The Jiangsu Good Harvest Wayne Agrochemical Co., Ltd. has successfully developed high-purity glyphosate (≥98%) and has realized industrialization using a new process.
The process route adopts the internationally advanced IDA method to synthesize glyphosate, using iminodiacetonitrile as the starting material, and obtaining IDA through hydrolysis, neutralization, and acidification processes, and IDA is condensed with formaldehyde, phosphonous acid, etc. to generate N -Phosphonomethyliminodiacetic acid (bis-glyphosate), which reacts with oxygen in the air under specific catalysts to produce glyphosate. The purity of this process product can reach more than 98%, the quality exceeds the foreign standard, and reaches the international advanced level.
The good harvest company uses air oxidation instead of hydrogen peroxide oxidation technology and uses a new process to synthesize glyphosate, which not only saves a lot of chemical raw materials, but also improves the reaction efficiency and the yield of solid glyphosate. At present, the company's high-purity glyphosate has been exported to Europe and the United States.
