摘　　要：The solvent extraction method was used to obtain trans-1,2-cyclohexanediol in the synthesis from cyclohexene and hydrogen peroxide.On the basis of the phase equilibrium for trans-1,2-cyclohehanediol in methyl acetate,by using the laser monitoring technique,the solubilities of trans-1,2-cyclohexanediol in methyl acetate and water mixed solvent were measured in a larger temperature interval.A solubility UNIFAC model was proposed.The model was verified with experimental data in ternary systems of water+methyl acetate+trans-1,2-cyclohexanediol,and the solubilities calculated with the model were in good agreement with experimental data.The solvent extraction method was used to obtain trans-1, 2-cyclohexanediol in the synthesis from cyclohexene and hydrogen peroxide.
