The structure of some mixed high-molecular weight amine salt solutions was studied by conductance, cryoscopic, and solubility methods. Experimental results showed that mixed ionic clusters are formed in tribenzylamine hydrochloride-tribenzylamine nitrate-chloroform, tribenzylamine hydrochloride-tribenzylamine hydrobromide-chloroform, and trinonylamine hydrochloride-trinonylamine hydrobromide-benzene solutions. In the mixed solution of trinonylamine hydrochloride and sulfate, however, the formation of mixed ionic clusters is not apparent.
