摘要
本文测量了一系列不同组成的环烷酸－环烷酸钠（钾）酸盐体系的红外光谱，结果表明酸盐体系并不是简单的混合物，而是存在较强的相互作用，包括酸与盐之间的氢键作用和配位作用，体系中存在着组成为ＫＡ·ＨＡ和ＮａＡ·ＨＡ及更多种类的酸盐缔合物．
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.
