Abstract

Excess molar enthalpies of the ternary system {x1p-xylene+x2decane+(1–x1x2)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 HmE 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 x1=0, x2=0.4920, x3=0.5080, Hm,123E=1524 J mol–1.
