He mea koʻikoʻi ka P-nitroacetophenone i ka synthesis organik a hoʻohana ʻia ma ke ʻano he kumu waiwai no ka synthesis o chlortetracycline a me chloramphenicol i ka lāʻau lapaʻau.ʻO ke ala kuʻuna no ka hana ʻana o ka p-nitroacetophenone ʻo ka oxidation o ka ethylbenzene.Ma waho aʻe o ka huahana nui p-nitroacetophenone, aia nā huahana like ʻole e like me ka p-nitrobenzoic acid i ka ʻōnaehana pane.Loaʻa nā ʻano o ka wai ʻōpala hana: ① kiʻekiʻe kiʻekiʻe, ʻakika ikaika, kala ʻeleʻele a me nā mea ʻawaʻawa kiʻekiʻe;② paʻa loa ke ʻano o ka pūhui i loko o ka wai ʻino a ʻaʻole maʻalahi ka biodegradable, no laila ʻaʻole hiki i nā ʻano maʻamau e like me ka adsorption carbon activated, electrolysis a me ka ua hiki ʻole ke hoʻokō i ka hopena i makemake ʻia.Loaʻa i ka Resin adsorbent ka adsorption ikaika a me ka hiki ke hoʻoponopono hou, a paʻa kona mau kino kino a me nā mea kemika a hiki ke hoʻohana pinepine ʻia.
Waiwai
ʻO ka huahana maʻemaʻe he aniani melemele māmā a i ʻole ke aniani nila.Ka helu hehee 80~82 ℃.He 202 ℃ ka helu hoʻolapalapa.Hiki ke hoʻoheheʻe ʻia i ka ethanol wela, ka etera a me ka benzene, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
Hoʻomākaukau
Hoʻopili ʻia ka Ethylbenzene me ka ʻakika hui ʻia ma 30 ~ 35 ℃ e loaʻa ai ka nitroethylbenzene.Ma hope o ka distillation, loaʻa ka p-nitroethylbenzene a me ka co-product o-nitroethylbenzene.Ma ke alo o ka catalyst cobalt stearate, p-nitroethylbenzene i hoʻoheheʻe ʻia me ka ea ma 140-150 ℃ a me 0.2MPa kaomi e loaʻa ai ka p-nitroacetophenone.Ua holoi ʻia ka huahana hopena me ka wai, neutralized, centrifuged a dehydrated, a maloʻo e hāʻawi i ka huahana i hoʻopau ʻia.

Hoʻopili ʻia i loko o nā pahu hao a i ʻole nā pahu lāʻau i hoʻopaʻa ʻia me nā ʻeke plastik.E mālama i kahi maloʻo a me ka makani.
