The solubility of methyl paraben in various amide-water mixtures was measured at 25.0 degrees Centigrade. The paraben solubility increases exponentially above an amide concentration corresponding to the point at which the amide apparent molar volume passes through a minimum. A model for the observed phenomena was proposed on the basis of data from solvent systems which included sixteen amides and various of their aqueous mixtures. The model proposes the formation of amide aggregates. The research was done to provide information on the effects that a stream's normal organic content will have upon the solubility of organic water pollutants.
