“…Only the work by Thomas and Smith [41] provides values that are in reasonable agreement with the present data. Some sets of data ( [42][43][44][45][46]) seem to disagree with current measurements, and some give a constant value of enthalpy of vaporisation over a temperature interval, which agrees with the present data at a single temperature ( [47][48][49]). Note also that enthalpy of vaporisation calculated from vapour-pressure data by Yi et al [50] is out of the scale of figure 2.…”

“…The vapor pressure of diethyl phthalate at 360 O K is less than 0.2 mm Hg [2]. The corresponding correction from Cobs to Cp (p = 1 atm) is about 0.002 percent of the value , and thus is disregarded.…”

Experimentally determined heat capacity valu es, precise to within 0.1 percent, and related thermal data are reported for quenched and annealed diethyl phthalate glasses from ]0 oK to the glass transformation te mperature, Tg (around 180 O K) , for the liquid from T" to 360 oK, and for the crystal from 10 oK to the melting temperature (269.9 O K). The mole fraction of liquid·soluble, solid·insoluble impurity in the sample as determined by fractional melting was 0.0012. Co mmon thermodynamic properties calc ulable from the experimental data are reported. The heat capacities of the two glasses differ by more than the uncertainty of the meas urements, and both lie below that of the crystal in the range from 30 to 75 oK. At low temperatures, just above 10 oK, the heat capacities of the glasses rise as much as 8 percent above that of the crystal.

“…High scatter of their data was observed, in particular at pressures below about 200 Pa. The data by Small et al, (23) measured in the very low-pressure region by the mass-loss effusion method (upper pressure limit around 4 Pa), exhibited large negative deviations. Data reported by Bruner and Sherwood (24) in a study of the properties and reactivity of diglycolic acid exhibit good agreement with our recommendation.…”
