摘要：

A new apparatus based on a static method using a variable volume cell, for measurements up to 20 MPa and 353 K, is presented. The cylindrical part of the cell, made of transparent sapphire, allows direct optical measurements of phase volumes. The phase volumes, along with total numbers of moles of each component at given pressure and temperature, are measured for three loadings (differing only by total composition); their values are introduced in mass balance equations to calculate mole fractions in each phase and the three saturated molar volumes. Comparisons are made between present results, those published by Hottovy et al. (1981) on the carbon dioxide-tetradecane system, and those published by Briones et al. (1987) on the carbon dioxide-acetic acid and carbon dioxide-water-acetic acid systems. © 1990.
