Experiments were also carried out to study the physical extraction as well as effect of TOA concentration on KD was also observed for extraction of SA. In physical extraction, the highest KD was obtained for benzyl alcohol that is 0.7 but it was very less as compared to the KD of TOAbenzyl alcohol mixture. Also the KD of 2-octanol and 1-decanol for physical extraction was 0.28 And 0.13 respectively. Figure . shows that as increase in the TOA concentration from 0.11 to 0.57 mol/kg, the KD also increase.
