What is it about?
Excess properties were studied for the binary mixtures containing n-octane, diisopropyl ether (DIPE) and benzene. But through literature survey, we confirmed that there is no experimental study for [DIPE + benzene + n-octane] mixtures. This paper showcases the excess properties of oxygenated fuel mixtures consisting of DIPE, alkanol, aliphatic and aromatic hydrocarbons.

Why is it important?
The physicochemical properties of compounds in multicomponent fluid mixtures are important for designing of distillation columns in refineries, The excess properties reflect the deviation from ideal behaviour and are function of size, shape and polarity of the mixing components. Benzene is selected owing to its use as an additive in gasoline due to its high octane number, DIPE is utilized as fuel oxygenate and n-octane represents hydrocarbons in the gasoline.
Perspectives
For the first time we have presented the excess properties of the the ternary fuel mixture [DIPE + benzene + n-octane] which is otherwise not available in the literature. This work has set up the bench marks for studying the thermodynamic properties of ternary mixtures utilizing the existing correlations and modifying them. Developing new correlations as well as modifying the existing correlations was done in order to predict the thermophysical properties from the pure component data or from the minimum data of the binary mixtures.
