Monroe, Bruce M. published an article in 1977, the title of the article was Quenching of singlet oxygen by aliphatic amines.Synthetic Route of 2160-93-2 And the article contains the following content:

Rate constants for the quenching of singlet O (1O2) for 22 aliphatic amines were measured by following inhibition of the self-sensitized photooxidation of rubrene in CHCl3. A correlation of quenching rate with amine ionization potential was found for amines with unbranched alkyl groups. However, substitution of the C α to the N reduces the quenching rate from that predicted by the ionization potential, indicating that 1O2 quenching is sensitive to steric effects. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2

On February 7, 2018, Perinu, Cristina; Bernhardsen, Ida M.; Pinto, Diego D. D.; Knuutila, Hanna K.; Jens, Klaus-J. published an article.COA of Formula: C8H19NO2 The title of the article was NMR Speciation of Aqueous MAPA, Tertiary Amines, and Their Blends in the Presence of CO2: Influence of pKa and Reaction Mechanisms. And the article contained the following:

The diamine 3-(methylamino)propylamine (MAPA) and eight tertiary amines were studied as single and blended aqueous CO2 absorbents at different concentrations and ratios to investigate their reaction mechanisms. After absorption (40 °C) and desorption (80 °C) experiments, quant. 13C NMR experiments were performed on each liquid sample. After absorption, the following CO2-derived species were identified and quantified: (bi)carbonate in each amine system, primary and secondary MAPA carbamate and MAPA dicarbamate in MAPA systems, and tertiary amine carbonate in tertiary amine systems. Concerning desorption, the main CO2 species removed was (bi)carbonate, followed in the blends by MAPA dicarbamate. Since, after CO2 absorption, the concentration of MAPA dicarbamate was negligible in single MAPA and, in the blends, mainly increased at increasing pKa of the tertiary amines, it is concluded that the tertiary amines increase the availability of MAPA species to react further with CO2. MAPA and tertiary amines appear to influence each other also for the CO2 release. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).COA of Formula: C8H19NO2

The design of new dual-function inhibitors simultaneously preventing hydrate formation and corrosion is a relevant issue for the oil and gas industry. The structure-property relationship for a promising class of hybrid inhibitors based on waterborne polyurethanes (WPU) was studied in this work. Variation of diethanolamines differing in the size and branching of N-substituents (Me, Bu, and tert-butyl), as well as the amount of these groups, allowed the structure of polymer mols. to be preset during their synthesis. To assess the hydrate and corrosion inhibition efficiency of developed reagents pressurized rocking cells, electrochem. and weight-loss techniques were used. A distinct effect of these variables altering the hydrophobicity of obtained compounds on their target properties was revealed. Polymers with increased content of diethanolamine fragments with n- or tert-Bu as N-substituent (WPU-6 and WPU-7, resp.) worked as dual-function inhibitors, showing nearly the same efficiency as com. ones at low concentration (0.25 wt%), with the branched one (tert-butyl; WPU-7) turning out to be more effective as a corrosion inhibitor. Com. kinetic hydrate inhibitor Luvicap 55 W and corrosion inhibitor Armohib CI-28 were taken as reference samples. Preliminary study reveals that WPU-6 and WPU-7 polyurethanes as well as Luvicap 55 W are all poorly biodegradable compounds; BODt/CODcr (ratio of BOD and COD) value is 0.234 and 0.294 for WPU-6 and WPU-7, resp., compared to 0.251 for com. kinetic hydrate inhibitor Luvicap 55 W. Since the obtained polyurethanes have a bifunctional effect and operate at low enough concentrations, their employment is expected to reduce both operating costs and environmental impact.

On August 5, 2019, Brune, Veronika; Hegemann, Corinna; Mathur, Sanjay published an article.Safety of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Molecular Routes to Two-Dimensional Metal Dichalcogenides MX2 (M = Mo, W; X = S, Se). And the article contained the following:

New synthetic access to two-dimensional transition metal dichalcogenides (TMDCs) is highly desired to exploit their extraordinary semiconducting and optoelectronic properties for practical applications. We introduce here an entirely novel class of mol. precursors, [MIV(XEtN(Me)EtX)2] (MIV = MoIV, WIV, X = S, Se), enabling chem. vapor deposition of TMDC thin films. Molybdenum and tungsten complexes of dianionic tridentate pincer-type ligands (HXEt)2NR (R = Me, tert-Bu, phenyl) produced air-stable monomeric dichalcogenide complexes, [W(SEtN(Me)EtS)2] and [Mo(SEtN(Me)EtS)2], displaying W and Mo centers in an octahedral environment of 4 S and 2 N donor atoms. Owing to their remarkable volatility and clean thermal decomposition, both Mo and W complexes, when used in the chem. vapor deposition (CVD) process, produced crystalline MoS2 and WS2 thin films. X-ray diffraction anal. and at.-scale imaging confirmed the phase purity and 2D structural characteristics of MoS2 and WS2 films. The new set of ligands presented in this work open ups convenient access to a scalable and precursor-based synthesis of 2D transition metal dichalcogenides.

On June 30, 1994, Bazylak, Grzegorz published an article.Quality Control of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Chemometric characterization of alkanolamines using molecular descriptors and planar chromatography data. And the article contained the following:

Twenty nine congeneric alkanolamines, mainly derivatives of ethanolamine and diethanolamine, were analyzed by reversed phase TLC on octadecyl silica layers using either methanol – water (9 + 1, volume/volume) or acetonitrile-water (9 + 1, volume/volume) as mobile phase. The capacity factors were compared with data, taken from the literature, obtained by paper chromatog. on cellulose, using three different mobile phase systems. Seven topol. indexes and other mol. descriptors, reflecting structural differences between the solutes, were calculated All the data were subjected to principal component anal. and hierarchical cluster anal. to determine the main factors affecting the observed physicochem. similarities and dissimilarities of alkanolamines or their chromatog. behavior. Multivariate classification of the alkanolamines revealed slight differences between the results obtained by principal component anal. and hierarchical cluster anal. The usefulness of the calculated abstract principal component (which accounted for 99% of the variance in the data) as the independent variable in quant. structure-retention relations (QSRR) was examined to determine whether it could be used to predict alkanolamine retention in planar chromatog. systems.

