PURPOSE:To provide an agent for forming clathrate complex, containing 1,1,6,6- tetraphenyl-1,6-dihydroxy-2,4-hexadiyne as an active component, and capable of separating a 3- and 4-picoline mixture easily and in high purity into its components having close boiling paints to unable the separation and purification by distillation. CONSTITUTION:The objective agent contains 1,1,6,6-tetraphenyl-1,6-dihydroxy-2,4- hexadiyne as an active component. The active component is added to a mixture containing 3-picoline, the mixture is optionally heated to complete the formation of the clathrate complex, and the produced crystal is separated optionally after cooling. The obtained clathrate complex is composed of the above active component and 3-picoline at a molar ratio of 1:1-2. The amount of the active component is 0.1-2 times mol based on the 3-picoline. The formation of clathrate complex is carried out preferably at 0-50 deg.C.
