Excess molar enthalpies of the ternary system p-xylene+decane+diethyl carbonate

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 m 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,123 =1524 J mol.
