Recovery of Glutaric acid by Reactive Extraction using Tri-n-Octylamine in Different Biodiesels

This paper is aimed to recover Glutaric acid from aqueous solution by using Tri-n-Octyl amine in different biodieselsthrough an experimental investigation by reactive extraction. Here Glutaric is extracted by reversible complexion reaction with tri-n-octylamine extractant present in three types of biodiesel- sunflower, sesame and rice bran. The distribution coefficients (KD) for experimental investigation system comes out to be (9.38-25.37) for sunflower biodiesel, (9.61-30.88) for sesame biodiesel and (10.62-29.92) rice bran diesel. The determined loading ratios (Ø) were in the range (0.27-4.05) for sunflower biodiesel, (0.27-4.02) for sesame biodiesel and (0.27-4.05) rice bran biodiesel, indicating overloading of the extractant. A very high average extraction efficiency (%E) is in the range of (90.36-96.20) for sunflower biodiesel, (90.57-96.86) for sesame biodiesel and (91.40-96.30) rice bran biodiesel) were obtained in the present investigation.
