Ammonia → Iminodiacetic acid

Participants

Reaction Steps

Using the apparatus and procedure of Example 6, two runs were carried out in which glyoxal was reacted with sulfur dioxide and ammonia. In the first run, one equivalent of sulfur dioxide and one equivalent of glyoxal were charged per mole of ammonia. In the second run, two moles of glyoxal and two moles of sulfur dioxide were charged per mole of ammonia. In each run a mixture of glycine and iminodiacetic acid was produced. The results of the runs of this example are set forth in Table III.
