Organometallic redox flow batteries using iron triethanolamine and cobalt triethanolamine complexes

Journal of Power Sources, 2020
Abstract Organometallic complexes consisting of iron- and cobalt-triethanolamine ligand (Fe (TEA) and Co(TEA)) are proposed as redox couple of aqueous redox flow battery (ARFB). Fe (TEA) and Co(TEA) are dissolved in sodium hydroxide (NaOH) electrolyte, while their chemical stability and electrochemical reactivity are quantitatively characterized.

Highly soluble Fe(III)-triethanolamine complex relevant for redox flow batteries

Electrochimica Acta, 2019
International audienceFe-triethanolamine is a promising candidate as anolyte for redox flow batteries (RFBs), owning to its low potential, high solubility and low cost. We report here a new dinuclear structure of this complex at solid state when prepared

BIODEGRADATION OF TRIETHANOLAMINE

Environmental Toxicology and Chemistry, 1996
Abstract Triethanolamine production in the United States exceeds 100,000 metric tons per year. Given this magnitude of production and widespread distribution to consumer product, specialty chemical, and agricultural chemical markets, an understanding of the environmental fate and lifetime of this chemical is warranted.

Quantitative determination of triethanolamine in cements

Cement and Concrete Research, 1993
Abstract A new anakysis method for the quantitative determination of triethanolamine (TEA) in the aqueous phase of cements was developed. TEA was converted into the TEA-Fe3+ complex by treating it with 1M NaOH and 10% Fe3+ solutions. This method was based on the determination of the TEA-Fe3+ complex by polarographic techniques. The TEA content in the

Vinylation of triethanolamine

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1965
1. As a result of improvements in the conditions in mass exchange between the liquid and gas phases, the vinylation of triethanolamine can be conducted over a wide range of pressure (from 12 to 2 atm excess pressure) at 180–200° in presence of alkaline catalysts. 2.

Triethanolamine complexes of copper

Inorganica Chimica Acta, 1999
Abstract A simple benchtop synthesis of the deep blue tetrameric compound [Cu{N(CH2CH2O)3H}]4 prepared from CuSO4·5H2O and triethanolamine is presented. The compound has been characterized in three different crystalline modifications which vary due to the presence of different lattice solvents that include THF, Et2O and H2O. The compound dissolves in

Toxicology of Mono-, Di-, and Triethanolamine

1997
The chemistry, biochemistry, toxicity, and industrial use of monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) are reviewed. The dual function groups, amino and hydroxyl, make them useful in cutting fluids and as intermediates in the production of surfactants, soaps, salts, corrosion control inhibitors, and in pharmaceutical and ...

Analysis of concrete for triethanolamine

Cement and Concrete Research, 1976
Abstract This report details a method for the qualitative and quantitative analyses of triethanolamine in cement paste, mortar and concrete. Using the method, triethanolamine and triethanolamine salts introduced into concrete by ad-mixtures have been detected and quantified at specimen ages from a few hours to over two years.
