Specific volumes, thermal pressure coefficients, and derived quantities of five dimethylsiloxane oligomers from 25 to 140.degree.C

Multiparameter equations of state for selected siloxanes

“…specific volume data at 1 atm in the liquid phase reported in Ref. [32]. The SW EoS for MM performs better than the PRSV EoS in representing the experimental data: the values calculated with the PRSV EoS deviate from experimental data by as much as 5.17%, while the maximum deviation for values calculated with the SW EoS for MM is 0.27%.…”

“…Atmospheric subcooled liquid specific volumes for MM and MD 4 M are reported in Ref. [32]. These authors indicate that the uncertainty in the specific volume data is 0.00005 cm 3 /g and show that the data are consistent.…”

Internal pressure measurements of the binary 0.7393H2O+0.2607NH3 mixture near the critical and maxcondetherm points

“…The acoustic method was used by Dzida [15] to calculate the internal pressure of cyclopentanol at pressures up to 100 MPa and at temperatures from 293 K to 318 K. McLure and Arriaga-Colina [16] reported thermal-pressure coefficient measurements for ethanenitrile, propanenitrile, and butanenitrile from 297 K to 398 K. Measurements were made with an apparatus consisting of a constant-volume thermometer in which the pressure is controlled and measured for a series of temperatures at a series of different constant densities. McLure et al [17] also measured of the thermal-pressure coefficient for five dimethylsilioxane oligomers in the temperature range from 298 K to 413 K. Thermal-pressure coefficients were measured in Pyrex cells (dilatometers). The sample was confined by mercury, and changes in its volume were monitored by weighing the amount of mercury expelled from or drawn into the dilatometer.…”
