摘　　要：The isothermal solubility of the ternary system Cu（NO3）2-EBU-H2O at 30℃has been studied for the first time and the solubility diagram and refractive indices diagram have been given. New phase Cu（NO3）2·2EBU has been found in this system, which dissolves incongruently in water .The phase has been characterized by element analysis, IR spectra and X ray diffraction powder analysis.The isothermal solubility of the ternary system Cu(NO_3)_2-EBU-H_2O at 30℃has been studied for the first time and the solubility diagram and refractive indices diagram have been given.
