Aa. Povodyrev et al., THERMODYNAMIC BEHAVIOR OF MIXTURES OF METHANE AND ETHANE IN THE CRITICAL REGION, International journal of thermophysics, 14(6), 1993, pp. 1187-1200
An isomorphic equation of state for near-critical binary mixtures is u
sed to represent equation of state and specific heat data for mixtures
of methane and ethane in a substantial range of densities and tempera
tures around the critical line.
