<p>Process for preparing N-phosphonomethyl glycine by wet oxidation of N-(phosphonomethyl)iminodiacetic acid with an oxygen enriched air or with hydrogen peroxide at pressures of 100 - 1000 bar, at temperatures of 50 - 500 DEG C, and reaction times of 0.01 - 10 hours. The process may be performed at subcritical, or preferably supercritical conditions of wet oxidation of N-(phosphonomethyl)iminodiacetic acid. The process is preferably continuous. N-phosphonomethyl glycine, known under the generic name glyphosate, in an active substance indicated for the use in ecologically appropriate herbicides.</p> |
