In this paper, the authors report the pure component vapor pressures of methyl tert-butyl ether (MTBE), 2,2,4-trimethylpentane (TMP), and methylcyclohexane (MCH) and P-T-x-y data for MTBE separately with TMP and MCH, for MTBE with four- and eleven-component simulated gasoline mixtures, and for ethanol (ETOH) with the eleven-component simulated gasoline mixture over a temperature range from 15 to 60 [degrees]C. In addition we report static cell (P-T-x) data at -6.7 [degrees]C for the same mixtures. The data the authors report here is useful for developing activity coefficient and equation of state models to predict the shift in equilibrium pressures and vapor compositions when oxygenates, such as ethers or alcohols, are added to gasoline in order to increase the octane rating and/or decrease pollution emissions on combustion.
