โœฆ Synopsis

The dependence of the solubility of sodium octanoate in trioctanoin on the presence of octanoic acid was determined by solubility measurements at 20 ยฐC. The intermolecular forces which cause the formation of acid-soap aggregates were investigated by means of infrared and proton magnetic resonance spectra.

The results showed that soap-acid aggregates are formed, which initially contain three acid molecules per one soap molecule. Strong hydrogen bonds similar to those in solid "acid soaps" are found in the aggregates. When the soap content is in excess of 1 soap : 3 acids the polar part of the triglyceride has some interaction with the complexes, as shown by the pronounced broadening of the signal from the protons in the glycerol rest.

## Saponification of triglyceride oil emulsified in alkaline aqueous solution is found to proceed faster in presence of soaps from rosin acids than with soaps from fatty acids. The results are discussed in relation to differences in phase properties between the two types of soaps and applications
