ABSTRACT
With a laser monitoring observation technique, the solubility of ethyl maltol in binary aqueous ethanol solvent mixtures in the temperature range of 293.15 K to 333.15 K was measured by a synthetic method. The solubility data were correlated with the combined nearly ideal binary solvent/Redlich-Kister (CNIBS/ R-K) model. For the nine group data studied, the CNIBS/R-K model was found to provide an accurate mathematical representation of the experimental data.
