By numerical calculations based on our previously proposed model with Br2O intermediate species we were able to simulate complex evolution of the Belousov-Zhabotinsky (BZ) reaction under batch conditions. In the defined region of initial malonic acid concentration [MA](0) (1.00 x 10(-3) mol dm(3) a parts per thousand currency sign [MA](0) a parts per thousand currency sign 1.50 mol dm(-3)) different sequences of regular and complex periodic and aperiodic oscillations were obtained. It is noticed that the bromine evaporation significantly affects the dynamics of the reaction.
