Isobaric vapor-liquid equilibrium in the systems ethyl 1,1-dimethylethyl ether+2,2,4-trimethylpentane and plus octane

Consistent vapor-liquid equilibrium data for the binary systems ethyl 1,1-dimethylethyl ether (ETBE)+ 2,2,4-trimethylpentane and ethyl 1,1-dimethylethyl ether + octane at 94 kPa, including pure component vapor pressures of 2,2,4-trimethylpentane and octane, have been experimentally determined. The measured systems deviate slightly from ideal behavior, can be described as symmetric regular solutions and present no azeotropes. Boiling points were correlated using the Wisniak-Tamir equation.
