Aspects of thermodynamic parameters with a kinetic approach of transition metal catalysed by potassium bromate oxidation of methyl diethylene glycol (MDG) in alkaline medium

Abstract

The kinetic data obtained in ruthenium(VI) catalysed oxidation of methyldiethylene glycol (MDG) in alkaline medium using potassium bromate as oxidant and transition metal ruthenium tetroxide as a homogenous catalyst. In this kinetic reaction, Hg(OAc)2 acts as a liberated bromide ion scavenger. The result shows first order with respect to KBrO3, methyldiethylene glycol (MDG) and transition metal respectively. It shows zero order dependences of the reaction on aqueous sodium hydroxide, which is used as medium of the reaction and also zero effect of mercuric acetate. In this catalysed reaction, ionic strength has positive effect. The corresponding acid was found to be main oxidation product. A plausible reaction mechanism in agreement with kinetic results was put forward.
