Thermodynamic properties of binary mixtures of I-hexyne and polar organic solvents



Vapor-liquid equilibrium data for polar solvent-hydrocarbon mixtures are relatively plentiful for paraffins and aromatics; they are somewhat less plentiful for olefins. However, almost no data at all have been published for such mixtures wherein the hydrocarbon possesses a triple bond. This paper reports vapor-pressure measurements of binary mixtures of 1-hexyne with acetone, acetonitrile, dimethyl carbonate, nitroethane and dimethyl formamide in the temperature range 0 to 70°C. The results are compared with those for polar solvent-hydrocarbon mixtures wherein the hydrocarbon is paraffinic, olefinic, or aromatic.
