Density and excess molar volumes of aqueous solutions of morpholine and methylmorpholine at temperatures from 298.15 K to 353.15 K

Volumetric properties of aqueous solutions of diethylsulfoxide at temperatures from 298.15 K to 343.15 K

“…This explanation agrees well with the fact that very strong interactions take place between DESO and water, even stronger than those between DMSO and water [5]. Hydrophobic hydration, which had been considered to explain the lowering of the excess molar volume of (methylmorpholine + water) mixtures compared with the excess molar volume of the aqueous solutions of morpholine [12], cannot be a factor in our case. Although at low concentration in the system (DESO + H 2 O) hydrophobic interactions predominate [5].…”

Volumetric and viscometric properties of aqueous solutions of N-(2-hydroxyethyl)morpholine at T=(293.15, 303.15, 313.15, 323.15, 333.15)K

“…Disruption of the water structure and the formation of the new complex are due to hydrogen bonding between the hydroxyl groups of water and NHEM. The values of excess molar volumes for {NHEM (1) + water (2)} in this study is less negative than those obtained for (morpholine + water) [10], Therefore, another factor effects on V E of our mixtures is the size and shape of the two component liquids of the mixture. Further investigation is needed for understanding the interactions between water on one side and the morpholine derivatives on the other side.…”

Application of QSPR to Mixtures

“…alcohols, esters, alkanes, ethers, ketones, amines, etc. The experimental density data of 271 binary mixtures was collected from the literature − and are reported in Table . The densities of 271 mixtures were reported at various mole fractions resulting in a total of 4679 mixture data points.…”
