Chlorine dioxide-iodine-malonic acid CDIMA reaction

The Lengyel-Epstein model is a more realistic chemical reaction scheme. The Lengyel-Epstein model is a two-variable model for the chlorite-iodide-malonic acid (CIMA) reaction scheme and its variant, the chlorine dioxide-iodine-malonic acid (CDIMA) reaction scheme. In the model, the oscillatory behavior is related with ... 

The Chlorite-Iodide-Malonic Acid (CIMA) and Chlorine Dioxide-Iodine-Malonic Acid (CDIMA) Reactions... 

Dividing blobs, chemical flowers and patterned islands Different modes of propagation of the patterned state have been observed in CDIMA reaction (chlorine dioxide-iodine-malonic acid - PVA in a one-sided-fed reactor) in an absolutely unstable uniform state, among which are a spot division and finger printing mode [55]. 

Historically, it was the CIMA reaction in which Turing patterns were first found. Under the conditions of these experiments, however, our analysis suggests that, after a relatively brief initial period, it is really the CDIMA reaction that governs the formation of the patterns. Even when the input feeds consist of chlorite and iodide, chlorine dioxide and iodine soon build up within the gel and play the role of reactants whose concentrations vary relatively slowly compared with those of C102 and I . We have therefore found it more practical to work with the CDIMA system, using chlorine dioxide and iodine along with malonic acid as the input species, since in this way the relevant parameters can more easily be measured and controlled. Working with the CDIMA system also leads us naturally toward a simpler version of the model described by eqs. (14.22)-( 14.24).
