Abstract

A new type of oscillating reaction, the heterogeneous Belousov-Zhabotinskii reaction of oxalic acid, is described. Periodic CO2 and Br2 evolution was measured with the aid of flame ionization and coulometric detectors. The stoichiometry of the reaction was determined and a radical mechanism was proposed based on experiments with acrylamide as a radical scavenger. A possible connection with the mechanism of the original Belousov reaction is mentioned.
