2-Chloro-4-nitrobenzoic acid CAS 99-60-5 Codsiga

Waxaa lagu helaa chlorination iyo oksidation p-nitrotoluene. Geli p-nitrotoluene reactor engegan, ka dib kulaylka iyo dhalaalida, ku dar silig bir ah iyo flakes iodine, at 58-62 â, gudbi qadar u dhigma oo gaasta chlorine, ku dhaq biyo kulul, dhexdhexaad ah sodium carbonate, oo ku shub biyaha barafka , la walaaqay si loo kala saaro kiristaalo, la sifeeyay si looga saaro biyaha, oo lagu qalajiyo hooska si loo helo 2-chloro-4-nitrotoluene. Ka dib ku dar 25 jeer oo ah 1-2% sodium hydroxide xal 2-chloro-4-nitrotoluene, kulaylka karkarinta buugta Kiimikada, hoos aad u walaaqaya, si tartiib ah ugu dar potassium permanganate, heerkulka ku hay 100± 1â, ka dib markaad ku darto, sii wad walaaq, reflux 30min, qabooji, oo ka saar oksijiinta manganese. Shaandhaynta waxaa lagu hagaajiyay pH 1-2 leh hydrochloric acid, da'da waxaa lagu dhaqay biyo baraf ah, la sifeeyay oo la qalajiyey 80 ° C si loo helo alaabta. Hawlgalka koloriinaynta waxa kale oo la samayn karaa iyadoo ay jirto ferric chloride, oo wali koloriinku dhaafsiisan yahay 58-62°C. Wadarta wax-soo-saarka koloriinta iyo oksaydhisku waa ilaa 70%.
