The solubilities of xylitol in binary ethanol + acetone solvent mixtures were measured using a laser technique with the temperature range from 293 K to 323 K at atmospheric pressure. Results of these measurements were correlated by the combined nearly ideal binary solvent (CNIBS)/Redlich-Kister equation. The experimental solubility and correlation equation in this work can be used as essential data and as a model in the purification process of xylitol.
