ABSTRACT

Critical properties of dimethyl ether (DME, RE-170) and its three binary mixtures with hydrocarbons, propane (HC-290), butane (HC-600), and 2-methyl propane (HC-600a), were measured with uncertainties of +-10 mK in temperature, +-0.5 kPa in pressure, +-1 kg m-3 in density, and +-0.5% in composition. The experimental data were correlated by equations proposed by Higashi.
