Study on Synthesis and Purification of 3,4-Dichoronitrobenzene

WU Wei-guo;GU Gao-wei;SUN Wen-peng;TAO Bin-bin;ZHANG Xue-fang;RUAN Cai-fang;Zhejiang Runtu Co., Ltd.;  
3,4-Dichloronitrobenzene was synthesized from o-dichlorobenzene using mixed acid as nitration agent.Selectivity of the synthesized product was affected by the reaction temperature, the molar ratio and dehydration value of mixed acid(DVS). The product was purified by alcohol to remove the by-product 2,3-dichloronitrobenzene, and the effects of alcohol concentration and dosage on the purification effect werealsoanalyzed.
