摘　　要：研究了用Ｃｙａｎｅｘ３０１［ＴＭ］铵盐在苯中重结晶以纯化Ｃｙａｎｅｘ３０１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，Ｃｙａｎｅｘ３０１主要以二聚形式存在。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.
