The relative ratio of three forms of N, N'-dimethylpiperazine in aprotic solvent was determined at room temperature by analyzing the curve of dielectrometric titration. The molar ratios of forms I, II, and III at 30° in dioxane were 0.880, 0.116, and 0.004, respectively, which were in good agreement with those of Allinger, et al. had obtained from the dipole moment of free diamine in benzene solution. The use of dielectrometric titration seemed to afford a particularly simple and direct method for conformational analysis of aliphatic di-tertiary amines.
