The molar excess enthalpies of cyclohexane+methanol were systematically measured with a Picker flow microcalorimeter operated in discontinuous mode at 298.15 303.15, 308.15, 313.15, 318.15 and 323.15 K. Our values are higher than the literature data. This work shows that the molar excess enthalpies increase with tem- perature, and the straight segments of the excess enthalpy curves in the mid become shorter with the increasing of temperature. At 323.15 K the sample becomes one of a miscible liquid system, and the position of themaximum value of molar excess enthalpies is at x=0.6. In addition, the calorimetric measurement can be used to determine the compositions of two immiscible phases for the binary mixture.
