Solubility and refractive index data have been measured for the saturated ternary systems CH3OH + CSNO3 + H2O, C2H5OH + CSNO3 + H2O, 1-propanol + CsNO3 + H2O, 2-propanol + CSNO3 + H2O, and 2-methyl-2-propanol + CsNO3 + H2O at (25, 35, and 45) degrees C. In all cases, the presence of alcohol significantly reduces the solubility of cesium nitrate in aqueous solution. The solubility data and the alcohol content in the mixtures were correlated to an empirical equation.
