Equilibrium study on reactive extraction of propionic acid with N1923 in different diluents

, 2009
The equilibrium for the propionic acid extraction by N1923 in three diluents, represented as proton-donator (n-octanol), polar (butyl acetate). inert (hexane) types, have been studied. The diluents had a significant influence on the equilibrium.
