A novel, non-halogen-based chemical oscillator

Description
Summary:Although a kinetic bistability in the reduction of permanganate by hydrogen peroxide 1 as well as in the reduction of permanganate by oxalate 2,3 in a continuous-flow tank reactor (CTR) has recently been observed, a permanganate chemical oscillator has not yet been described. So far, the only oscillator known has been a bromate one containing permanganate, Mn 2+ ions and oxalate as a subtrate 4 . The discovery of new chemical oscillators which are essentially different from those described previously is of great importance, as it supplies further information concerning the exact mechanistic requirements for chemical oscillations to occur. We report here the conditions under which a permanganate chemical oscillator functions in a CTR.
