A method of purifying Cyanex 301 by recrystallization of its ammonium salt in benzene was studied. The recovery of this method is 62.4% and purity of the product is >99%. The infrared spectrum of purified Cyanex 301 is given. The partition equilibrium of purified Cyanex 301 between n-heptane and aqueous phase and its aggregation in n-heptane were studied. The results show that purified Cyanex 301 is mainly present as a dimer in the concentration range of 0.2 to 1.0 mol/L in n-heptane.
