Abstract  

The extraction of HCl, HBr, HNO3, HClO4, H2SO4 and CH3COOH into solutions of 4-(5-nonyl)pyridine (NPy) and 2-hexylpyridine (HPy) dissolved in benzene has been studied. The results show that the larger, less basic anions extract better (ClO 4 >CH3COO≥NO 3 >Br>Cl>HSO 4 ) due to their low aqueous hydration. The ionization constants of NPyH+ and HPyH+ as determined spectrophotometrically were found to be 5.97±0.06 and 5.94±0.05, respectively, at 25°C.
