Kinetics and mechanism of Ir (III) catalysed oxidation of DMannose by acidic solutions of potassium per manganate
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 11
Abstract
The oxidation of D- Mannose with permanganate ion ( MnO4 - ) as oxidant was observed in acidic medium by visible spectrophotometric method in the temperature range (300 – 320) K. The reaction exihibit pseudo first oder kinetics with respect to change in concentration of D- Mannose, MNO4- and H+ followed by the change in absorbance of oxidant at 546 nm. Negligible effect of ionic strength ( μ ) on the rate of oxidation has also be noted which supports the presence of at least one neutral species in the rate determining step. The various activstion parameters have been calculated. A suitable mechanism consistent with experimental finding has been proposed.
