Abstract
The isothermal solubilities and the refraction indices, densities of t he saturated solutions in the quaternary system KCl-K2SO4-CO(NH2)(2)-H 2O were investigated at 25 degrees C for the first time. The isograms of the refraction indices, densities and water-content of the saturate d solutions corresponding to K2SO4 have been obtained. The phase diagr am of the quaternary system is simple cutectic type, in which there is a triple saturated point, KCl 14.06, K2SO4 0.51, CO(NH2)(2) 47.05, H2 O 38.38 (mass fraction x 10(2)).
