Topological investigations on association of alkanols. Excess volumes of acrylonitrile–alkanols (C1–C10) at 308.15 K

Abstract

Excess volumes, V^E, of binary liquid mixtures of acrylonitrile with alkanols (C₁–C₁₀) 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 (C₆–C₁₀). 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.
