ABSTRACT
The solubilities of N-(phosphonomethyl)iminodiacetic acid in water, ethanol + water, propan-1-ol + water, and propan-2-ol + water were measured in the temperature range from (293 to 333) K at atmospheric pressure. A laser monitoring observation technique was used to determine the dissolution process. A semiempirical equation was found to provide an accurate mathematical representation of the experimental data.
