METHOD FOR PRODUCING N-(PHOSPHONOMETHYL)-GLYCINE Russian patent published in 2017 - IPC C07F9/38

Abstract RU 2618629 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a process of preparation used in agriculture N-(phosphonomethyl)-glycine (glyphosate). In the proposed method of N-(phosphonomethyl) - iminodiaceticacid is subjected to catalytic liquid phase oxidation of an aqueous solution of hydrogen peroxide in a two phase system (organic phase - the aqueous phase) in the presence of a metal complex catalyst having general formula Q₃{PO₄[W(O)(O₂)₂]₄}, where Q - a quaternary ammonium cation - [(R₁)₃NR₂]⁺, where R₁, R₂ contain from 1 to 16 carbon atoms.

EFFECT: high yield of glyphosate with a considerable simplification of the process.
