Product 1

HCID 3496GlyphosateYield 96.2%

Procedure

According to the process of the invention totally 790 g (3.48 mole) of N-phosphonomethyl-imino diacetic acid, 70 g of sulphuric acid and 1044 g of 34g (10.44 mole) hydrogen peroxide were used. 320 g of sulphuric acidic waste crystallisation mother liquor solution, 440.2 g (2.51 mole) of 96.2% N-phosphonomethyl-glycine were formed, corresponding to a yield of 72.0%. Boiling point: 203° C.
