Excess molar enthalpies of {xCH(3)(CH2)(2)OH or x-CH3CH(OH)CH3 + (1 - x)CH3C(CH3)(2)OCH3} and {x(1)CH(3)(CH2)(2)OH or x(1)CH(3)CH(OH)CH3 + x(2)CH(3)C(CH3)(2)OCH3 + (1 - x(1) - x(2))C6H6}, measured with a flow microcalorimeter at the temperature 298.15 K, are reported. The experimental results have been correlated with polynomial equations and compared with those calculated from an association model based on mole-fraction statistics having binary and ternary parameters.
