Mechanism of Ir(III) catalyzed oxidation of glycine by HCF(III) in an alkaline watery media, a kinetics model

Abstract A spectrophotometer has been used to research the rate at which glycine amino acids oxidize by hexacyanoferrate (abbreviated as HCF) III ions in an alkaline watery medium, catalyzed by Iridium (III) chloride and has a steady ionic strength of 0.5 mol dm −3 at a temperature of 35 ± 0.1 °C. First-order rate dependency kinetics were identified to govern the reaction’s progression for [HCF(III)], [OH] − , and [IrCl 3 ]. The rate of reaction decreases as the amino acid concentration rise, according to our findings. Ionic strength of reaction mixture has a beneficial effect on reaction rate. The reaction was observed at four distinct temperatures in order to assess additional activation parameters. Amino acid: HCF (III) = 1:2 is the reaction’s stoichiometry. Glyoxylic acid was discovered as the reaction’s oxidation product using TLC spectroscopy and an organic solvent technique. A suitable mechanism could account for all of the experimental results. It is believed that iridium trichloride and substrate (abbreviated) create a complex as the reaction progresses. To validate the results an established rate law is used.
