Densities and Refractive Indices of Aqueous Solutions of Diethylenetriamine, and Triethylenetetramine, and Tetraethylenepentamine.

Density, viscosity, and excess properties of aqueous solution of diethylenetriamine (DETA)

“…The density and viscosity of pure DETA were also measured in the temperature range between (293.15 and 363.15) K and also plotted in the same figures 2 and 3. From figure 2, the measured density values of pure DETA were found to be between the two references value [14,15] whereas at 298.15 K, it seems to agree with the result reported by Rouleau and Thompson [16]. From figure 3, the measured viscosity values were found to be reasonably well with the reported data by Dow [14] whereas at temperature up to 313.15 K, the viscosity seems to be higher than to the reported data by DIPPR [15].…”

“…The discrepancy of the data might be attributed to the purity of the chemical. [11]; h, [12]; and of pure DETA: s, this work; +, [14]; Â, [15]; * , [16] at various temperatures. The measured density of aqueous DETA solutions over the entire range of mole fractions x 1 and temperature range between (293.15 and 363.15) K are listed in table 2 and plotted in figure 4.…”

Densities and Viscosities of Binary and Ternary Solutions of Triethylenetetramine, 2-Amino-2-methyl-1-propanol, and Water for Carbon Dioxide Capture

“…The validation of the experimental technique employed in this study is presented in Table , where the density and viscosity values of pure H 2 O, AMP, TETA, and binary solutions TETA + H 2 O and AMP + H 2 O from the literature are also compared with those obtained here (experimentally). Table also presents the deviation from literature, ,,− which is calculated by eq . where Y lit represents the viscosity and the density in the literature and Y exp is the experimentally obtained viscosity and density (this study). Furthermore, Table indicates the consistency between the values of density and viscosity in this study and in previous studies.…”

“…Many studies have been conducted to measure the viscosities and densities of various TETA solutions: the density of TETA + H 2 O (9.2 wt % to pure TETA) at 298.15 K; the viscosity and density of methyldiethanolamine (MDEA) (20 and 40 wt %) + TETA (3 and 6 wt %) + H 2 O from 298.15 to 333.15 K and the viscosity of TETA (5 and 10 wt %) + H 2 O from 293.15 to 333.15 K; the viscosities of MDEA (22, 24, and 26 wt %) + TETA (4, 6, and 8 wt %) + H 2 O and MDEA (22, 24, and 26 wt %) + TETA (2, 4, and 6 wt %) + N-(2-aminoethyl) piperazine (AEP) (2, 4, and 6 wt %) + H 2 O at 298.15 K; and the density and viscosity of AMP (2.5 M) + TETA (0.1, 0.3, and 0.5 M) + H 2 O from 308 to 318 K …”

Volumetric and Viscometric Properties for Binary and Ternary Solutions of Diethylenetriamine, N,N-Diethylethanolamine, and Water

“…Although the densities of DETA are lower than water, the densities of DETA aqueous solution increases first and then decreases with the augment of amine concentration, and the maximum value appears about at x 1 = 0.2 for each temperature, which is in accord with the results reported by Hartono 30 and Rouleau. 38 The…”
