Instability of mechanical equilibrium (diffusion instability) in ternary gaseous mixtures 0.250 C3H8 + 0.750 CO2 – N2O, 0.220 C3H8 + 0.780 CO2 – N2O and 0.196 C3H8 + 0.804 CO2 – N2O with equal molar mass components is studied experimentally. It is found out that the decrease of propane concentration in the initial binary mixture leads to the increase of pressure, under which the intensity of propane transfer reaches its maximum.
