NEW measurements and modeling data of excess molar enthalpy HE at atm. pressure and temperatures of (298.15 and 313.15) K using a quasi-isothermal flow calorimeter are presented in this work for the ternary system diethylene glycol monomethyl ether glycol (2-(2-methoxyethoxy)ethanol) + 1-hexene + cyclohexane and the corresponding binary systems over the whole composition range. All the binary and ternary systems present an endothermic behavior at the chosen temperatures The exptl. data of the binary and ternary systems were correlated using the modified Redlich-Kister equation, NRTL and UNIQUAC models. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Product Details of 111-77-3).
2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Product Details of 111-77-3
