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??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??h方程的均方根偏差39.24?10?3.

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.
