Purity Standards and Quality Requirements

National Standards

1.According to GB/T 12686-2017 Glyphosate Technical Material, the purity of glyphosate technical material shall be ≥95.0%, with strict limits on impurities: formaldehyde ≤1.2g/kg, nitrosoglyphosate ≤1.0mg/kg, and water-insoluble substances ≤0.2g/kg.
2.The purity of industrial-grade glyphosate acid is usually 95%, while reagent-grade products can reach higher purity (e.g., 98%). For example, a 95% glyphosate acid product provided by a supplier clearly specifies that water-insoluble substances ≤0.2%, which is suitable for agricultural weeding.

Production Processes and Technologies

Main Synthesis Methods

1.IDA process (Iminodiacetic acid process): Using iminodiacetic acid (IDA) as raw material, glyphosate acid is produced through catalytic oxidation reaction. This process has few by-products and high yield, making it the current mainstream route.
2.Glycine process: Using glycine, formaldehyde, and phosphorous acid as raw materials, glyphosate acid is prepared through condensation and hydrolysis. Some enterprises have shortened the reaction time and increased output by optimizing the hydrolysis process (e.g., thin-film heating technology).

Impurity Control Technologies

1.Patented technologies selectively remove impurities such as formaldehyde through oxidation with carbon catalysts (containing metals like Mn and Fe) and oxygen, ensuring product stability.
2.The reaction mother liquor is recycled 5-6 times to reduce energy consumption and improve the yield of glyphosate acid.

Application Fields and Market Demand

Agricultural and Industrial Weeding

95% glyphosate acid is the core component of broad-spectrum non-selective herbicides, widely used in orchards, tea gardens, rubber plantations, and non-cultivated land for weeding. It can control annual and perennial weeds such as Cyperus rotundus and Cynodon dactylon. Its mechanism of action is to inhibit the EPSPS enzyme in plants, blocking the synthesis of aromatic amino acids.

Formulation Processing

Glyphosate acid needs to be converted into water-soluble salts (such as isopropylamine salt and ammonium salt) for effective use. For example, 41% glyphosate isopropylamine aqueous solution is one of the global mainstream formulations.
