โœฆ Synopsis

Measurements of specific enthalpy increments for propan-2-ol are reported. A countercurrent water-cooled flow calorimeter was used to measure 85 enthalpy increments over the temperature range 423.2 K to 563.2 K at pressures from 0.1 MPa up to 11.3 MPa. Extrapolation of the gas phase measurements to zero pressure gave values in excellent agreement with pure component ideal gas enthalpies calculated from spectroscopic data. Values of the specific enthalpy of vaporization derived from the measurements are in agreement with other work and are well fitted by a modification of the Watson equation. A method for the calculation of the two phase enthalpy-pressure envelope is described.
