Estimating water solubilities of organics as a function of temperature

A simple UNIFAC-based algorithm for estimating the water solubilities of a variety of organics in the temperature range 10–80°C is developed. The procedure covers ten orders of magnitude in solubility with an average deviation of 0.5 log units. The solubilities of ionizable solids are the most sensitive and those of non-ionizable liquids are the least sensitive to temperature change.
