Abstract

Forward extraction of shikimic and quinic acids with tridodecylamine (TDA)/1-heptanol is favored at low temperature. In back extraction, higher temperatures and the addition of oleic acid as a competitive displacer provided 80% recovery for shikimic acid and 70% recovery for quinic acid. Higher recoveries are possible since these values are limited by the forward extraction step. The effect of temperature swing on carboxylic acid extraction by amines is primarily due to the change in amine basicity with temperature. The addition of a displacer lowers the energy cost by lowering the temperature required in back extraction.
