Abstract Measurements of specific enthalpy increments for butan-1-ol are reported. A counter-current water-cooled flow calorimeter was used to measure 109 enthalpy increments over the temperature range of 423.2 to 623.2 K at pressures from 0.1 to 10.2 MPa. Extrapolation of the gas phase measurements to zero pressure gave values in close agreement with pure-component ideal-gas enthalpies calculated by extrapolation of data on the lower alcohols. 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.
