  • Patent number: 6232494
    Abstract: This invention is directed to an improved process for the preparation of N-(phosphonomethyl)glycine (i.e., “glyphosate”), a salt of N-(phosphonomethyl)glycine, or an ester of N-(phosphonomethyl)glycine. The process comprises combining an N-substituted N-(phosphonomethyl)glycine reactant with oxygen in the presence of a noble metal catalyst. The N-substituted N-(phosphonomethyl)glycine reactant has formula (V): wherein R1 and R2 are independently selected from the group consisting of hydrogen, halogen, —PO3R12R131, —SO3R14, —NO2, hydrocarbyl, and substituted hydrocarbyl other than —CO2R15; and R7, R8, R9, R12, R13, R14, and R15 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, and an agronomically acceptable cation.
    Type: Grant
