摘要：

As part of a project on thermodynamic properties of hydrogen-bonding solutions, limiting activity coefficients were measured in 10 binary systems of the type alcohol + solvent at temperatures between 293 K and 333 K. The systems are: methanol + tetrachloromethane, ethanol + hexane, ethanol + heptane, ethanol + cyclohexane, ethanol + tetrachloromethane, 2-methylpropan-2-ol (tert-butyl alcohol) + hexane, 1-hexanol + hexane, 1-hexanol + cyclohexane, 1-hexanol + tetrachloromethane, and 1-hexanol + toluene. Furthermore, new experimental results are reported on the vapor-liquid equilibrium for the system ethanol + heptane at 313 K. The measurements were carried out with a newly built headspace gas chromatograph.
