N2 - An electrical-matching, flow calorimeter was used to measure the enthalpies of ethylbenzene (349-551 K, 1.5-200 bar), Isooctane (358-520 K, 20-100 bar), and ethylcyclohexane (335-576 K, 20-100 bar). Water/steam calibration measurements show the apparatus capable of 0.1-0.2% precision with no detectable systematic bias. The present measurements are shown to be accurate to ±0.25% in enthalpy and ±2% in heat capacity. Literature vapor pressures, heats of vaporization, and perfect gas state enthalpies, consistent with the present hydrocarbon enthalpies, are used with our results to provide pressure/enthalpy diagrams for both the liquid and vapor states.
