Vibrational Spectroscopic Studies on the Acid Salts of Myristic Acid and Palmitic Acid

Abstract

Abstract: Fatty acids and their alkali soaps were well known as the biosurfactants in living system,however,little work had been published on the fatty acid-soap complexes,which were suggested here to have some unusual structures and properties.The acid sodium salts and acid potassium salts in molar ratio of 1:1 of both myristic acid and palmitic acid were investigated by FTIRand FT-Raman spectroscopies.The spectral results showed that very strong hydrogen bonds existed in these long-chain acid salts.In this paper,the possible structures of acid soaps were discussed according to spectroscopic data.

Key words: Fatty acid, Hydrogen bond, Infrared spectra, Raman spectra
