The modified Belousov-Zhabotinskii oscillation reaction with ethyl ester of 3-oxobutanoic acid is remarkable in that it does not yield carbon dioxide and the reaction system is closed and homogeneous until an emulsion of a bromo derivative of the substrate appears. As long as the system is homogeneous, it oscillates even in the motionless state and its oscillation behaviour in the absence of oxygen is independent of the intensity of stirring. The results obtained by polarography with a rotating platinum electrode are in agreement with those obtained by spectrophotometry.
