Experiments have been carried out to determine the effect that added n-pentanol has upon the solubility of ethane gas in micellar solutions of sodium dodecyl sulfate. The results show that when micellar sodium dodecyl sulfate is present, n-pentanol acts to enhance gas solubility. However, the degree to which the alcohol enhances gas solubility varies with concentration. At low concentrations, the incremental increase in ethane solubility per mole of alcohol is found to be numerically about equal to the solubility of ethane in ethanol. This incremental change in gas solubility increases with pentanol concentration and approaches the solubility of ethane in pure pentanol at high ratios of alcohol to surfactant. Unusual gas-induced gels are formed at moderate pressures (p is approx. 5 atm) with ethane and homogeneous solutions having compositions bordering those of the liquid crystal-solution phase boundary.
