Diffusivity of Methane in a Mixture of CCl(4) and c-C(6)F(11)C(2)F(5) of the Critical Composition in the Region above the Temperature of Separation.
The diffusivity of CH(4) in a mixture of CCl(4) and c-C(6)F(11)C(2)F(5) of the critical composition in the region of temperature close to that of unmixing, decreases as in a homogeneous liquid from 36 degrees to about 32 degrees . It then passes through a minimum of 10(5)D approximately 4.15 cm(2)/sec at about 27.5 degrees , then rises to 10(5)D = 4.61 at 25.00 degrees , then steeply to 6.36 cm(2)/sec in the further drop of only 0.3 degrees to 24.71 degrees .
