| 초록 | The extraction of organic acids from aqueous media and other broth has been investigated in connection with the development of the biotechnology in the last decade. The efficient separation of organic acids from aqueous solutions is of economic importance in the chemical industry, for example in the fermentation industry. Solvent extraction processes as a promising recovery technique have been proposed as an alternative to the conventional precipitation process, and many solvents have been tried to improve such recovery. The purpose of this work is to determine LLE data of o-xylene + water + butyric acid +1-butanol and the LLE data for the quaternary system were measured at 25℃ under atmospheric pressure. The effect of the mixed solvents to separate butyric acid from aqueous solution was investigated. LLE data have also been predicted with the UNIFAC method, and they are compared with the experimental data at 25℃. |
