Abstract
In this study, reactive extraction of glyoxylic acid (0.93 kmol.m(-3)) using Amberlite-LA2 (0.24 to 1.67 kmol.m(-3)) in five different alcoholic diluents is performed at 298 K. The extraction ability of Amberlite-LA2 is found to be in the order of isoamylalcohol (IAA) > nonan-1-ol > octan-1-ol > decan-1-ol > dodecanol. Maximum extraction efficiency, 98.92% is obtained at 1.67 kmol.m(-3) of Amberlite-LA2 in IAA. The values of stoichiometric coefficient (m), overall equilibrium constant (K-E) and individual constants (K-11, K-21, and K-12) are estimated. The effect of diluent on K-D is also quantified by applying LSER model using solvatochromic parameters of diluents.
