Chemical reaction Briggs-Rauscher

The field of oscillating reactions, or periodic reactions, or chemical clocks, came out of this background indeed quite a number of chemical systems have been described, which show this oscillating, periodic, regular behavior (Field, 1972 Briggs and Rauscher, 1973 Shakhashiri, 1985 Noyes, 1989 Pojman etal, 1994 Jimenez-Prieto etal., 1998). 

Briggs and Rauscher discovered an oscillating reaction which is identified as an iodine clock. It resembles the iodate-hydrogen peroxide reaction of Bray (1921), and has some of the elements of the reaction of Belousov, see Section III.C. The chemicals involved are ... 

As more chemists began to study the BZ and Bray reactions, several variants (Orban and Koros,[ 10] Bowers, et al.,[H] ) and hybrids (Briggs and Rauscher, [12]) of these reactions were developed. However, no chemical oscillators with chemistry fundamentally different from that of the two accidentally discovered prototypes were found, and one might summarize the sources of oscillatory reactions prior to I980 as ...
