P-nitroacetophenone yakakosha yepakati mune organic synthesis uye inoshandiswa seyakabikwa yekugadzira chlortetracycline uye chloramphenicol mukurapa.Nzira yechinyakare yekugadzirwa kwemaindasitiri kwep-nitroacetophenone ndiyo oxidation ye ethylbenzene.Pamusoro pechigadzirwa chikuru p-nitroacetophenone, kune-zvakagadzirwa senge p-nitrobenzoic acid mune reaction system.Mvura yetsvina yekugadzira ine zvinotevera hunhu: ① yakakwira, acidity yakasimba, ruvara rwakasvibira uye huturu hwepamusoro;② chimiro chekomboni mumvura yetsvina yakanyatsogadzikana uye haisi nyore kuparara, saka nzira dzakajairwa senge activated kabhoni adsorption, electrolysis uye kunaya kwemvura haigone kuwana mhedzisiro yaunoda.Resin adsorbent ine adsorption yakasimba uye kugona patsva, uye yayo yemuviri uye makemikari zvimiro zvakagadzikana uye zvinogona kushandiswa kakawanda.
Properties
Chigadzirwa chakachena chiyero chekiristaro kana tsono crystal.Kunyungudika 80～82℃.Boiling point 202 ℃.Kunyungudika pachena mu ethanol inopisa, ether uye benzene, isinganyunguriki mumvura.
Kugadzirira
Ethylbenzene inoiswa nitrated neasidhi yakasanganiswa pa30～35℃ kuti iwane nitroethylbenzene.Mushure mekuita distillation, p-nitroethylbenzene uye co-chigadzirwa o-nitroethylbenzene inowanikwa.Pamberi pe catalyst cobalt stearate, p-nitroethylbenzene yakasvibiswa nemhepo pa 140-150 ℃ uye 0.2MPa kumanikidzwa kuwana p-nitroacetophenone.Chigadzirwa chacho chakashambidzwa nemvura, chisina kucheneswa, centrifuged uye chakaomeswa, uye chakaomeswa kupa chigadzirwa chakapedzwa.
p-Nitrobenzoyl chloride nzira.
Safety
Muchetura hauzivikanwi.Midziyo yekugadzira inofanirwa kunge isina mhepo uye mushandisi anofanira kupfeka giya rekudzivirira.
Yakaiswa mumadhiramu esimbi kana kuti madhiramu emapuranga akaiswa masaga epurasitiki.Chengetedza munzvimbo yakaoma uye ine mhepo.
