I-2-Chloro-4-nitrobenzoic acid CAS 99-60-5 Isicelo

Ifunyenwe nge-chlorination kunye ne-oxidation ye-p-nitrotoluene. Faka i-p-nitrotoluene kwi-reactor eyomileyo, emva kokufudumeza kunye nokunyibilika, yongeza ucingo lwentsimbi kunye neeflakes ze-iodine, kwi-58-62 â, ugqithise umlinganiselo olinganayo wegesi ye-chlorine, uhlambe ngamanzi ashushu, ungathathi hlangothi nge-sodium carbonate, kwaye ugalele amanzi e-ice, axutywe ukuba ahlukanise iikristale, ahluzwe ukususa amanzi, kwaye omiswe emthunzini ukufumana i-2-chloro-4-nitrotoluene. Emva koko yongeza amaxesha angama-25 e-1-2% isisombululo se-sodium hydroxide kwi-2-chloro-4-nitrotoluene, ukushisa kwi-Chemicalbook ebilayo, phantsi kokuvuselela ngamandla, ngokukhawuleza ukongeza i-potassium permanganate, gcina ubushushu kwi-100±1â, Emva kokongeza, qhubeka. xhokonxa, reflux for 30min, vumela kuphole, kwaye ukususa manganese dioxide. I-filtrate yahlengahlengiswa kwi-pH 1-2 nge-hydrochloric acid, i-precipitate ihlanjwe ngamanzi e-ice, ihlulwe kwaye yomiswe kwi-80 ° C ukuze ifumane imveliso. Umsebenzi wokucoca unokwenziwa kwakhona xa kukho i-ferric chloride, kwaye ugqithise iklorini kwi-58-62 ° C. Isivuno esipheleleyo se-chlorination kunye ne-oxidation malunga ne-70%.
