β¦ Synopsis
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 b formamide b N,N-dimethylformamide b 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.
