Recommended vapor pressures for thiophene, sulfolane, and dimethyl sulfoxide

“…Any correction made would be much smaller than the experimental uncertainty of our measurements themselves and can be neglected. The correction does not exceed 0.1% even for much more volatile compounds when the volume of the condensed phase is about 3/4 of the total volume of the measuring cell [15,17]. The saturated molar heat capacities C sat,m obtained in this work are identical to isobaric molar heat capacities C p,m in the temperature range studied as it is not necessary to make a clear distinction between C p,m along the saturation curve and C sat,m below 0.9 T b , where T b is the normal boiling temperature [16].…”

Effects of hydration on the thermodynamic properties of aqueous ethylene glycol ether solutions

“…The reproducibility of the c p values was usually better than 0.1%, the overall uncertainty of the measurement estimated from calibration and test experiments is assumed to be $0.3%. No allowances were made for sample vaporization and gas phase corrections as the vapor volume was kept below 10% of the total cell volume and all substances have quite low vapor pressures at the measurement temperature [11].…”
