摘要
通过对萃取剂的筛选，确定了一个以三烷基氧化磷（ＴＲＰＯ）为萃取剂，提取富马酸（ＦＡ）的萃取体系。采用双对数法，红外图谱和水分分析对萃合物的研究表明：ＴＲＰＯ萃取ＦＡ的可能萃合物结构式为ＦＡ·２ＴＲＰＯ·Ｈ２Ｏ。对萃取过程中的各影响因素进行了考察，从而得到了最佳操作条件，并提出了一条采用溶剂萃取法从水溶液中提取ＦＡ的流程。
In order to recover fumaric acid from aqueous solution, severalextractants for the extraction of fumaric acid were examinedpractically. It was found that the phosphorus-bonded oxygen-donorextractant TRPO was the most effective and economical one in the seextractants.For practical application, many factors affecting the extraction and stripping were considered, a new process of recovering fumaric acid from aqueous solution was proposed.
