Under computer control the apparatus can make measurements over a range of composition x at constant T and p or over a range of p at constant x and T. Measurements of H m E and V m E for { xCO 2+(1 x)C 6H 5CH 3} have been made at 298.15, 304.10, and 308.15 K at ...
Measurements of HmE and VmE for {xCO2+(1−x)C6H5CH3} have been made at 298.15, 304.10, and 308.15 K at pressures up to 10.6 MPa. The HmE measurements at 308.15 K and 10.6 MPa are in good agreement with similar measurements made by Christensen and co-workers. Comparison has been ...
