Isobaric Vapor–Liquid Equilibrium of tert-Butyl Alcohol + Water + Triethanolamine-Based Ionic Liquid Ternary Systems at 101.3 kPa
Journal of Chemical & Engineering Data, 2015Co-Authors: Zhigang Zhang, Qiang Zhang, Qinqin Zhang, Tao ZhangAbstract:Isobaric vapor–liquid equilibrium (VLE) data for the tert-butyl alcohol (t-BuOH) + water + Triethanolamine (TEA), t-BuOH + water + Triethanolamine formic acid ([TEA][Fc]), t-BuOH + water + Triethanolamine acetic acid ([TEA][Ac]), and t-BuOH + water + Triethanolamine lactic acid ([TEA][Lc]) ternary systems were measured at 101.3 kPa. The results indicated that all the three ILs produced a more obvious effect on the VLE behavior of t-BuOH + water system than TEA, and eliminated the azeotropic point in the whole concentration range. [TEA][Lc] was the best solvent for the separation of the t-BuOH + water system by extractive distillation among the three ILs investigated. The experimental VLE data for the ternary systems were correlated with the NRTL model equation, and good correlations were obtained with an average relative deviation of 2.4 %.

DENSITIES, VISCOSITIES AND SURFACE TENSIONS OF AQUEOUS MIXTURES OF SULFOLANE+Triethanolamine AND SULFOLANE + DIISOPROPANOLAMINE
Journal of Chemical & Engineering Data, 2011Co-Authors: Sara Ahmad Kelayeh, Amir Hossein Jalili, Cyrus Ghotbi, Masih Hosseini-jenab, Vahid TaghikhaniAbstract:Densities and viscosities of aqueous solutions containing sulfolane and ternary aqueous solutions of sulfolane and Triethanolamine and ternary aqueous solutions containing sulfolane and disopropanolamine and also equilibrium surface tensions of the above ternary aqueous solutions were measured at temperatures ranging from (303.15 to 343.15) K and atmospheric pressure. The overall concentration of sulfolane, Triethanolamine, and diisopropanolamine in solutions varied in the range of 0 to 16.5, 0 to 43, and 0 to 40 mass percent, respectively. Using the density, viscosity, and surface tension of pure water as the solvent, the corresponding experimental values obtained for the investigated solutions were correlated with temperature and concentration by a modified Setchenow equation.

porous behavior and dielectric properties of barium strontium titanate synthesized by sol gel method in the presence of Triethanolamine
Chemistry of Materials, 2000Co-Authors: Pramod K. Sharma, Vasundara V. VaradanAbstract:This investigation presents a novel method of preparation of barium strontium titanate (BST) from [Ba(2,4-pentadionate)-Sr(2,4-pentadionate)-Ti(OC3H7)4-TEA-i-PrOH-water] system. Triethanolamine (TEA) was used as an additive, which prevents the precipitation of oxides from the alcoholic titanium isopropoxide solution in the presence of excess water. An increasing molar ratio of water from 4.5 to 6.5 did not show any precipitation in the precursor sols in the presence of Triethanolamine. Thermal behavior of the xerogel was studied by thermal gravimetric analysis (TGA). X-ray diffraction (XRD) indicated that the pure BST phase was crystallized at 900 °C. Triethanolamine was observed to influence the porous behavior of the final powders. Pore diameter of the powder calcined at 900 °C, was increased from 0.013 μm to 0.080 μm when the molar ratio of Triethanolamine increased from zero to four. Therefore, a porous powder of BST was obtained at a higher molar ratio of Triethanolamine. Porous behavior was also stu...
