Paper Abstract

The FT-IR spectra and subtraction spectra of fifteen rare earth naphthenates in the extract phase have been studied with the following results: (1). The symmetrical stretching vibration band 04) of the carboxylate ion in the extracted rare earth naphthenates can not be found in the used FT-IR spectra, but we have found them in the subtraction spectra. (2). Then the differences between j),ms (asymmetrical frequency of COO ) and y can be obtained from which the coordination structure of rare earth naphthenates may Be discussed. (3). By this way, the effect of coordination of the secondary octyl alcohol (ROH) with the rare earth naphthenates was observed.
