Process for producing a product N - (PHOSPHONOMETHYL) glycine; Process for removing water from an aqueous solution of departure and continuous process for catalytic oxidation of a substrate N - (PHOSPHONOMETHYL) iminodiacetic acid to produce a product N - (PHOSPHONOMETHYL) glycine

摘要

Oxidation in Liquid Phase for producing N - (PHOSPHONOMETHYL) glycine (also known as glyphosate in the Agrochemical Industry) and related compounds.It also describes in particular processes in which oxidizes a substrate iminodiacu00e9tico acid n - (PHOSPHONOMETHYL) into a product of N - (PHOSPHONOMETHYL) glycine, which in turn is CRYSTALLIZED (at least in part) in an Adiabatic Crystallizer.Claim 1: a process to develop a product N - (PHOSPHONOMETHYL) glycineCharacterized in that it comprises: Introducing an aqueous feed stream that comprises a substrate of acid n - (PHOSPHONOMETHYL) iminodiacu00e9tico within a reactor System oxidation; oxidize the substrate iminodiacu00e9tico acid n - (PHOSPHONOMETHYL) in the system of oxidation reactor in PR. To an Oxidation Catalyst to produce a solution of the reaction product contains a proDUCT (PHOSPHONOMETHYL) glycine; precipitate Crystals of Product N - (PHOSPHONOMETHYL glycine), the solution of the reaction product to produce a Slurry comprising Primary product Crystals Precipitated Product N - (PHOSPHONOMETHYL glycine) and a primary Mother Liquor; and evaporate the water L Primary Mother Liquor.Consequently Crystals precipitating additional Product N - (PHOSPHONOMETHYL glycine) and producing a secondary Mother Liquor.
