TOPOLOGICAL INVESTIGATIONS ON ASSOCIATION OF ALKANOLS - EXCESS VOLUMES OF ACRYLONITRILE ALKANOLS (C1-C10) AT 308.15-K

Excess volumes, V(E), of binary liquid mixtures of acrylonitrile with alkanols (C1-C-10) have been determined by continuous dilution dilatometry at 308.15 K as a function of composition. The excess volumes are negative for acrylonitrile-methanol, both negative and positive for acrylonitrile-alkanols (C2-C5) and positive for acrylonitrile-alkanols (C-6-C-10). The V(E) data have been analysed by graph theory. The graph-theoretical connectivity parameters of the third degree give information regarding the state of the species in the pure phase as well as in the mixture.
