| titleOfInvention | The novel process of preparing glyphosate by glycin method |
| abstract | The present invention relates to the novel process of preparing glyphosate by glycin method, comprise the following steps: glycine, polyoxymethylene, under the effect of catalyzer KOH, addition reaction occur, generate N, N-dihydroxymethyl glycine, solvent is methyl alcohol; N, N-dihydroxymethyl glycine and dimethylphosphite polymerization reaction take place, generate glyphosate methyl esters; Thereafter add hydrochloric acid in reaction solution and carry out acidolysis, generate glyphosate and methylal; Then the de-acidic methanol of distillation, at 115 DEG C, decompression depickling, last suction filtration crystallization, solid is glyphosate, and mother liquor is sodium chloride-containing not, and major ingredient is glyphosate and glyphosate potassium, can do Potassium Fertilizer, pollution-free; Shorten process cycle, reduce manpower and materials and drop into, increase economic efficiency, energy-conserving and environment-protective. |
