The method of estimating the glass transition pressure is proposed. A constitutive equation of viscoelastic solid mechanics such as a 3-parameter model is employed for analyzing pressure relaxation behavior of liquids at constant strains. In generating high pressures up to 15 GPa, a diamond-anvil high-pressure device and the ruby fluorescence pressure sensing method were employed. The glass transition pressures at room temperature of 4Methanol-1Ethanol and 16Methanol-3Ethanol-1Water obtained by this method are 10.6 GPa and 12.3 GPa respectively. These values show good agreement with the existed values which obtained from the ruby fluorescence line broadening method.
