Abstract:

The extraction regularities have dramatic importance for purposes of the indirect pH potentiometric determination of acidic number in vegetable oils. This electroanalytical process includes the following steps:the mass transfer of fatty acids (steannic, oleininc et al) substantially through the oil - mixed solvent interface, and chemical interactions with participation of various reagents, namely, weak bases in excess or traces of strong bases, and redox - pairs of iodat - iodide ions, and any procedures of usual or automated potentiomeiric measurements.
