EVALUATION OF LINEAR CORRELATION FACTOR IN DILUTE BINARY-MIXTURES - TRI-N-BUTYL PHOSPHATE WITH NON POLAR-SOLVENTS

Linear correlation factor in very dilute solutions of binary mixtures of Tri-n-butyl phosphate (TBP) (mole fraction < 0.1) in seven non pola r solvents namely carbontetrachloride, n-hexane, n-heptane, carbon dis ulphide, benzene, p-xylene and cyclohexane at 303 K is determined and extrapolated to zero concentration of solute. In case of binary mixtur e of TBP in tetrachloromethane, n hexane, n-heptane and benzene, g dec reases whereas in case of binary mixture of TBP in p-xylene, carbon di sulphide and cyclohexane, g increases as mole fraction of TBP tends to zero.
