Abstract

This thesis was undertaken to augment and validate the previous work of Ratcliff and Reid(7) in the area of diffusion of immiscible liquids. Their novel approach to this particular problem of liquid diffusion led the author to consider an experimental technique that has been used in gas-liquid studies. A short vetted-wall column was used to determine the rate of mass transfer of benzene and toluene into thin cylindrical films of water. A general analytical solution for the rate of mass transfer has been derived and is given below. This solution was checked using the system benzene-water.

G=3.63(Π(ρωβ)g/μl)1/6 R2/3 L1/2 D1/2AB Q1/3 CRo

The calculated diffusivity from the experimental results for the system benzene-water with the author's above derived equation gave a result which was approximately thirteen percent lower than that reported by Ratcliff and Reid(7) in their study of the same system using spherical films of water.

The system toluene-water was also studied and data is presented.
