摘要: Abstract A group-contribution model for associated solutions is presented which an extension of the LFAS (Lattice-Fluid Associated Solutions) molecular model. Like LFAS, present equation-of-state valid both gaseous and liquid state,up to critical or supercritical region. Each group characterized by four Lattice-Fluid scaling constants over extended range external conditions. Only binary interactions are considered. The has been applied a number 1-alkanol + n-alkane systems including five key suggested IUPAC. properties considered : vapor pressures,heats vaporization,and orthobaric densities pure 1-alkanols n-alkanes, heats mixing,volumes mixing,and vapor-liquid equilibria in 1-alkanol+n-alkane mixtures. predictive character its limitations discussed.
