Mechanism of Ru (III) catalysis in acid bromate oxidation of dimethyl diethylene glycols: A kinetic study

摘要

Ru(III) catalyzed Oxidation of dimethyl diethylene glycol (DMDG) by potassium bromate in acidic media in the presence of mercuric acetate shows zero order dependence on dimethyl diethylene glycol [H+] ions while it is first order for [bromate] and Ru(III). Addition of mercuric acetate has no effect on the reaction. The real reactive species of Ru (III) chloride has been proposed as (RuCl2(H2O)4]+ in the acid range. The reaction product is the corresponding aldehyde. Various activation parameters have been computed.
