Using two apparatus developed in this study, P-V-T relation, at 350.00, 360.00, 370.00, 390.00, and 402.00 K, and vapor pressure, in the range from 238.31 to 397.67 K, were measured for dimethyl ether (DME). Based on corresponding state theory, the constants in Benedict-Webb-Rubin (BWR) equation of state were determined for DME. The calculation results showed good reproducibility for the experimental data of P-V-T relation and vapor pressure. Applying some thermodynamic relations, we predicted not only latent heat of vaporization, isobaric heat capacity, and speed of sound for pure DME but vapor-liquid equilibrium of the binary and ternary mixtures containing DME and light hydrocarbons.
