I-China P-Nitroacetophenone Manufacture Supplier Isithombe Esifakiwe

I-P-Nitroacetophenone

Incazelo emfushane:

Izilamuli zokwenziwa kwe-organic kanye nokuhlanganiswa kwemithi (njenge-synthomycin, i-chloramphenicol).Ibuye isetshenziswe ekuhlanganiseni izibulala-zinambuzane, odayi nezinongo.

I-P-nitroacetophenone iyingxenye ebalulekile ekuhlanganiseni kwe-organic synthesis futhi isetshenziswa njengempahla eluhlaza yokuhlanganiswa kwe-chlortetracycline ne-chloramphenicol kwezokwelapha.Indlela yendabuko yokukhiqizwa kwezimboni ze-p-nitroacetophenone i-oxidation ye-ethylbenzene.Ngaphezu komkhiqizo oyinhloko i-p-nitroacetophenone, kunemikhiqizo efana ne-p-nitrobenzoic acid ohlelweni lokusabela.Amanzi angcolile akhiqizwayo anezici ezilandelayo: ① ukugcwala okuphezulu, i-asidi eqinile, umbala omnyama nobuthi obuphezulu;② Isakhiwo senhlanganisela emanzini angcolile izinzile futhi ayiboli kalula, ngakho-ke izindlela ezijwayelekile ezifana ne-activated carbon adsorption, i-electrolysis kanye nemvula azikwazi ukufeza umphumela oyifunayo.I-resin adsorbent inamandla okukhangisa nekhono lokuvuselela, futhi izakhiwo zayo ezingokomzimba namakhemikhali zizinzile futhi zingasetshenziswa ngokuphindaphindiwe.
Izakhiwo
Umkhiqizo ohlanzekile uyikristalu eliphuzi elikhanyayo noma ikristalu yenaliti.Iphoyinti lokuncibilika 80～82℃.Iphoyinti lokubilisa 202 ℃.Incibilika ngokukhululeka ku-ethanol eshisayo, i-ether ne-benzene, engancibiliki emanzini.
Ukulungiselela
I-Ethylbenzene ixutshwe ne-asidi exutshwe ku-30～35℃ ukuze ithole i-nitroethylbenzene.Ngemuva kokukhishwa kwe-distillation, i-p-nitroethylbenzene kanye ne-co-product o-nitroethylbenzene iyatholakala.Lapho kukhona i-catalyst cobalt stearate, i-p-nitroethylbenzene ifakwe i-oxidized ngomoya ku-140-150℃ kanye nengcindezi engu-0.2MPa yokuthola i-p-nitroacetophenone.Umkhiqizo wokusabela ugezwe ngamanzi, ungathathi hlangothi, ufakwe i-centrifuged futhi uphelelwe amanzi, futhi womiswe ukunikeza umkhiqizo ophelile.
p-Nitrobenzoyl chloride indlela.
Ukuphepha
Ubuthi akwaziwa.Impahla yokukhiqiza kufanele ingangeni moya futhi oyisebenzisayo kufanele afake izinto zokuzivikela.
Ipakishwe ezigubhu zensimbi noma izigubhu zokhuni ezifakwe izikhwama zepulasitiki.Gcina endaweni eyomile futhi engenawo umoya.
