Mutual diffusion coefficients for the CO2sngbnd;CH4system were measured from 293 to 370deg;K. These measurements extend the temperature range of the previously measured values by about 75deg;K. The experimental values of the diffusion coefficient are in excellent agreement with values derived from the composition dependence of the viscosity of CO2sngbnd;CH4mixtures provided the quantityA12*which appears in the relation between the two transport properties is evaluated using experimental quantities.
