The solubility curves of m-aminophenol in the liquor of m-phenylene diamine and sodium sulfate were examined and established.Solubilities of m-aminophenol in the situation of different concentrations of m-phenylene diamine,quantitative sodium sulfate,various pH and their mixture were determined via HPLC.The experiments proved that the existence of a little amount of m-phenylene diamine had little effect on the solubility of m-aminophenol,and quantitative sodium sulfate made the solubility of m-aminophenol smaller,and m-phenylene diamine and sodium sulfate did not separate out along with MAP crystallization,and the lowest solubility of m-aminophenol was acquired at pH 7.08,with the solubility of MAP of only 0.013~0.032 g/mL below 30 ℃ in the mixture.
