Malic and succinic acids are an important C4 dicarboxylic acid and they are widely used in food, cosmetics, products and textile industry. There are many reports about the effort to produce the malic and succinic acids using the biological method instead of petrochemical-based process. In recent years, reactive extraction processes have been received as an
increasing attention for recovery of carboxylic acids from aqueous solution. Reactive extraction is the separation process using reaction between extractants and materials extracted. The extractant in the organic phase reacts with material of aqueous phase and reaction complex formed was solubilized into the organic phase. In this study, the extraction equilibrium of malic and succinic acids with TOA/1-octanol was investigated. And extraction characteristics of solutions containing malic and succinic acids with effcet of pH were studied. The compositions of malic and succinic acids with a gram ratio of malic acid to succinic acid of 13.6:1 based on the fermentation results by Taing, O. and Taing, K.1)
