Abstract

Many important industrial applications for fatty acids and their derivatives are based on the ability of the unsaturated members of a series to combine with other molecules through the reactivity of their double bonds.

Investigators for quite some time have sought means and methods for determining the number and the position of these double bonds and correlating the results as a means of identification for the unsaturation in fats and oils. Iodine addition to the double bond is employed generally in analytical work as a measure of unsaturation and as a means of separating acids of varying degrees of unsaturation. The iodine value or iodine number of fatty acids and oelfins are universally used to express the degree of unsaturation. There exists a very marked discrepancy between the theoretical and experimental results. When substitution values are high, the results are inaccurate and even incorrect.

The basis of this research is to develop an apparatus or semi-micro dimensions and of simple design so as to encourage the use of the more accurate hydrogen number determinations instead of the iodine numbers which are no in use to estimate the unsaturation of fats and oils.
