, p. 1926 - 1928 (2010)
A method for the synthesis of 1-chlorosilatrane by the reaction of organyltrichlorosilanes RSiCl3 (R = Vin, Ph) and tetrachlorosilane with triethanolamine or its hydrochloride was developed. This simple and economical method allows obtaining 1-chlorosilatrane in 60% yield.

In this work, the reaction of 2,2′,2″-nitrilotriethanol (NTE) with a 1:1 mixture of CdI2 and HgI2 is investigated. The complex [Cd(NTE)2][Hg2(μ-I)2I4] was synthesized and identified by elemental analysis, FT-IR, 1H NMR spectroscopy and single-crystal X-ray diffraction. The structure of the [HNTE]Cl salt is also presented. In the crystal structure of the complex, the cadmium atom has a CdN2O6 environment in a slightly distorted cube geometry. This geometry is one of the rare cube geometries with a minimum distortion among the Cambridge Structural Database structures for cadmium complexes. The anionic moiety has a binuclear structure with the mercury atoms being in tetrahedral environments. In the network of the complex, in addition to O-H ? I hydrogen bonds, there are I ? I interactions which lead to ten-membered rings.
Solubilities of triethanolamine hydrochloride ionic liquid in aqueous hydrochloric acid solutions with concentrations from (0 to 8.37) mol·kg-1
Zhang, Yan,Li, Zhibao
, p. 4434 - 4439 (2010)
The (solid + liquid) phase equilibria of triethanolamine hydrochloride ([HTEA]Cl) ionic liquid and aqueous hydrochloric acid solutions with concentrations from (0 to 8.37) mol·kg-1 were determined by a dynamic method within the temperature range of (285.70 to 344.65) K. Solubilities of [HTEA]Cl were found to increase with increasing temperature for all the investigated solutions. However, solubilities of [HTEA]Cl in aqueous hydrochloric acid decrease with the increment of the concentration of the acid due to the common ion effect. KSP values of [HTEA]Cl were obtained by use of the solubility data of [HTEA]Cl in water. The modified Apelblat equation was used successfully to correlate experimental data of solubilities in hydrochloric acid. Molar dissolution enthalpy ΔHSol of [HTEA]Cl in hydrochloric acid solutions was determined with the newly obtained Apelblat equation parameters.

A novel ammonium salt, an ionic liquid (ILs) was synthesized at room temperature. Its structure was elucidated by elemental analyses and various spectroscopic techniques like FT-IR, 1H and 13C NMR and ESI-MS spectrometry. Thermal studies were also carried out to get thermal stability of the ionic compound. X-ray crystallographic study was carried out to ascertain the structure of ammonium cation which is bonded to three anion via O-H Cl intermolecular hydrogen bonds. Synthesized compound was also investigated for in vitro antimicrobial study against number microbes and results showed excellent results.
Deep eutectic solvents as attractive media for CO2 capture

We report a family of deep eutectic solvents (DESs) consisting of various hydrogen bonding donor-acceptor pairs as CO2 capturing media. These DESs capture CO2via carbamate formation upon reaction between their hydrogen bonding donor units and CO2. Among the members tested herein, a DES made up of monoethanolamine hydrochloride-ethylenediamine exhibits an unprecedentedly high gravimetric uptake of 33.7 wt% with good initial kinetics (25.2 wt% uptake within 2.5 min) and recyclability. The given DES also shows sustainable performance in the presence of water, decent tolerance against temperature rise, and a relatively low heat of absorption which is attractive for regeneration. Even with the high gravimetric uptake, the DES has a far more suppressed corrosiveness compared to its pure monoethanolamine and ethylenediamine counterparts due to low oxygen/moisture permeability and the hydrogen bonding network that alleviates the corrosion redox cycle. The observed excellent properties in various key aspects of CO2 capture suggest that DESs are strong candidates to replace the conventional monoethanolamine-based scrubbing technology and are worth further exploration.

, p. 1904 - 1908 (2015/02/02)
A unique one-stage synthesis of tetrakis(2-hydroxyethylammonium) salts, precursors of new hypervalent silicon compounds, has been developed. The vibration spectra of tetrakis(2-hydroxyethylammonium) chloride and its triethanolamine precursor and metabolite have been studied by IR spectroscopy and quantum chemistry. Analysis of alterations in the modes with increasing number of HOCH2CH2 groups has been performed.

experimental part, p. 119 - 126 (2012/04/04)
The research goal was to synthesize and structurally characterize a silatrane intended to be subsequently incorporated into metal complex structures. 3-Aminopropyltrialkoxysilane was reacted with triethanolamine in 1:1 molar ratio, either in bulk, in the presence of metallic sodium, or in a solvent mixture. 1-(3-Aminopropyl)silatrane in carbamate form or having free amine groups was obtained. The latter was reacted with 2-hydroxybenzaldehyde, 2,4-dihydroxybenzaldehyde and CoCl2 or with CoCl2 only. The crystalline reaction products were characterized by elemental and spectral (FTIR and 1H NMR) analyses and single crystal X-ray diffractometry, which revealed the formation of new, either sought (1-(3-aminopropyl)silatrane, 1-(3-salicyliminopropyl)silatrane) or unexpected (N-carboxylated 1-(3-aminopropyl)silatrane and 1-chlorocobaltrane) structures.

Voronkov,Albanov,Aksamentova,Adamovich,Chipanina,Mirskov,Kochina,Vrazhnov,Litvinov
experimental part, p. 2339 - 2346 (2010/05/15)
New method of synthesis of tris(2-hydroxyethyl)ammonium salts, 2,8,9-trihydroprotatranes X-[HN(CH2CH2OH) 3]+, based on the reaction of tris(2-hydroxyethyl)amine (triethanolamine) with ammonium salts NH4X (X = F, Cl, Br, I, NO 3, ClO4) was developed. 1H, 13C, 15N NMR and IR spectra of these protatranes were investigated, as well as those of their analogs with X = RCH2COO (R = H; 2-MeC 6H4O; 2-Me-4ClC6H3O; 2-MeC 6H4S; 4-ClC6H4S; 4-ClC 6H4SO2; 3-IndS; 3-(PhCH2-IndS) prepared from the corresponding acids RCH2COOH and triethanolamine. The parameters of IR and NMR spectra of the studied protatranes were governed by the nature of substituent X, which also determined the character of the intra and intermolecular hydrogen bonds NH...O and OH...O in the protatrane framework.

-
Page/Page column 55-56, (2008/06/13)
Disclosed is a spectrofluorimetrically detectable luminescent composition consisting essentially of at least one energy transfer acceptor lanthanide(III) complex having an emission spectrum maximum in the range from 300 to 2000 nanometers and a luminescence-enhancing amount of at least one energy transfer donor selected from the group consisting of a fluorophore, a lumiphore, an organic compound, a salt of an organic ion, a metal ion, a metal ion complex, or a combination thereof. Such energy transfer donor enhances the luminescence of at least one energy transfer acceptor lanthanide(III) complex, with the conditions that the emission spectrum of any energy transfer donor differs from that of its energy transfer acceptor lanthanide(III) complex; and such energy transfer donor can be dissolved to form a unitary solution in a solvent having an evaporation rate at least as great as that of water.
