European energy policy is promoting the use of bio-fuels for transportation. Bioethers and bioalcohols are used as blending agents for enhancing the octane number. Their effects are to make gasoline work harder, help engine last longer and reduce air pollution. They also cause changes in the fuel properties. Development of renewable fuels needs both knowledge of new thermodynamic data and improvement of clean energy technologies. In this context, the use of ethanol of vegetable origin in its manufacture process, increases the interest of ETBE or bio-ETBE as oxygenated additive. A complete study of the behaviour of mixtures ETBE + hydrocarbons is presented. Some experimental data concerning vapor liquid equilibria and heats of mixing were determined in our laboratory. All the techniques are of high accuracy. The data were reduced by well-known models as NRTL and used to model the thermodynamic properties.
