This volume contains numerical values and a critical analysis of solubility data for ethane in pure liquids, liquid mixtures, aqueous and organic solutions, and electrolytes, at both low and high pressures. For each published paper, an individual data sheet contains the experimental solubility, a description of the experimental apparatus, the purity of the materials used, and the experimental error where available. For each solute/solvent system the solubility data are critically assessed and recommended solubility values are presented.
