Lactic acid distribution coefficient

The distribution coefficient has been investigated as a function of various process variables. It is defined as a ratio of the total lactic acid concentration in the organic and the aqueous phases (Equation 2.4). Lactic acid can exist as two forms in aqueous solution, namely, the undissociated and dissociated forms. Lactic acid exists as an undissociated form (HLA) in the aqueous solution when pH < p Ta (p Ta = 3.86, 25°C) [2]. But in the organic phase, lactic acid is always present in the undissociated form.
