On June 30, 1987, Robert, Dominique; Gawad, Hoda Abdel; Riess, Jean G. published an article.SDS of cas: 2160-93-2 The title of the article was Fluorophosphoranes as Lewis acids. The conditions of access to hexacoordinated neutral adducts via the intramolecular addition of an electron donor. And the article contained the following:

The preparation of bicyclic neutral hexacoordinated fluorophosphorus adducts (I) from RPF4 (R = F, Me, Ph) and (Me3SiOCH2CH2)2X (X = O, S, NH, NMe, NCMe3, NPh) was examined Adduct I was formed predominantly only in the case where R = F and X = S. In all the other cases there was a strong tendency to form ionic species. The 8-membered dialkoxyfluorophosphorane model precursor II (X = CH2) does not form easily, and the driving force towards the formation of the very stable RPF5- anions and of tetracoordinated phosphorylated species leads to its easy decomposition The monocyclic adducts of type III and IV are not easier to prepare: compound V only could be obtained where X = NH2 and R = F, while the spirophosphorane VI was isolated when R = Ph. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2

Osman, F. H.; El-Hamouly, W. S.; Abdel-Gawad, M. M.; Abbasi, M. M. published an article in 1982, the title of the article was The behavior of 2,2′-(tert-butylimino)diethanol toward five-membered heterocycles containing phosphorus(III).Safety of 2,2′-(tert-Butylazanediyl)diethanol And the article contains the following content:

The reaction of 2,2′-(tert-butylimino)diethanol Me3CN(CH2CH2OH)2 (I) with dioxaphospholanes II (X = Cl, NMe2) gave III. Thermal reaction of III with I gives a complete rearrangement yielding a mixture of spirophosphorane IV, V, and traces of another product. III reacts with Ph azide to give a mixture of penta- and tetracoordinated phosphorus structures VI and VII, resp. Biacetyl condenses with III to give VIII. Reaction of dioxaphospholane IX (X = Cl) with I yields a mixture of the biphosphite V and another product believed to be either triethylammonium tris(o-phenylenedioxy) phosphate or spirobenzodioxaphospholane X. Similarly, dioxaphospholane IX (X = NMe2) reacts with I forming a mixture of XI and XII.

On April 30, 1994, Houalla, Douraid; Bounja, Zouhair; Skouta, Said; Wolf, Robert; Jaud, Joel published an article.SDS of cas: 2160-93-2 The title of the article was Macrocycles containing bicyclophosphorane moieties. And the article contained the following:

The first stable macrocycles, e.g. I (R = CMe3, Ph), containing pentacovalent phosphorus have been obtained by an Atherton-Todd reaction between the bis(hydridobicyclophosphoranes) with the corresponding binucleophile HO(CH2)2X(CH2)2OH. The tricyclic monophosphoranes II (X = O, NBu, NCMe3, NPh) as well as the noncyclic derivative III have also been isolated. A pathway that accounts for the formation of all these compounds is proposed. The x-ray crystal study of 2 16-membered rings, I (R = CMe3, Ph), confirms the diequatorial placement of the macrocyclic frame on the trigonal bipyramidal phosphorus which retains the most favorable axial-equatorial-axial annelation of the bicyclic moiety. Comparison of these 2 mol. structures points out the effect of the nature of X on the conformation of the macrocycle. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2

Abdel; Abbasi, Mohamed M. published an article.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was The behavior of N-tert-butyl-2,2′-iminodiethanol towards some trivalent phosphorus compounds. And the article contained the following:

Treating (HOCH2CH2)2NCMe3 (I) with PCl3 or HMPT in C6H6 gave the 2:3 adduct II, which was hydrolyzed by H2O to give the dioxazaphosphocane oxide III (R = H) (IV) and I. Treating IV with o-chloranil gave a crystalline product which in solution gave an equilibrium mixture of V (R = OH) and III (R = OC6Cl4OH-2).

