The equilibrium sedimentation technique for the direct determination of the chemical potential composition derivatives of a liquid mixture is applied to the binary system acetone‐carbontetrachloride. Equilibrium concentration profiles obtained in an ultracentrifuge are used with the Wilson equation to quantitatively determine the composition variation of the activity coefficients over the entire range of composition. Results agree well with previous data and indicate the technique to be accurate and reliable.
