The enthalpy of benzene

Specific enthalpy increments for propan-1-ol at temperatures up to 573.2 K and 11.3 MPa

“…The curve shown in figure 3(b) was calculated from equation (5). Agreement between the calculated enthalpy increments and those obtained by extrapolation of the …”

“…To calculate the two-phase envelope shown in figure 1, it is only necessary to add perfect gas enthalpies calculated from equation (5). As the ordinate in figure 1 is pressure rather than temperature, it is convenient to generate an equation which expresses the saturation temperature T sat as a function of the pressure.…”

“…These agreed with steam tables to within ±0.5 per cent. The calorimeter has been used to measure enthalpy increments for methanol, (2) ethanol, (3) propanone, (4) n-hexane, (1) benzene, (5) (propanone + n-hexane), (6,7) and (propanone + benzene). (8) Enthalpy increments for propan-1-ol are now reported.…”

Molar enthalpy increments for (0.5 H2O + 0.5 CH3OH) at temperatures up to 573.2 K and pressures up to 13.0 MPa

“…These agreed with steam tables to within 0.5 per cent. The calorimeter has been used to measure enthalpy increments for methanol, (2) ethanol, (3) propanone, (4) n-hexane, (1) benzene, (5) (propanone + n-hexane), (6) and (propanone + benzene). (7) A flow mixing calorimeter for the measurement of the excess molar enthalpy H E m of gaseous and near critical mixtures at temperatures up to 700 K and pressures up to 12 MPa has also been constructed and tested.…”

A flash vaporizing flow calorimeter for the measurement of enthalpy increments. Test measurements onn-hexane atT= 473.2 K andT= 510.2 K and pressures up top= 5.2 MPa

“…The results of 90 test runs on steam gave enthalpy increments in agreement with steam tables to within ± 0.5 per cent. This calorimeter was capable of operation at temperatures up to T = 700 K at pressures up to p = 15 MPa, and it has been used to measure enthalpy increments for n-hexane, (7) acetone, (8) methanol, (9) ethanol, (10) (acetone + n-hexane), (11,12) benzene, (13) and (acetone + benzene). (14) The calorimeter was operated manually, and would have been difficult to automate.…”
