【摘要】 采用升温法在 8～ 48℃范围内测定了顺丁烯二酸酐分别在癸二酸二甲酯、癸二酸二乙酯、癸二酸二丁酯和癸二酸二异辛酯的固液平衡数据。分别用经验公式 ,λH方程及Wilson方程对数据进行了关联。Wilson方程能很好地关联数据结果 ,λH方程回归的误差较大。更多还原

【Abstract】 Solid liquid equilibrium data of maleic anhydride in diemethyl sebacate,diethyl sebacate,dibutyl sebacate,and di (2 ethyl hexyl)sebacate were measured by the polythermal method in the temperature range of 8～48 ℃.Empirical formula,λH formula and Wilson equation were used to correlate the data.Wilson equation can correlate the solubility data well,while the deviation is significant in the case of λH equation.
