Kinetics of N-Phosphonomethyl Iminodiacetic Acid Catalytic Oxidation with Hydrogen Peroxide Under the Phase-Transfer Conditions

Oxidation of the N–phosphonomethyl iminodiacetic acid (PMIDA) with hydrogen peroxide in a two-phase system (aqueous phase—organic phase) in the presence of the [(Oct n ) 3 NMe] 3 {PO 4 [WO(O 2 ) 2 ] 4 } catalyst was studied and the kinetic parameters of this reaction were determined. It was found th...

Description
Summary:Oxidation of the N–phosphonomethyl iminodiacetic acid (PMIDA) with hydrogen peroxide in a two-phase system (aqueous phase—organic phase) in the presence of the [(Oct n ) 3 NMe] 3 {PO 4 [WO(O 2 ) 2 ] 4 } catalyst was studied and the kinetic parameters of this reaction were determined. It was found that the PMIDA oxidation with aqueous H 2 O 2 proceeds only in the presence of the catalyst giving PMIDA N-oxide as the main product. Under the studied conditions, the reaction orders with respect to the reagents (PMIDA and H 2 O 2 ) and the catalyst were found to be the first. The apparent activation energy of the reaction for the temperature range of 313–343 K is 37 ± 3 kJ/mol. Graphic Abstract
