نظرة عامة

Glyphosate (N-(phosphonomethyl)glycine) is the most widely used herbicide globally, originally developed and marketed by Monsanto as Roundup. It works by inhibiting the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in the shikimate pathway, which is essential for aromatic amino acid synthesis in plants but absent in animals. Glyphosate's use expanded dramatically with the introduction of genetically modified glyphosate-resistant crops (Roundup Ready) in 1996. The herbicide went off patent in 2000, and China now produces over 60% of global supply.

العملية الكيميائية

The predominant industrial route (IDA pathway) reacts iminodiacetic acid (IDA) with formaldehyde and phosphorous acid. IDA is produced from glycine and formaldehyde via a Strecker-like reaction, then phosphonomethylated. Alternatively, the glycine route (Monsanto process) uses DEPA (diethyl phosphite), formaldehyde, and glycine. The product is purified and formulated as the isopropylamine salt (IPA) for liquid products.

HN(CH2COOH)2 + HCHO + H3PO3 ->[catalyst] (HOOC-CH2)N(CH2PO(OH)2)(CH2COOH) -> HOOC-CH2-NH-CH2-PO(OH)2 + HCOOH (IDA route, oxidative decarboxylation)

المواد الخام

  • Iminodiacetic acid (IDA, HN(CH2COOH)2) — Reaction of glycine with formaldehyde and HCN (Amine backbone)
  • Phosphorous acid (H3PO3) — Hydrolysis of phosphorus trichloride (Phosphorus source)
  • Formaldehyde (HCHO) — Methanol oxidation (Methylenating agent)

المنتجات النهائية

  • Glyphosate IPA salt (C3H8NO5P) — Non-selective systemic herbicide (Formulated as 360-480 g/L aqueous concentrate)

Environmental Impact

Glyphosate degrades in soil with a half-life of 2-215 days (median ~47 days) primarily through microbial metabolism. AMPA (aminomethylphosphonic acid) is the primary degradation product. Glyphosate has been classified as 'probably carcinogenic' (IARC Group 2A) though regulatory agencies (EPA, EFSA) have generally concluded it is unlikely to be carcinogenic at typical exposure levels. The debate remains highly contentious.
