摘要 |
This invention is directed to process for making a composition having the formula (I): wherein R3, R4, and R5 are independently hydrogen, substituted or unsubstituted hydrocarbyl, or an agronomically acceptable cation. The process comprises contacting a solution with a noble metal catalyst and introducing oxygen into the solution. The solution contains an N-substituted glyphosate having the formula (II): wherein R1 and R2 are independently hydrogen, halogen, -PO3H2, -SO3H, -NO2, or substituted or unsubstituted hydrocarbyl other than -CO2H. R3, R4, and R5 are as defined for formula (I). This invention also relates to an oxidation catalyst comprising a noble metal having a hydrophobic electroactive molecular species adsorbed thereon.
