Glutaric acid produced by biological methods is contained in water based systems with various impurities. Herein, counter-current multistage extraction was investigated using 2-butanone for the effective and economical recovery of glutaric acid from the water based systems. 7-stage consecutive extraction was carried out at the mass ratio between aqueous phase(water based system) and solvent phase(2-butanone) of 1:1 and 2:1. In the 7-stage extraction, most of the glutaric acid could be recovered from the aqueous phase, but colourful dye components were extracted simultaneously. In order to increase the purity of glutaric acid, back extraction was performed using water with a mass ratio of 0.5 but the dye components could not be completely removed. |
