PRESSURE AND TEMPERATURE-DEPENDENCE OF SELF-DIFFUSION IN FLUID BINARYPROPANE TETRADECANE MIXTURES

Self diffusion data were measured for both compounds of the binary pro pane/tetradecane mixture by the NMR pulsed gradient spin echo techniqu e. A new autoclave for the investigation of binary gas/liquid mixtures in the fluid range up to pressures of 200 MPa is presented. The activ ation energies and volumes of both components are found to be identica l for the mixtures under investigation (2.5 and 89 mol% propane).
