Process for the preparation of N-phosphonomethylglycine |
| abstract |
The invention relates to a process for the preparation of N-phosphonomethylglycine of the formula I ##STR1## wherein a compound of the formula II or salts and esters thereof ##STR2## in which R 1 and R 2 denote hydroxyl or a hydrolyzable group and R 3 denotes aryl, is reacted in a closed reaction vessel in the presence of a dehydrogenation catalyst and a hydrogenation catalyst with an alkali metal hydroxide or alkaline earth metal hydroxide in water as the solvent and, when the reaction has ended, a mineral acid is added to liberate N-phosponomethylglycine from its salt. |
