Compressed Liquid Densities and Saturated Liquid Densities of Dimethyl Ether (RE170)
dataset

but the available literature data for this fluid, especially in terms of liquid density, are scarce. In this
paper, compressed liquid density data were measured along eight isotherms between (283.15 and 353.15)
K up to 35 MPa with a vibrating tube densimeter (Anton Paar DMA 512) and, on the basis of these data,
the saturated liquid densities were estimated. The overall estimated uncertainty for the density data is
within ± 0.1 %. The experimental compressed liquid density data and the estimated saturated density
data were correlated by means of fitting equations that are also presented in this paper.
