Arsenous Acid Oxidation Investigated in Micro Reactors

3 Arsenous Acid Oxidation Investigated in Micro Reactors Organic synthesis 92 [OS 92] Oxidation of arsenous acid by iodate [Pg.560]

The arsenous acid-iodate reaction is a combination of the Dushman and Roebuck reactions [145]. These reactions compete for iodine and iodide as intermediate products. A complete mathematical description has to include 14 species in the electrolyte, seven partial differential equations, six algebraic equations for acid-base equilibriums and one linear equation for the local electroneutrality. [Pg.560]

This reaction undergoes conversion in one sequence of consecutive elementary reaction steps and so only one propagating front is formed in a spatially distributed system [68]. Depending on the initial ratio of reactants, iodine as colored and iodide as uncolored product, or both, are formed [145]. [Pg.560]
