実験手順

50 g (0.3 moles) of N-(phosphonomethyl)-glycine are reacted with 17.5 g (0.3 moles) of isopropylamine in 200 ml of 96% ethanol at room temperature. The mixture is refluxed for half an hour, filtered, concentrated by evaporation and crystallized. 69 g (0.3 moles) of crystalline, dried mono-isopropylammonium salt of N-(phosphonomethyl)-glycine are obtained. The product is not hygroscopic, readily soluble in water. Melting range 161°-163° C. It contains 73.9% N-(phosphonomethyl)-glycine Yield 99.95%. Characteristic absorption bands (FT-IR spectroscopy, cm-1) 1660, 1600, 1553, 1545, 1075, 513, 475, characteristic values of crystal-lattice-planes measured with X-ray diffraction: 11.0, 9.06, 5.94, 5.54, 4.13, 3.71. (α type crystals).
