WebMay 1, 2010 · The malonic acid (MA)-based oscillating Briggs–Rauscher reaction (BR) in batch mode has been shown to be sensitive to various hydrophilic polyphenol antioxidants. Several of these have been shown to cause cessation of oscillations for a period of time before a restart occurs. The length of time before oscillations restart is related to the type … Websystem must be slower than the reactions of the constituents of the system with each other. The oscillation is seen as the peri odic depletion of the reactants and surge of products. The existence ofbistability is an interesting aspect in the occurrence of oscillations.
