Abstract

The elastic properties of methane-propane mixed gas hydrate with cubic structure II (MPH-sII) have been determined as a function of pressure by high-pressure Brillouin spectroscopy up to 1.30 GPa at 296 K. The pressure dependences of the obtained ratios of elastic constants to density C₁₁/ρ and C₄₄/ρ of MPH-sII are obviously different from those of pure methane hydrate with cubic structure I (MH-sI), and indicate that the crystal of MPH-sII is elastically soft and weak against the shear stress in comparison with that of MH-sI under high pressure. Those results suggest that the elastic properties and structural stability of gas hydrates depend on not only the guest molecule but also the gas hydrate structure.<br>
