On September 30, 1997, Bazylak, Grzegorz; Aboul-Enein, Hassan Y. published an article.Product Details of 2160-93-2 The title of the article was Chemometric account for retention of lysosomotropic alkanolamines in planar chromatography systems. And the article contained the following:

Planar chromatog. retention data (in form of thermodynamically meaningful RM coefficients) for twelve model alkanolamines, indicating lysosomotropic activity, were determined in eighty chromatog. systems using eight different silica gel layers with varied chem. bonded stationary phases. In performed TLC experiments, aqueous binary mobile phases containing methanol or acetonitrile as organic modifier, in five different proportions, were applied. Addnl., nine quantum chem. descriptors were calculated for test solutes by a semi-empirical mol. modeling procedure (AM1) to describe their structural properties. Chemometric technique by the multivariate method of principal components anal. (PCA) was applied to the all completed chromatog. retention and computational chem. data for identification of the most selective and useful planar chromatog. systems as well as mol. interactions of solutes which affect their retention phenomena in the particular separation mode. The statistically significant relationship was revealed between quant. measure of antimicrobial activity of alkanolamines and values of calculated scores of principal components. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Product Details of 2160-93-2

A PVC-membrane electrode based on a recently synthesized 18-membered macrocyclic diamide is presented.

The electrode has a response time of ∼10 s and can be used for at least 2 mo without any divergence. The proposed sensor revealed very good selectivities for Co2+ over a wide variety of other metal ions, and could be used over a wide pH range (3.0-8.0).

On August 31, 2013, Ben Youssef, Ismail; Alem, Halima; Sarry, Frederic; Elmazria, Omar; Jimenez Rioboo, Rafael; Arnal-Herault, Carole; Jonquieres, Anne published an article.Category: alcohols-buliding-blocks The title of the article was Functional poly(urethane-imide)s containing Lewis bases for SO2 detection by Love surface acoustic wave gas micro-sensors. And the article contained the following:

Functional polymers containing Lewis bases are known as promising materials for the elaboration of highly sensitive micro-sensors for acid gas detection. In this work, poly(urethane-imide)s (PUIs) with Lewis bases were synthesized in two steps only from various functional diols (N-methyldiethanolamine, N-tert-butyldiethanolamine, N-phenyldiethanolamine and 1,4-diethanolpiperazine) containing one or two tertiary amine groups with different chem. structures. The synthesis led to high yields, high mol. weights and a good control of the PUI amine content. These good film-forming polymers were then used as SO2 sensitive coatings on Love surface acoustic wave (L-SAW) micro-sensors. The phys. and mech. properties required for an optimal micro-sensor design were determined by High Resolution Brillouin Spectroscopy of PUI thin layers. Three-layer micro-sensors were developed by respecting the conditions for the L-SAW generation. The three-layer structure included Quartz ST-90 as the piezoelec. substrate, a ZnO guiding layer and a PUI sensitive layer. These micro-sensors were weakly sensitive to temperature and thus compatible with the targeted application. The exptl. results for SO2 detection showed that all the PUI coatings greatly improved the sensitivity compared to a micro-sensor without polymer coating. The basicity of the amine groups was not determining for the micro-sensor sensitivity to the SO2 acid gas and the key factor was their steric hindrance. Finally, the micro-sensor sensitivity increased with the accessibility of the amine groups in the order Piperazine-diol < tBu-DEA ≃ Ph-DEA ≪ MDEA. The experimental process involved the reaction of 2,2'-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Category: alcohols-buliding-blocks

On February 28, 2019, Shoukat, Usman; Baumeister, Eva; Pinto, Diego D. D.; Knuutila, Hanna K. published an article.Electric Literature of 2160-93-2 The title of the article was Thermal stability and corrosion of tertiary amines in aqueous amine and amine-glycol-water solutions for combined acid gas and water removal. And the article contained the following:

Thermal stability and corrosion of seven tertiary amines (20 weight%) solutions in water and water-glycol [ethylene glycol (MEG)/tri-ethylene glycol (TEG)] loaded with CO2 in stainless steel reactors has been studied for combined acid gas removal along with hydrate control. The pKa of the tested amines varied from 7.85 to 9.75. Titration and inductivity coupled plasma mass spectrometry (ICP-MS) are used to quantify the remaining alkalinity and metal concentrations in amine solutions resp. The presence of MEG and TEG profoundly influenced the amine stability. Triethanolamine had the highest thermal stability. Furthermore, the results also show that an increase in pKa generally decreases corrosion. 3-(Diethylamino)-1,2-propanediol (DEA-1,2-PD) has the lowest corrosion in water and water-TEG solutions while 2-(Diethylamino)ethanol (DEEA) has the least corrosion in water-MEG solutions The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Electric Literature of 2160-93-2
