A continuous stirred tank reactor for propylene glycol production is shown in this paper, analyzing the regular, self-oscillating and chaotic dynamics, which can appear under specific operating conditions. The paper shows that there is a small interval of concentration and temperature of the inlet stream to the reactor, that produces self-oscillating behavior, taking into account the variation of eigenvalues of the linearized system at the equilibrium point, both the multi-dimensional and two-dimensional simplified models of the reactor. The conditions that produce chaotic dynamics are researched when the reactor is in self-oscillating regime, showing that a coolant flow rate periodic variation can produce chaotic behavior. Through the determination of chaotic maps, bifurcation diagrams, the existence of a new set of strange attractors has been tested, showing that the mechanism of chaos is due to the transition from quasi-periodic initial state. A short explanation of the simulation programs is also presented.
