Versuchsvorschrift
Reaction of glycine and formylphosphonic acid was carried out under the conditions of Example 2 except that the pH was initially adjusted to 8.0 and hydrogen gas was continuously bubbled through the liquid phase at atmospheric pressure. After 18 hours of reaction, a 65.9% yield of glyphosate was obtained.
