P-nitroacetofenone jẹ agbedemeji pataki ni iṣelọpọ Organic ati pe a lo bi ohun elo aise fun iṣelọpọ ti chlortetracycline ati chloramphenicol ninu oogun.Ọna ibile fun iṣelọpọ ile-iṣẹ ti p-nitroacetophenone jẹ ifoyina ti ethylbenzene.Ni afikun si ọja akọkọ p-nitroacetophenone, awọn ọja nipasẹ awọn ọja wa bi p-nitrobenzoic acid ninu eto ifaseyin.Omi idọti iṣelọpọ ni awọn abuda wọnyi: ① ifọkansi giga, acidity ti o lagbara, awọ dudu ati majele giga;② eto ti agbo inu omi idọti jẹ iduroṣinṣin pupọ ati pe ko ni irọrun biodegradable, nitorinaa awọn ọna gbogbogbo bii adsorption erogba ti mu ṣiṣẹ, itanna ati ojoriro ko le ṣaṣeyọri ipa ti o fẹ.Resini adsorbent ni adsorption to lagbara ati agbara isọdọtun, ati awọn ohun-ini ti ara ati kemikali jẹ iduroṣinṣin ati pe o le ṣee lo leralera.
Awọn ohun-ini
Ọja mimọ jẹ kirisita ofeefee ina tabi kirisita abẹrẹ.Oju yo 80~82℃.Oju omi farabale 202℃.Tiotuka larọwọto ni ethanol gbona, ether ati benzene, insoluble ninu omi.
Igbaradi
Ethylbenzene jẹ iyọ pẹlu acid adalu ni 30 ~ 35 ℃ lati gba nitroethylbenzene.Lẹhin distillation, p-nitroethylbenzene ati o-nitroethylbenzene àjọ-ọja ti wa ni gba.Ni iwaju ayase koluboti stearate, p-nitroethylbenzene ti wa ni oxidized pẹlu air ni 140-150 ℃ ati 0.2MPa titẹ lati gba p-nitroacetophenone.Ọja ifaseyin ti fọ pẹlu omi, didoju, centrifuged ati gbẹ, ati gbigbe lati fun ọja ti o pari.
