Abstract: By using laser monitoring technique, the solubilities of 1,2-cyclohexanediol in different solvents,such as methyl acetate,ethyl acetate,propyl acetate,butyl acetate,methyl acrylate,ethyl acrylate, 2-pentanone,ethyl acetoacetate and water, were measured in larger temperature intervals by the synthetic method.A solubility UNIFAC model was proposed.The model was verified with experimental data in ternary systems of both water + ethyl acetate+1,2-cyclohexanediol and water+butyl acetate+1,2-cyclohexanediol, and the solubilities were calculated by the model and agreed with experimental data.
