摘要: 研究了用Cyanex 301[TM]铵盐在苯中重结晶以纯化Cyanex 301的方法,该法收率62.4%,产品纯度>99%.测定了经纯化后产品的红外光谱,研究了纯化产品在-水正庚烷体系中的分配平衡及其在正庚烷中的缔合,浓度在0.2~1.0mo1/L范围,Cyanex 301主要以二聚形式存在。

Abstract: 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.

Key words: Cyanex 301, purification, recrystallization, aggregation
