Abstract
N-Substd. iminodiacetic acids of formula (I) are new (R = hydroxyalkyl other than hydroxyethyl or 3-hydroxypropyl; alkoxyalkyl or dihydroxyalkyl in which the OH gps. are attached to non-adjacent C atoms). (I) are chelating and sequestering agents esp. useful for improving water quality. They are non-toxic and are superior to known polycarboxylic acids. (II) are used to eliminate kidney stones either by direct infusion into the kidney or by oral application; they even dissolve stones based on Ca oxalate.
