The overall purpose for this research project is to establish nonionic surfactants as a replacement to traditional solvents. Surfactants offer the opportunity to bring reactants of differing polarity in close proximity. Many nonionic surfactants are liquid at room temperature, are non-hazardous, biodegradable, and inexpensively available as raw material. In addition, we noticed significant solubility of mineral salts in nonionic surfactants, which could be advantageous for organic synthesis. Therefore, we determined the solubility of potassium halide salts in three different nonionic surfactants using atomic absorption spectrophotometry. The salt solubility of the potassium halide salts decreased from on the order of 10 mol*kg-1 at the highest water mass fraction of 0.8 to about 0.01 mol*kg-1 at the least water mass fraction of 0.015. It was found that the solubility in the least water content surfactant solution is in the order KCl < KBr < KI.
