| Abstract: | An apparatus for a rapid and simultaneous determination of the thermophysical properties excess enthalpy, isobaric heat capacity, kinematic viscosity, density and thermal conductivity has been developed. The experimental setup is subject of this paper. At 298.15 and 323.15 K, the systems ethylene glycol dimethyl ether–n-dodecane, diethylene glycol dimethyl ether–n-dodecane, triethylene glycol dimethyl ether–n-dodecane, tetraethylene glycol dimethyl ether–n-dodecane and diethylene glycol dibutyl ether–n-dodecane have been investigated. The experimental results are correlated and the macroscopic properties are interpreted. |
