The phase equilibrium data of CO(NH_2)_2-H_3BO_3-H_2O system at 25 ℃ and 35 ℃ have been presented and the phase diagrams have been drawn too. According to the diagrams, no complex salts of CO(NH_2)_2 and H_3BO_3 have formed in CO(NH_2)_2-H_3BO_3-H_2O system at 25 ℃ and 35 ℃.
By using the equation of Margules, the phase equilibrium data of CO(NH_2)_2-H_3BO_3-H_2O system at 25 ℃ and 35 ℃ have been calculated. The calculations coincide well with the experimental data.-
