Invention Patent: <B> "PROCESS OF PREPARATION OF AMINO CARBOXYLIC ACIDS, COMPOUNDS AND COMPOSITION" <D>. Process for the preparation of an N-acyl amino carboxylic acid by means of a carboxymethylation reaction. In this reaction a reaction mixture is formed which contains a base pair, carbon monoxide, hydrogen and an aldehyde with the base pair comprising a carbamoyl compound and a carboxymethylation catalyst precursor. In a preferred embodiment, the carbamoyl compound and the aldehyde are selected to give an N-acyl amino carboxylic acid that is easily converted to N- (phosphonomethyl) glycine, or a salt or ester thereof. |
