J. Bian et al., VIBRATIONAL SPECTROSCOPIC STUDIES ON THE ACID SALTS OF MYRISTIC ACID AND PALMITIC ACID, Gaodeng xuexiao huaxue xuebao, 17(3), 1996, pp. 432-435
Fatty acids and their alkali soaps were well known as the biosurfactan
ts in living system, however, little work had been published on the fa
tty acid-soap complexes, which were suggested here to have some unusua
l 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 FTIR and FT-Raman spectroscopies. The spectral re
sults showed that very strong hydrogen bonds existed in these long-cha
in acid salts. In this paper, the possible structures of acid soaps we
re discussed according to spectroscopic data.
