Description

Technical Field

[0001] The invention relates to the technical field of glyphosate aqueous solution production, in particular to liquid separation and recovery equipment for glyphosate aqueous solution production. Background Art

[0002] Glyphosate uses dimethyl phosphite to react with formaldehyde and glycine to generate glyphosate dimethyl ester, which is then hydrolyzed to obtain glyphosate. This method has the advantages of high efficiency and high purity, and is currently the main method for producing glyphosate. The use of glyphosate Glyphosate is an organophosphorus herbicide, which is widely used in agriculture, forestry, animal husbandry and other aspects, including forests, rubber plantations, farmlands, tea mulberry, orchards, sugarcane fields, border defense roads, forest fire isolation belts, as well as railways, airport warehouses, oil depots, power stations and other non-agricultural weed control.

[0003] In the prior art, glyphosate is slightly soluble in water and has a density of 1.74 g / cm 3 Therefore, when glyphosate is prepared, the glyphosate solution is mixed with other substances insoluble in water.