On November 13, 1985, Schultz, Rose Ann; White, Banita D.; Dishong, Dennis M.; Arnold, Kristin A.; Gokel, George W. published an article.Computed Properties of 2160-93-2 The title of the article was 12-, 15-, and 18-Membered-ring nitrogen-pivot lariat ethers: syntheses, properties, and sodium and ammonium cation binding properties. And the article contained the following:

N-pivot lariat ethers of varying ring sizes can be prepared by cyclization of an amine or substituted diol. 12-Membered ethers I [R = PhCH2, 2-, 4-MeOC6H4, 2-MeOC6H4CH2, HO(CH2)3, Me2NCH2CH2, MeOCH2CH2; n = 1] were prepared by the method of M. Calverley and J. Dale (1982); this involves cyclo-bis-dialkylation of an amine with 1,11-diiodo-3,6,9-trioxaundecane. I (R = 2-O2NC6H4CH2, 3,6-dioxaheptyl, 3,6,9-trioxadecyl, 3,6,9,12-tetraoxatridecyl, 11-allyloxy-3,6,9-trioxaundecyl; n = 1) did not form in high yield by this method or were more conveniently prepared by alkylation of I (R = H, n = 1). The latter was prepared from I (R = PhCH2, n = 1) by hydrogenolysis. Monoaza-15-crown-5 derivatives I (R = allyl, Bu, Me3C, PhCH2, MeOCH2CH2, 3,6-dioxaheptyl, 3,6,9,12,15,18,21,24-octaoxapentacosyl, 2-MeOC6H4, 4-MeOC6H4, 2-MeOC6H4CH2; n = 2) were prepared by cyclizing RN(CH2CH2OH)2 with R1(OCH2CH2)3OR1 (R1 = MeSO2, 4-MeC6H4SO2). I (R = Me, 2-O2NC6H4CH2, 4-O2NC6H4CH2, Me3CO2CCH2, n =2) were prepared by the alkylation of I (R = H, n = 2) which was prepared by hydrogenolysis I (R = PhCH2, n = 2). Monoaza-18-crown-6 derivatives I (R = H, Me, PhCH2, MeOCH2CH2, 3,6-dioxaheptyl, 3,6,9-trioxadecyl, 3,6,9,12-tetraoxatridecyl, 3,6,9,12,15-pentaoxahexadecyl, 3,6,9,12,15,18,21,24-octaoxapentacosyl, 2-MeOC6H4; n = 3) were analogously prepared Studies involving NH4 cation binding show that the interaction of ring and side-chain with the cation is intramol. in MeOH solution; the Na cation binds similarly. X-ray crystal structure evidence confirms this for the solid state in the I (R = 2-MeOCH2CH2, n = 3)·KI complex. The strongest binding for Na occurs when 6 O are present, regardless of ring size, which suggests that a flexible macrocycle is directed by the cation to envelop and solvate in the geometry most appropriate for the cation.

Heussner, Kirsten; Grabau, Mathias; Forster, Johannes; Streb, Carsten published an article in 2011, the title of the article was Can Hydrophobic Interactions Influence Supramolecular Aggregation in Self-Assembled Organic-Inorganic Hybrid Structures?.Category: alcohols-buliding-blocks And the article contains the following content:

This study aims to provide insights into the ability of amphiphilic cations to influence the assembly of hybrid organic-inorganic crystal lattices using hydrophobic interactions. To study the hypothesis, a prototype amphiphilic cation, tert-butyldiethanolammonium, was employed together with molybdenum oxide clusters of increasing size and charge in the self-assembly of type I hybrid systems. The molybdate clusters were used as model inorganic building blocks as they can be formed in situ and their size and charge can be adjusted by pH control. Using this strategy, three hybrid structures were obtained and characterized using single-crystal x-ray diffraction, theor. bond valence sum calculations, elemental anal., FTIR spectroscopy, TG and theor. Hirshfeld anal. Heptamolybdate Na5[tBuNH(C2H4OH)2][Mo7O24]·ca. 14H2O (1) was isolated, which features sodium-linked dimeric cluster species and isolated octadecanuclear sodium clusters. Octamolybdate [tBuNH(C2H4OH)2]4[Mo8O26]·ca. 4H2O (2) was isolated, containing the octanuclear β-[Mo8O26]4- cluster. At low pH levels (below pH 2), [tBuNH(C2H4OH)2]14[Mo36O112(H2O)16][Mo36O112(H2O)14{tBuNH(C2H4OH)2}2]·ca. 36H2O (3) was obtained, which is based on a 36-center molybdenum oxide cluster. Crystallog. anal. of the assemblies showed that the formation of hydrophobic regions within the crystal lattice is affected by the size of the inorganic building blocks employed. In 1 and 2, the hydrophobic tert-Bu groups of the amphiphilic cations aggregate into hydrophobic assemblies. In contrast, the structural arrangement in 3 is dominated by the large inorganic cluster and the organic cations are incorporated as isolated units. This behavior is further supported by theor. Hirshfeld surface anal. of the organic counterions, which suggests that, with increasing cluster size, the contribution of long-range, hydrophobic intermol. interactions decreases, which is in line with the crystallog. anal. for 1-3. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Category: alcohols-buliding-blocks
