakauru i te 30～35 ℃ kia whiwhi nitroethylbenzene.I muri i te whakamaroketanga, ka whiwhihia te p-nitroethylbenzene me te hua-tahi o-nitroethylbenzene.I te aroaro o te stearate cobalt catalyst, ka oxidized te p-nitroethylbenzene ki te hau i te 140-150 ℃ me te pehanga 0.2MPa ki te whiwhi p-nitroacetophenone.I horoia te hua tauhohenga ki te wai, kua whakakorehia, kua whakamarokehia, kua whakamarokehia, ka whakamaroke kia puta te hua kua oti.
tikanga p-Nitrobenzoyl chloride.
Haumaru
Kaore i te mohiotia te paitini.Ko nga taputapu whakangao me noho hau, me mau te kaiwhakahaere i nga taputapu whakamarumaru.
Ka whakakiia ki roto i nga pahu rino, i nga papa rakau ranei kua kapi ki nga peeke kirihou.Rokiroki ki tetahi wahi maroke me te hau.
