Kinetics of gas—liquid ozonization of veratrole and its derivatives

A. G. Khudoshin, A. N. Mitrofanova, and V. V. Lunin

The kinetics was studied for the reactions of ozone with model lignin compounds, viz., phenol, veratrole, veratric aldehyde, and veratric alcohol. Using the mass transfer model for a chemical reaction based on the film theory, the reaction rate constants were calculated. The reaction rate constants determined by both the ozone absorption rate and changes in the substrate concentration coincide satisfactorily, indicating adequacy of the kinetic model chosen. A relationship between the structure of the compounds under study and their reactivity was found.
