Process to prepare a chelating agent or precursor thereof using a cyanide salt |
| abstract |
The present invention relates to a process comprising the reaction of a cyanide with an amino acid and an aldehyde, characterized in that the cyanide is a cyanide salt, the amino acid is aspartic acid and/or glutamic acid in the acidic form, and the process is performed under acidic pH by the addition of between 0 and 1 equivalent of an acid based on the amount of aspartic or glutamic acid. |
