摘要：

Molar excess volumes have been measured for 1,4-dioxane (A) + formamide, or N,N-dimethylformamide, aniline, N,N-dimethylaniline (B) mixtures at 308.15 K. For an equimolar A + B mixture, molar excess volumes follow the sequence: aniline < formamide < N,N-dimethylformamide < N,N-dimethylaniline. The excess volume data have also been rationalized by graph-theoretical arguments. This analysis has further yielded information about the state of association in aniline, formamide and N,N-dimethylformamide that is consistent with the existing views on their nature of association. The existence of molecular entities in these mixtures has also been supported by their infrared spectral studies. (C) 2010 Elsevier B.V. All rights reserved.
