Abstract The instabilities of the Belousov-Zhabotinskii reaction were studied in an isothermal CSTR by varying the space velocity as bifurcation parameter. The time-dependent concentration of bromide ion and redox potential were observed, respectively, by a Ag-AgBr electrode and a platinum-wire electrode under reaction-controlling conditions. The single-peak periodic and the chaotic oscillations occur alternately with increasing space velocity. The multipeak oscillations were also observed at higher space velocities. Two kinds of chaotic oscillations were observed, chaotic oscillations with amplitudes varying irregularly in the periodic-chaotic sequence region and chaotic mixing of large and small amplitude in the multipeak oscillations region. An analysis of the phase portraits for these chaotic oscillations indicates that they correspond to low dimensional and fractal structures.
