摘要(Abstract):
目的 :分离乙二醛和醋酸混合溶液中的醋酸 ,纯化乙二醛。方法 :用浑浊法测定体系的分层曲线 ,自动电位滴定仪测定平衡两相中醋酸的含量 ,通过绘制出的三元相图 ,筛选萃取剂。结果 :绘制出了三元相图 ,测定了醋酸的分配系数。结论 :三元体系具有较大的分层曲线 ,醋酸在正辛醇中的分配系数较大 ,正辛醇萃取的醋酸能力较强
Objective:Separate the acetic acid from the mixed solution.Methods: Using the turbidity method and analyzing the acetic acid concentration of both phases at equilibrium.Results:Draw out a ternary system phase chart and determined the distribute coefficient of the cetic acid.Conclution: The selected extractant was efficiency.
