Solid-Liquid Equilibria of trans-1,2-Cyclohexanediol+Butyl Acetate+ Water Ternary System1 1 Supported by the Natural Science Foundation of Henan Province (No.0211020800).

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 calculated values is 3.03%.
