IHS ESDU Orthobaric densities and molar volumes of liquids. Aliphatic and aromatic ethers. 95017

ESDU 95017 tabulates from near the melting point to the critical point density in kg/cu m at 5 degree C intervals and molar volumes in cu cm/mol at 5 K intervals for 36 ethers from C2 to C10. For a few compounds the correlation is stopped at around 0.95 critical. Another table gives at specified Celsius temperatures the density, molar volume and their derivatives with respect to temperature. The critical density was calculated using the Rackett and Riedel equations, which were in close agreement, and critical temperature and pressure were adjusted to give the best correlation of experimental results extracted from the literature for both the density data given here and the vapour pressure data given for these compounds in ESDU 95016. The equation used to fit the density data related reduced density to a polynomial in reduced temperature. The coefficients in the equation are given for each compound together with estimates of the accuracy of the predictions using them and a list of sources of data used. Values at the critical point are also given together with normal boiling and melting points.
