从水溶液中提取琥珀酸

Extraction of Succinic Acid from Aqueous Solution

琥珀酸是一种用途广泛的有机酸，但现有的制备过程工艺复杂、成本较高。本文提出了一个有效的萃取体系，用以提取废液和稀溶液中的琥珀酸。并对其萃取体系及其萃取机理进行了较为全面的研究，进而提出了一个从水溶液中提取琥珀酸的建议流程。

In order to recover succinic acid from aqueous solution, several extractants for the extraction of succinic acid were examined practically. It was found that the phosphorus-bonded oxygen-donor extractants TBP was the most effective and economical one in these extractants. For practical application, many factors affecting the extraction and stripping were considered, a new process of recovering succinic acid from aqueous solution was proposed.
