A new method has been developed for the prediction of the Reid vapor pressure of gasolines containing oxygenates such as MTBE, ethanol and methanol. This method accounts for the significant deviations in the liquid phase which dominate the sensitivity of the Reid vapor pressure to small additions of oxygenates. Results obtained over a wide composition range show that the Reid vapor pressure increases most rapidly with methanol additions, to a lesser degree without MTBE, and least rapidly with ethanol.
