Publication number: 20090259068Abstract: This invention generally relates to liquid phase oxidation processes for making N-(phosphonomethyl)glycine (also known in the agricultural chemical industry as glyphosate) and related compounds. This invention, for example, particularly relates to processes wherein an N-(phosphonomethyl)iminodiacetic acid (NPMIDA) substrate (i.e., N-(phosphonomethyl)iminodiacetic acid, a salt of N-(phosphonomethyl)iminodiacetic acid, or an ester of N-(phosphonomethyl)iminodiacetic acid) is continuously oxidized to form an N-(phosphonomethyl)glycine product (i.e., N-(phosphonomethyl)glycine, a salt of N-(phosphonomethyl)glycine, or an ester of N-(phosphonomethyl)glycine). This invention also, for example, particularly relates to processes wherein an N-(phosphonomethyl)iminodiacetic acid substrate is oxidized to form an N-(phosphonomethyl)glycine product, which, in turn, is crystallized (at least in part) in an adiabatic crystallizer.Type: ApplicationFiled: February 4, 2009Publication date: October 15, 2009Applicant: MONSANTO TECHNOLOGY LLCInventors: Eric Haupfear, Jerald D.

Publication number: 20050159305Abstract: This invention is directed to a process for making a salt of a carboxylic acid. The process comprises contacting a catalyst with an alkaline mixture comprising a primary alcohol. In one embodiment, for example, the catalyst comprises a metal support (preferably a metal sponge support) having a copper-containing active phase at the surface thereof. The support is resistant to deformation under the conditions of the dehydrogenation reaction. In another embodiment, the catalyst comprises a metal sponge having a copper-containing active phase at the surface thereof and a supporting structure containing at least 10% non-copper metal. This invention is also directed to copper-containing catalysts which may, for example, be used in the above process. This invention is further directed to processes for making such catalysts.Type: ApplicationFiled: January 4, 2005Publication date: July 21, 2005Applicant: Monsanto CompanyInventors: David Morgenstern, Juan Arhancet, Howard Berk, William Moench, James Peterson
