Usage

General Description

N-(Phosphonomethyl)glycine diammonium salt, also known as glyphosate, is a widely used herbicide that is non-selective in nature, meaning it can kill a wide variety of plants. It is a systemic herbicide, meaning it is absorbed by the plant and then translocated to all parts of the plant, including the roots. Glyphosate works by inhibiting an enzyme that is essential for plant growth, ultimately leading to the death of the plant. However, there has been controversy surrounding the use of glyphosate, with concerns raised about its potential impact on human health and the environment. Despite this, it remains a popular and commonly used herbicide in the agricultural industry.

METHOD FOR THE SYNTHESIS OF N-(PHOSPHONOMETHYL)GLYCINE

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

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%.
