Gravimetric and quantum-chemical study of interaction of Monoethanolamine vapor with silica surface
Journal of Thermal Analysis and Calorimetry, 2000Co-Authors: V. V. Lobanov, A. A. Chuiko, N. A. Burlaenko, V. E. Klymenko, Valentyn Tertykh, V. V. Yanishpolskii, M.i. TeretzAbstract:Kinetics of the Monoethanolamine vapor adsorption on the surface of silica previously deposited onto quartz plate was examined by the piezoelectric microweighing. With the assumptions which are in accord with the experimental data, the kinetic equation of the process was obtained and thus the adsorption and desorption constants were found. The structure of the possible adsorption complexes was studied in the framework of the quantum-chemical MNDO method and the conclusion was made that the two-center adsorption of the Monoethanolamine on the silica surface proceeds as a two-stage process with the participation of both functional groups. The bonding is mainly effected owing to the proton-acceptor properties of amine groups.

Organosiloxane and Monoethanolamine transformations on fumed silica and alumina-silica surfaces
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1996Co-Authors: A. A. Chuiko, G. Ya. Guba, V. A. Pokrovskii, M.i. TeretzAbstract:Abstract We have perfomed thermogravimetric, infrared spectroscopic and mass spectroscopic studies of the structure and thermal transformations of surface groups formed in the process of chemical modification of fumed silica and alumina-silica by Monoethanolamine and organosiloxanes. Thermal transformations of organosiloxanes and Monoethanolamine on fumed silica and on alumina-silica surfaces have been shown to occur through different paths due to variation of the nature of the surface active sites of oxides under investigation.

Volumetric properties of aqueous solutions of Monoethanolamine, mono- and dimethylethanolamines at temperatures from 5 to 80 °C I
Thermochimica Acta, 2002Co-Authors: Yadollah Maham, T. T. Teng, Loren G. Hepler, Alan E MatherAbstract:Abstract Densities of aqueous binary mixtures of Monoethanolamine, monomethylethanolamine and dimethylethanolamine were measured over the whole range of compositions at temperatures varying from 5 to 80 °C. The density of Monoethanolamine+water mixtures shows a maximum (x2=0.43 at 5 °C). The density behavior of Monoethanolamine+water and dimethylethanolamine+water mixtures is different from the Monoethanolamine+water system. The composition dependence of the densities of these two mixtures was classified in two distinct zones. This separation line occurs at x2=0.20 for Monoethanolamine+water and x2=0.12 for the dimethylethanolamine+water system. In the low concentration zone, the density values exhibit a minimum and a maximum at increasing ethanolamine concentration, while in the high concentration zone, the density values approach the density of the pure alkanolamine in a monotonic fashion. The excess molar volume of these mixtures is dependent on the structure of the ethanolamines: V E (Monoethanolamine + water ) E ( Monoethanolamine + water ) E ( dimethylethanolamine + water ).
