METHOD FOR THE SYNTHESIS OF N-(PHOSPHONOMETHYL)GLYCINE
-
Paragraph 0131, (2014/02/15)
The present invention is related to a method for the synthesis of N- (phosphonomethyl)glycine or one of its derivatives selected from the group consisting of its salts, its phosphonate esters, or its phosphonate ester salts, which includes the steps of: ? a) forming, in the presence an acid catalyst, a reaction mixture comprising 2,5- diketopiperazine, formaldehyde and a compound comprising one or more P-0-P anhydride moieties, said moieties having one P atom at the oxidation state (+ III) and the other P atom at the oxidation state (+III) or (+V), to form Ν,Ν'- bisphosphonomethyl-2,5-diketopiperazine, its mono- to tetra phosphonate esters, the dehydrated forms of Ν,Ν'- bisphosphonomethyl-2,5-diketopiperazine and the phosphonate esters of its dehydrated forms; ? b) hydrolysing said N,N'-bisphosphonomethyl-2,5-diketopiperazine, its dehydrated forms or their phosphonate esters to obtain N- (phosphonomethyl)glycine or one of its derivatives selected from the group consisting of its salts, its phosphonate esters and its phosphonate ester salts.
Process for Preparing Ammonic Glyphosate Granules
-
Page/Page column 3-5, (2008/12/07)
A process for preparing water-soluble granules of amnionic glyphosate comprising: a) addition of glyphosate acid to a Broensted base which supplies ammonium ions in a molar ratio base/acid comprised between 0.8 and 1.1; b) homogenization of the mixture prepared in a); c) addition of one or more surfactants in amounts in the range 5%-50% by weight based on the glyphosate acid; d) mixing of the mass prepared in c) for a time lower than about 10 minutes until obtaining an extrudable mass; e) extrusion of the mass obtained in d); f) drying until obtaining a granule having a residual moisture lower than 1%.

-
Page 2, (2008/06/13)
A solid herbicidal formulation of N-(phosphonometyl)glycine is described, in powder, granule, or flake form, soluble or dispersible in water, is described, containing Glyphosate (N-(phosphonomethyl)glycine) in the form of hydrosoluble salt and also including 5% to 30% in weiglit of one or more tensioactive agents, soluble in water, compatible with glyphosate and which are solid at ambient temperature, i.e. at approximately 25° C. The process for preparation of said herbicidal formulation is also described.
