摘要
采用综合法测定了顺丁烯二酸酐 (顺酐 )在己二酸二乙酯 ,丙二酸二乙酯 ,丁二酸二乙酯 ,癸二酸二乙酯的固液平衡数据 ,并与顺酐在六氢化邻苯二甲酸二异丁酯中的溶解性进行了比较 ,发现该类溶剂为很好的顺酐溶剂。采用经验公式、λH方程、Wilson方程对顺酐在直链二酸二乙酯中的溶解度数据进行了关联 ,Wilson方程能很好地关联数据。
Solid liquid equilibrium data of maleic anhydride in diethyl adipate,diethyl malonate,diethyl succinate,diethyl sebacate were experimentally determined by means of polythermal method,and experimental data were compared with solubility data of maleic anhydride in 1,2 cyclohexanedicarboxylic acid diisobutyl ester.Chain dicarboxylic acid diesters are suitable for recovering maleic anhydride.Experienced equation,λ H equation and Wilson equation were used to correlate data.Wilson equation can correlate the solubility data well.
