Excess molar enthalpies of the ternary system { x 1 p-xylene+ x 2decane+(1– x 1– x 2)diethyl carbonate} and the involved binary mixtures { p-xylene+(1– x)decane}, { xp-xylene+(1– x)diethyl carbonate} and { xdecane+(1– x)diethyl carbonate} have been determined at the temperature of 298.15 K and atmospheric pressure, over the whole composition range, using a Calvet microcalorimeter. The experimental excess molar enthalpies H mE are positive for all the binary systems studied over the whole composition range. Excess molar enthalpy for the ternary system is positive as well, showing maximum values at x 1=0, x 2=0.4920, x 3=0.5080, H m,123E=1524 J mol–1.
