Densities and viscosities of the ethanolamines

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

“…These compounds are used for the industries such as the petroleum for the removal of the CO 2 and H 2 S from the petroleum streams, surfactants, detergents, personal-care products, textiles, agricultural products and many others. (1,2) The physical and thermodynamic properties of pure aminoalcohols such as density and viscosity, (3) thermal conductivity (4) and heat capacity (5) have been reported earlier. The densities and excess molar volumes of aqueous solutions, (6)(7)(8)(9) viscosities (10) and excess molar enthalpies of these mixtures (5,(11)(12)(13) have also been studied.…”

Models for viscosity, thermal conductivity, and surface tension of selected pure fluids as implemented in REFPROP v10.0

“…Data sources for vapor-phase viscosity were not found. Data from several limited liquid-phase data sets at atmospheric pressure (Blanco, Garcia-Abuin, Gomez-Diaz, Navaza, & Villaverde, 2013;R. M. DiGuilio, Lee, Schaeffer, Brasher, & Teja, 1992;J.-H. Song, Park, Yoon, Lee, & Lee, 1996;Yin, Zhu, & Ma, 2016) were used to obtain the coefficients in Table 2.…”

Excess properties of (alkyldiethanolamine +H2O) mixtures at temperatures from (298.15 to 338.15) K

“…(1,2) Densities, excess molar volumes, and excess molar enthalpies of (monoethanolamine, MEA, + H 2 O), (monomethylethanolamine, MMEA, + H 2 O), and (dimethylethanolamine, DMEA, + H 2 O) were studied at T = 298.15 K. (3) Excess molar volumes of aqueous solutions of (MEA + H 2 O), (diethanolamine, DEA, + H 2 O), and (triethanolamine, TEA, + H 2 O) (4) and of (methyldiethanolamine, MDEA, + H 2 O) and (ethyldiethanolamine, EDEA, + H 2 O) (5) were measured from T = (298.15 to 353.15) K. Densities and excess molar volumes of (DMEA + H 2 O) and (diethylethanolamine, DEEA, + H 2 O) were reported at T = (293.15 to 313.15) K. (6) Transport properties of pure ethanolamines (7) and (DEA + H 2 O) and (MDEA + H 2 O) have also been studied. (8) Heat capacities (9) and thermal conductivities (10) (12) and of (monoethylethanolamine,…”
