Figure 2
Molecular volume (V/Z) of DME, DEE and DPE plotted as a function of pressure: solid high-pressure (circles, this work) and low-temperature [diamonds (André et al., 1972BB1; Vojinović et al., 2004BB23)] phases as well as liquid DEE [triangles (Bridgman, 1913BB4)]. Open circles indicate the Vm values estimated at the freezing-pressure points. The vertical dashed lines mark the solid–solid transition pressure points (this work). The ambient- and high-pressure points at 295 K are joined by dashed lines. The solid lines between points are guides for the eye only. The estimated standard deviations are smaller than the plotted symbols.
