Experimental Evaluation of Velocity Constants for Ozone Interaction with Individual Fatty Acids

Resumo

The kinetics of ozone interaction with 14 saturated and unsaturated fatty acids with different molecular structures was studied and velocity constants of these reactions were measured. The relationships between the measured constants and some parameters of fatty acid (length of the aliphatic chain, number of double bonds, location of the double bonds, and its configuration) were detected. The highest velocity constant is recorded for monounsaturated oleic fatty acid: 2.58×10⁵ (M×sec)^—1. Other studied fatty acids had 1.5-5-lower constants depending on their molecular structures.
