Abstract

Influence of Temperature and Estimation of Enthalpy and Entropy for Reactive Extraction of Lactic Acid

Author(s): Hussein Salih Hussein and S. N. Shinde

This paper deals with lactic acid extraction by using tri-n-butyl phosphate (TBP) extractant dissolved in diluents (Methyl ether diketone (MIBK), 1-dedocanol & di ethyl ether) at different temperatures range (298, 313, 323, 333 K). Chemical equilibrium experiments have been carried out to investigate the effect of temperature on the extraction efficiency of tri-n-butyl phosphate (TBP) as well as on the equilibrium extraction constant. It was found that distribution coefficient (KD) decreased with increasing the temperature. However, an improved separation of the phases is observed. The extraction equilibrium constants have been determined using a mathematical model of reactive extraction. The apparent enthalpy and entropy of the reactive extraction with systems (TBP/MIBK, TBP/1-dedocanol TBP/di ethyl ether) are also determined.
