I-P-nitroacetophenone yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye isetyenziswe njengento ekrwada yokwenziwa kwe-chlortetracycline kunye ne-chloramphenicol kumayeza.Indlela yendabuko yokuveliswa kwemveliso ye-p-nitroacetophenone yi-oxidation ye-ethylbenzene.Ukongeza kwimveliso ephambili ye-p-nitroacetophenone, kukho imveliso efana ne-p-nitrobenzoic acid kwinkqubo yokusabela.Amanzi amdaka emveliso anezi mpawu zilandelayo: ① ukugxila okuphezulu, iasidi eyomeleleyo, umbala omnyama kunye netyhefu ephezulu;② Ubume bekhompawundi kumanzi amdaka izinzile kwaye ayiboli lula, ngoko ke iindlela eziqhelekileyo ezifana nekhabhoni esebenzayo, i-electrolysis kunye nemvula ayinakufezekisa umphumo oyifunayo.I-resin adsorbent ine-adsorption enamandla kunye nekhono lokuvuselela, kwaye iimpawu zayo zomzimba kunye neekhemikhali zizinzile kwaye zinokusetyenziswa ngokuphindaphindiweyo.
Iipropati
Imveliso ecocekileyo yikristale etyheli okanye ikristale yenaliti.Indawo yokunyibilika 80℃ 82℃.Indawo yokubilisa 202℃.Inyibilika ngokukhululekileyo kwi-ethanol eshushu, i-ether kunye ne-benzene, enganyibilikiyo emanzini.
Ukulungiselela
I-Ethylbenzene ifakwe kwi-asidi exutyiweyo ku-30～35℃ ukufumana i-nitroethylbenzene.Emva kwe-distillation, i-p-nitroethylbenzene kunye ne-co-product o-nitroethylbenzene ifunyenwe.Xa kukho i-catalyst cobalt stearate, i-p-nitroethylbenzene i-oxidized ngomoya kwi-140-150 ℃ kunye ne-0.2MPa yoxinzelelo lokufumana i-p-nitroacetophenone.Imveliso yokusabela ihlanjwe ngamanzi, ingathathi hlangothi, i-centrifuged kunye ne-dehydrated, kwaye yomiswe ukunika imveliso egqityiweyo.
p-Nitrobenzoyl chloride indlela.
Ukhuseleko
Ubutyhefu akwaziwa.Isixhobo sokuvelisa kufuneka singangeni moya kwaye umsebenzisi kufuneka anxibe izixhobo zokukhusela.
Ipakishwe kwimigqomo yentsimbi okanye igubu leplanga elifakwe kwiingxowa zeplastiki.Gcina kwindawo eyomileyo nengena umoya.
