We report a chemiresistive sensor approach based on a TTF-TCNQ charge transfer material, which can real-time detect and distinguish the vapors of alkyl amine and aromatic amine species under ambient conditions, based on the dramatic difference in the kinetics of the electric current recovery processes after the exposure of the two amine species.
In this paper, the applicability of immobilized lanthanum (III) triflate on amine grafted graphene oxide [La(OTf)2-amine grafted-GO] as the first multifunctional catalyst is described for the efficient synthesis of α-aminophosphonates by one-pot three-component reaction of carbonyl compounds, substituted anilines and trialkyl phosphites. Various α-aminophosphonates were synthesized in good to h...
Dehydrogenation of cyclic amines by a coordinatively unsaturated Cp*Ir(iii) phosphoramidate complex.
The reaction of a Cp*Ir(iii) phosphoramidate complex with secondary amines gives amine, imine-bound Cp*Ir(iii) hydride complexes resulting from amine dehydrogenation. These well-characterized species could serve as models of relevant intermediates that have been proposed in catalytic amine dehydrogenation using related N,O-chelated Cp*Ir(iii) pyridonate complexes.
Amine-containing compounds including polymers, oligomers and small molecules, without conventional fluorophores, are found to emit strong visible fluorescence after a one-step heat treatment. Furthermore, our results demonstrate for the first time that not only tertiary amine groups but also primary and secondary amine groups can act as fluorescent moieties.
Amine–borane complexes have been extensively studied as hydrogen storage materials. Herein, we report a new amine–borane system featuring reversible dehydrogenation and regeneration at room temperature. In addition to high purity H2, the reaction between ethylenediamine bisborane (EDAB) (ED) leads unique boron–carbon–nitrogen 5-membered rings in product where one boron is tricoordinated by thre...
Abstract: The use of mixed amine system in gas treating processes is increasing today. For natural gas sweetening purposes, mixed amines are typically mixtures of MDEA and DEA or MEA that enhance CO2 removal while retaining desirable characteristics of MDEA such as reduced corrosion problems and low heats of reaction. In this work, a process simulator was used to predict the performance of an I...
When Escherichia coli was grown in a synthetic medium containing salts, amino acids, and glucose in the presence of bacteriostatic concentrations of sulfonamides, an increase in total diasotizable amine was noted (1). This has nolv been found to be due to the production of a new heterocyclic amine, the nature of mhich may ultimately throIv light on the mechanism of sulfonamide bacteriost,asis. ...
The explosion material due to inner pressure have structural instability and this subject special in case of compounds contain nitrate, nitro, di-azo, and azide agents, …,while show in higher temperature than normal media will be greater. thus, the compound is added as a stabilizer to the materials that are capable of reacting with the products of decomposition of the propellant and stable th...
The recently discovered organic cofactor of bovine serum amine oxidase, topa quinone, is an uncommon amino acid residue in the polypeptide backbone (Janes, S. M., Mu, D., Wemmer, D., Smith, A. J., Kaur, S., Maltby, D., Burlingame, A. L., and Klinman, J. P. (1990) Science 248, 981-987). The amine oxidase gene from the yeast Hansenula polymorpha has been cloned and sequenced (Bruinenberg, P. G., ...
The complexation of a tweezers ligand with zinc perchlorate in the absence and presence of amines in methanol solution was explored. L(2)Zn(2)(ClO(4))(4) was a thermodynamic product of the reaction in the absence of an amine. The complex was shown to interact with aliphatic amines resulting in the formation of a Zn-N(amine) bond. If metal-ligand complexation was carried out in the presence of a...
