Solubility Determination and Correlation of (2R,3S,4S,5S)-6-(Hydroxymethyl)-tetrahydro-2H-pyran-2,3,4, 5-tetraol in Fatty Alcohol

(2R,3S,4S,5S)-6-(Hydroxymethyl)-tetrahydro-2H-pyran-2,3,4,5-tetraol (d-glucose) solubility in 1-dodecanol, 1-decanol, and 1-octanol from 343.15 K to 393.15 K was determined, respectively. The solubility of d-glucose increased with an increase in temperature and decreased with the increase of fatty alcohol chain length. The modified UNIQUAC model, S-UNIFAC model, and mS-UNIFAC model were applied to predict the solubility data; the interaction parameters were determined. Of the three models, the modified UNIQUAC model showed better prediction accuracy.
