M. Pajak et al., LIQUID-LIQUID EQUILIBRIUM IN THE SYSTEM ETHANOL-WATER TRIBUTYL-PHOSPHATE TOLUENE, Inzynieria Chemiczna i Procesowa, 18(2), 1997, pp. 269-277
The liquid-liquid equilibrium was measured in the system: water-ethano
l-50 wt % solution of tributyl phosphate (TBP) in toluene at 25 degree
s C. The parameters of the UNIQUAC model were determined by the method
of least squares from experimental tie lines data. The distribution a
nd selectivity curves of ethanol are presented and compared with the c
urves for the system in which pure TBP is applied as ethanol extractan
t.
