P-nitroacetophenone yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab yog siv los ua raw khoom rau kev sib txuas ntawm chlortetracycline thiab chloramphenicol hauv tshuaj.Cov txheej txheem ib txwm siv rau kev tsim khoom ntawm p-nitroacetophenone yog oxidation ntawm ethylbenzene.Ntxiv nrog rau cov khoom tseem ceeb p-nitroacetophenone, muaj cov khoom lag luam xws li p-nitrobenzoic acid hauv cov tshuaj tiv thaiv.Cov dej khib nyiab ntau lawm muaj cov yam ntxwv hauv qab no: ① siab concentration, muaj zog acidity, tsaus xim thiab siab toxicity;② cov qauv ntawm cov khoom siv hauv cov dej khib nyiab yog qhov ruaj khov thiab tsis yooj yim biodegradable, yog li cov txheej txheem dav dav xws li cov pa roj carbon adsorption, electrolysis thiab nag lossis daus tsis tuaj yeem ua tiav cov txiaj ntsig xav tau.Resin adsorbent muaj zog adsorption thiab rov tsim dua tshiab, thiab nws lub cev thiab tshuaj muaj zog ruaj khov thiab tuaj yeem siv tau ntau zaus.
Cov khoom
Cov khoom ntshiab yog lub teeb daj siv lead ua los yog koob siv lead ua.Melting point 80 ~ 82 ℃.Kub taw tes 202 ℃.Dawb soluble nyob rau hauv kub ethanol, ether thiab benzene, insoluble nyob rau hauv dej.
Kev npaj
Ethylbenzene yog nitrated nrog tov acid ntawm 30 ~ 35 ℃ kom tau nitroethylbenzene.Tom qab distillation, p-nitroethylbenzene thiab co-product o-nitroethylbenzene tau txais.Nyob rau hauv lub xub ntiag ntawm catalyst cobalt stearate, p-nitroethylbenzene yog oxidized nrog cua ntawm 140-150 ℃ thiab 0.2MPa siab kom tau p-nitroacetophenone.Cov khoom siv tshuaj tiv thaiv tau ntxuav nrog dej, nruab nrab, centrifuged thiab dehydrated, thiab qhuav kom muab cov khoom tiav.
p-Nitrobenzoyl chloride txoj kev.
Kev nyab xeeb
Toxicity tsis paub.Cov khoom siv ntau lawm yuav tsum yog airtight thiab tus neeg teb xov tooj yuav tsum hnav cov iav tiv thaiv.
Ntim hauv cov nruas hlau lossis ntoo nruas kab nrog cov hnab yas.Khaws rau hauv qhov chaw qhuav thiab ventilated.
