Liquid-Vapor and Solid-Vapor Equilibrium in the System Hydrogen-Ethane
The lowest temperature at which gas phase compositions for the hydrogen-ethane system have been published is 144.26°K, from the work of Williams and Katz . These investigators reported liquid-vapor equilibria data in 1954 for six isotherms from 102.59° to 283.15°K, up to 544 atm. However, gas phase compositions were not determined at the lowest temperature. In 1941, Levitskaya  reported liquid-vapor equilibria data for the binary and the ternary systems of hydrogen, methane, and ethane at 10° intervals from 158.15° to 188.15°K, at 30, 40, and 80 atm. In 1932, Uehara  reported very limited measurements for the solubility of hydrogen in liquid ethane for five temperatures, from 139.15° to 149.15°K at 1 atm total pressure.
