| Abstract: | A method of solvent extraction for extracting and separating itaconic acid was developed. At first, the suitable extractants were chosen. Then, the effects of several technological parameters, the concentration of itaconic acid and pH value in aqueous phase, concentration of extractant in organic phase and temperature on extraction of itaconic acid were determined. Based on the experimental results a mathematic model was developed. |

| Keywords: | itaconic acid solvent extraction trialkyl phosphine oxide(TRPO) tributyl phosphate(TBP) trialkyl amine(N 235 ) |
