Abstract:
We have determined the heats of hydrogenation of the Cj6 and Cib unsaturated and poly
unsaturated fatty acids, palmitoleic, oleic, elaidic, linoleic, linelaidic and linolenic acids. This
paper reports and interprets the results in the light of previous experimental measurements and
theoretical predictions. Heats of formation follow from Hess’ Law addition to the reliable values
of the heats of formation of the hydrogenation products, hexadecanoic (palmitic) and octadecanoic
(stearic) acids. Our results are generally in serious disagreement with the scattered experimental
data and predictions gleaned from the literature and represent, we think, a significant improvement
over them.
