Solubilities of methane in binary mixtures of water and t-butyl alcohol (TBA) have been measured in the temperature range from 303.15 K to 333.15 K and at pressures up to 6 MPa. The mole fraction of t-butyl alcohol(x_(TBA)) in the mixed solvents varied from 0.0 to 1.0. The dependence of the solubilities on temperature and the composition of the mixed solvents can be explained by clathrate structure in the mixed solvents. The Henry s Law constans, the partial mole volumes of methane in the solvents, and the standard thermodynamic functions (ΔG°, ΔH°, ΔS°) have been calculated and discussed.
