| Abstract: | Based on the solubility law,the proper solvent was selected to separate and puritythe o-and p-nitrochlorobonzene.The polar organic solvents such as alcohol and their water solutions were used,in which the solubilities of o-and p-nitrochlorobonzene were investigated at different temperature,and the solubility effects were analyzed.As result,to o-and p-nitrochlorobonzene,there were more difference at the solubility,which was good at separating the mixture.As the water content increased,the solubilization capacity and the difference of solubilities got decreased,so the mixture's separation became more difficult.Considered of the technique and economics,the methanol containing proper ratio of water was selected as the solvent to research the o-and p-nitrochlorobonzenes' separation. |
