Investigation of the system: tri-n-butyl phosphate-n-tetradecane by gas-liquid chromatography.
The interaction of tri-n-butyl phosphate (TBP) with various solutes has been investigated by gas-liquid chromatography (GLC). In the case of benzene and chloroalkane solutes, the formation of 1:1 complexes has been assumed. The nonlinear behaviour of partition coefficients of the solutes with high TBP concentration in an inert solvent (n-tetradecane) has been explained in terms of the dimerization of TBP. Infinite dilution activity coefficients of the solutes and the corresponding excess partial molar functions have also been determined between 25.00 and 50.00 degrees C in increments of 5 degrees C.
