ABSTRACT
Vapor-liquid equilibrium (VLE) measurements have been made for the binary systems ethene oxide + dodecane at four temperatures from (303.15 to 393.15) K, ethene oxide + 1-decanol at three temperatures from (303.15 to 363.15) K, and ethene oxide + 1-dodecanol at four temperatures from (313.15 to 433.15) K for varying mole fractions. An adiabatic calorimeter was used as a static apparatus for the VLE measurement. The obtained temperature, pressure, and liquid mole fraction data (T-p-x data) were used for fitting binary interaction parameters for the predictive Soave-Redlich-Kwong equation of state (PSRK EoS). The applicability of fitted parameters to other systems containing identical structural groups is shown by means of the binary system ethene oxide + 2-methylpropane and ethene oxide + 1-dodecanol.
