Abstract

Solubility of 4,4?-dihydroxydiphenylsulfone in ethyl acetate?benzene mixture solvents was measured using the ways of laser-assisted quality system of 283.15~333.15 K. The results showed that solubility of 4,4'-dihydroxydiphenylsulfone in the mixture solvent decrease with the increase of benzene mole fraction in solvents and increase significantly with the rise of temperature. Modified Apelblat equation and ??h equation were used in data regression and the average root-mean-square deviation are 19.86?10?3, 39.24?10?3 respectively, modified Apelblat equation provides better fitting result.

Key words： 4,4?-dihydroxydiphenylsulfone; solubility; mixture solvents; quality laws
