Chemical
instabilities during 1,4-naphtodiol oxidation in homogeneous medium. II.
Thermodynamic analysis and mathematical modeling
Abstract
A possible mechanism of the processes of 1,4-naphtodiol
oxidation in oscillatory regime was proposed and a kinetic model was developed.
On the base of analysis of Lyapunov thermodynamic function had been shown that
reasons of the origin of chemical instabilities were the realization of
autocatalytic stages and reversible dynamics bonds. The system of differential
equations describing the kinetics of the reaction were analyzed qualitatively
and solved numerically. The character of the stationary state and the
possibility of bifurcations were examined. The proposed mathematical model
satisfactorily describes the processes occurring in the system.
