ABSTRACT
The isobaric specific heat capacity and density for dimethyl ether were measured in the temperature range from (310 to 360) K at pressures up to 5 MPa in the liquid state. Measurements were conducted by the metal-bellows calorimeter. The uncertainties of isobaric specific heat capacity and density measurements were estimated to be less than 5 % and 0.2 %, respectively. Experimental values for the isobaric specific heat capacity and density were correlated as functions of pressure and temperature. In addition, the saturated liquid isobaric specific heat capacity and saturated liquid density were obtained from extrapolation of these correlations to the vapor pressure.
