Excess molar heat capacities for binary mixtures of isomeric xylenes h
ave been measured in the temperature range 303.65-321.65 K using a C-8
0 calorimeter. C(p,m)E is negative for o-xylene + m-xylene, o-xylene p-xylene, but positive for the system m-xylene + p-xylene. Our extrap
olated values at 298.15 K compare well with those reported by Fortier
and Benson [Fortier, J.L. and Benson, G.C., 1980. J. Chem. Eng. Data,
25: 47]. The results have been compared with Flory's theory of mixture
