摘要: Using a laser observation technique, the solubilities of trans-1,2-cyclohexanediol in butyl
acetate + water were measured at the temperature range from 298.15K to 323.15K by a
synthetic method at atmospheric pressure. It is shown that the solubilities of trans-1,2-
cyclohexanediol in butyl acetate + water were affected greatly by the proportion of butyl
acetate and water, and presented maximum value at given temperature. The UNIFAC model was
used to correlate the experimental data. The average relative deviation (ARD) between
experimental and cal-culated values is 3.03%.
