Diffusion Coefficients of (Copper Chloride + Theophylline + Water) at Temperatures of (298 and 310) K

A Taylor dispersion method has been used to measure ternary diffusion coefficients of three-component aqueous systems, D 11, D 22, D 12, and D 21, for aqueous solutions of CuCl2−theophiline at temperatures of (298 and 310) K at carrier concentrations from (0.000 to 0.010) mol·dm−3, for each solute,...

Summary:A Taylor dispersion method has been used to measure ternary diffusion coefficients of three-component aqueous systems, D 11, D 22, D 12, and D 21, for aqueous solutions of CuCl2−theophiline at temperatures of (298 and 310) K at carrier concentrations from (0.000 to 0.010) mol·dm−3, for each solute, respectively. The results are compared with these obtained for (H2O + CuCl2) and (H2O + 1,3-dimethyl-7H-purine-2,6-dione), also reported here.
