Default Solubility of Butane in Polar Solvents

For gases of high solubility such as butane it has been shown that the gas normal boiling point can be considered as an extrapolation of the solubility relation; that is, as the saturation temperature is reduced, the solution becomes richer in the gas until as the temperature approaches the gas normal boiling point, the concentration of the saturated solution approaches that of the pure gas. It is hypothesized that this phenomenon occurs only when the solvent and liquefied gas are completely miscible at a temperature below the gas normal boiling point as is the case for butane and hexane.
Am I to understand this to mean butane will evaporate/boil off in a solution of butane and ethanol by simply rising to ambient/room temperature? Is butane completely miscible in ethanol at below gas normal boiling temperature?
