摘　　要：采用激光辅助质量法测定了283.15~333.15 K下4,4'-二羟基二苯砜在乙酸乙酯-苯混合溶液中的溶解度.结果表明,4,4′-二羟基二苯砜的溶解度随混合溶液中苯摩尔分数增加而下降,随温度升高显著增加.用改进的Apelblat经验方程和λ-h方程关联溶解度数据,改进的Apelblat经验方程的均方根偏差为19.86×10^(-3),优于λ-h方程的均方根偏差39.24×10^(-3).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 2-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.
