The reactive extraction of Bixa orellana seed pigment norbixin with cationic carrier Aliquat‐336 (QCl) in a two phase system has been studied. A raw alkali extract of Bixa orellana pigments in 0.5% sodium hydroxide solution is used as aqueous phase and Aliquat‐336 dissolved in hexane as solvent is used as the organic phase. In the aqueous alkaline phase, the pigment (bixin + norbixin) exists as sodium...
