In this work, we extend the Group Contribution with Association Equation of State (GCA-EOS) to model the phase behavior of mixtures comprising ethers and alcs. The model parametrization was done using few binary vapor-liquid equilibrium data sets of linear monoethers. We also model the behavior of branched ethers, traditionally used as fuel additives, as well as that of polyethers, which are nowadays being proposed as potential biofuels. Therefore, we investigate, not only the phase equilibrium, but also excess enthalpies of these three types of ethers in mixtures with alcs. Finally, we show that the GCA-EOS is able to predict the phase behavior of polyethers, as well as that of branched ethers, using a group contribution approach. This work is part of a broader project for the development of a robust and predictive thermodn. model for process and product design in the context of biomass valorization. In addition, the parametrization reported here aims to provide a reliable framework specific for the description of thermodn. properties of biofuel blends. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Quality Control of 2,5,8,11-Tetraoxadodecane).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Quality Control of 2,5,8,11-Tetraoxadodecane
