Özet
An equilibrium isotherm of benzylformic acid with phosphoric acid tributyl ester in carbon tetrachloride, decanol, kerosene, toluene, and xylene at 298 K has been studied. The equilibrium data are discussed in terms of partition coefficient (P), dimerization constant (D), overall equilibrium complexation constant (E), and loading factor (phi). Moreover, the distribution coefficient (K-D) and extraction efficiency (eta%) with phosphoric acid tributyl ester in CCl4 is 0.199 to 52.1 and 16.6 to 98.1; in decanol, 5.66 to 45.9 and 85 to 97.9; in kerosene, 0.03 to 73.2 and 2.9 to 98.7; in toluene, 0.381 to 70.3 and 27.6 to 98.6; and in xylene, 0.322 to 57.7 and 24.3 to 98.3, respectively. The extraction efficiency of benzylformic acid was found to be more than 95 % with all these diluents. Loading factor phi < 0.5 was observed and it indicates that only 1:1 benzylformic acid-phosphoric acid tributyl ester complex in above said diluents were formed. Furthermore, the values of overall equilibrium complexation are determined with the relative basicity model using experimental result.
