In this work, new exptl. data on the isobaric vapor-liquid equilibrium (VLE) of binary aqueous systems, with six different glycol ethers (glymes), some of which are currently used in the Selexol process, were measured at three different pressures, namely 0.05, 0.07, and 0.1 MPa. From the exptl. data, the water activity coefficients were estimated using the modified Raoult’s law and used to infer about the effect of the glymes structure on their interactions with water. Moreover, using a coarse-grain mol. model previously proposed in the framework of the soft-SAFT equation of state (EoS) for both glycols and glymes, the exptl. data were successfully correlated with a single state-independent binary interaction parameter and average absolute deviations from the exptl. data of 1.30 K. Furthermore, the model was used in a predictive manner to obtain the water activity coefficients in the whole composition range, providing useful insights into the systems non-ideality. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Name: 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. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Name: 2,5,8,11-Tetraoxadodecane
