| Abstract: The FTIR spectra of a series of naphthenic acid(HA)-Sodium(Potassium)Naphthenate systems with different acid -salt ratios were measured. The changes of the bands of O-H stretching and bending vibration, C=O stretching vibration, and COO- symmetric and asymmetric stretching all indicate that naphthenic acid-salt system is a complex system rather than a simple mixture of acid and salt. Strong chemical interactions including the coordination of acid to metal ions and the hydrogen bond between acid and salt exist in the system. Compositions of the acid-salt complexes arc determined to be KA·HA and NaA·HA. This result will be helpful to understand the biological acid-salt systems. | |
