摘要：

It has been demonstrated that the spinodal model produces very well the isothermal compressibility of liquid methanol for a wide range of pressures and temperatures. We have used the pseudospinodal model further to determine pressure derivatives, first-order as well as secondorder of isothermal compressibility and bulk modulus for liquid methanol in the range of pressures (0-100 MPa) and temperatures (208.17 K-298.16 K). The results have been found to present close agreement with the available experimental data. We have also calculated the values of densities as a function of pressure and temperature for methanol using the Stacey equation of state.