And the article contained the following:

New energy effective solvents are in demand to make global CO2 capture feasible. Phase change solvents seem to be one avenue to reach this goal. This paper presents new exptl. data and modeling results for four amines that have potential as new solvents in blends for post combustion CO2 capture. Both pure component data and data for amine-water solutions, based on ebulliometer measurements, are presented. The data were fitted to an Antoine equation and an NRTL model in two ways: first in a combined fit of both pure component and binary data and then in sep. fits to the individual data sets. The methods were compared and guidelines as to which method to use, based on available data, is provided. Data for 2-(Isopropylamino)ethanol (IPAE), N-tert-Butyldiethanolamine (N-TBDEA), N-Methyl-1,3-diaminopropane (MAPA) and 1,3-diaminopropane (DAP) from the literature were collected and compared with the new data sets. All data and model parameters are given. For all amines, the best fits provided good to excellent representations of the available data.

On April 26, 2021, Rozanska, Xavier; Wimmer, Erich; de Meyer, Frederick published an article.HPLC of Formula: 2160-93-2 The title of the article was Quantitative Kinetic Model of CO2 Absorption in Aqueous Tertiary Amine Solvents. And the article contained the following:

Aqueous tertiary amine solutions are increasingly used in industrial CO2 capture operations because they are more energy-efficient than primary or secondary amines and demonstrate higher CO2 absorption capacity. Yet, tertiary amine solutions have a significant drawback in that they tend to have lower CO2 absorption rates. To identify tertiary amines that absorb CO2 faster, it would be efficacious to have a quant. and predictive model of the rate-controlling processes. Despite numerous attempts to date, this goal has been elusive. The present computational approach achieves this goal by focusing on the reaction of CO2 with OH- forming HCO3-. The performance of the resulting model is demonstrated for a consistent exptl. data set of the absorption rates of CO2 for 24 different aqueous tertiary amine solvents. The key to the new model’s success is the manner in which the free energy barrier for the reaction of CO2 with OH- is evaluated from the differences among the solvation free energies of CO2, OH-, and HCO3-, while the pKa of the amines controls the concentration of OH-. These solvation energies are obtained from mol. dynamics simulations. The exptl. value of the free energy of reaction of CO2 with pure water is combined with information about measured rates of absorption of CO2 in an aqueous amine solvent in order to calibrate the absorption rate model. This model achieves a relative accuracy better than 0.1 kJ mol-1 for the free energies of activation for CO2 absorption in aqueous amine solutions and 0.07 g L-1 min-1 for the absorption rate of CO2. Such high accuracies are necessary to predict the correct exptl. ranking of CO2 absorption rates, thus providing a quant. approach of practical interest. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).HPLC of Formula: 2160-93-2

And the article contained the following:

A series of phosphorus-nitrogen-phosphorus (PNP) ligands of the type R-N(CH2CH2PPh2)2 (R = C(:O)(C6H4OMe-p), tBu, Ph, C6H4OMe-p) have been prepared Their coordination chem. to palladium(II) and palladium(0) complexes was examined using a combination of x-ray crystallog., NMR, and electrochem. techniques.

On January 31, 2001, Zhu, Chun M.; Wang, Liang Y.; Kong, Lin R.; Yang, Xi; Wang, Lian S.; Zheng, Shao J.; Chen, Fei L.; Feng, Man Z.; Huang, Zong published an article.COA of Formula: C8H19NO2 The title of the article was QSPR study of quenching of singlet oxygen by aliphatic amines. And the article contained the following:

From the quenching rates of singlet O by aliphatic amines, a Quant. Structure-Property Relationship (QSPR) prediction equation was developed for 19 aliphatic amines:. Log(kq) = 71.639 + 7.148Ehomo – 0.0146α. N = 19, R = 0.911, SE = 0.892, F = 36.653, P < 0.00001. The quenching rate depends on two factors: the ionization potential and number of substituents and their size. The quenching rates of some substituted quinolines were determined according to B. Monroe's method. 8-Methylaminoquinoline shows greater quenching rate than the traditional quencher 1,4-diazobicyclo-[2.2.2]octane; it can be used as a good antioxidant. The experimental process involved the reaction of 2,2'-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).COA of Formula: C8H19NO2
