The isothermal solubility of methane in methanol was measured at temperatures from 213.15 K to 273.15 K and pressures from 1.0580 MPa to 6.9947 MPa. The static analytical method was used in the experiment, which was carried out by sampling from an equilibrium cell using a heated sample cylinder connected to a gas chromatograph and loading the sample into the chromatograph. The Soave–Redlich–Kwong equation of state with the van der Waals one-fluid mixing rule applying the Wilson activity coefficient model with Henry’s constant was used to describe the equilibrium behaviour of vapour and liquid phase in the system for (methane + methanol) binary mixture. The measurements were correlated with the SRK-vdW-Wilson-Henry model. The calculated results indicate that the model not only matches well with the measurements but also predicts optimally VLE data of the system from 213.15 K to 273.15 K below 7.0000 MPa.
