Ethers and alcohols are being added to hydrocarbon fuels to produce the current generation of “clean gasolines” which are claimed to reduce air pollution. Also, alcohols provide a renewable energy source. However, the addition of oxygenates can change the volatility (as measured by the Reid vapor pressure) of a hydrocarbon mixture. This article reviews the equipment and measurement methods commonly used to study the vapor–liquid equilibrium (VLE) of hydrocarbon–oxygenate and gasoline–oxygenate mixtures. Detailed tables present those oxygenate–hydrocarbon mixtures for which VLE data are available.
