ABSTRACT:
A method is described for making solution stable salts of iminodiacetic acid (IDA), useful as precursors in the manufacture of N-phosphonomethylglycine. Concentrated dialkali salts of IDA which are insoluble at temperatures below about 55.degree. C., such as the disodium salt (DSIDA) are acidified to monoalkali salts, such as monosodium IDA (MSIDA). The resulting salts are stable in solution, and may conveniently be stored or transported in solution without recourse to dilution, heating, or similar measures.
