摘要：

Ternary mutual diffusion coefficients measured by the Taylor dispersion method are reported for aqueous solutions of CaCl2-caffeine at carrier concentrations from (0.0025 to 0.0500) mol.dm(-3) for each solute, respectively. The results are compared with those obtained for the binary systems H2O-CaCl2 and H2O-caffeine, also reported here. From these data, it is possible to make conclusions about the influence of the caffeine solutes in the diffusion of calcium chloride and to contribute to a better understanding of the structure of this system.
