The urinary excretion of ethylamine has been measured in 200 unrelated healthy volunteers (100 male, 100 female) who maintained their normal diet. The average daily output was 7.82+/-7.03 mg (mean+/-S.D.) (8.01+/-7.40 male; 7.64+/-6.67 female) with a range of values spreading from 0.22 to 35.27 mg.

Methyl radical reactions with ethylamine and deuterated ethylamines
Transactions of the Faraday Society, 1966The rates of hydrogen-abstraction by methyl radicals from the three different sites in ethylamine have been measured by studying three isotopically different ethylamines: CH3CH2NH2, CH3CH2ND2 and CD3CH2NH2. Photolysis of azomethane over the temperature range 110–180°C has been used as the source of methyl radicals, and velocity constants have been ...

Utilization of ethylamine by yeasts
Antonie van Leeuwenhoek, 1962Thirty-two yeast species (162 strains) have been examined for their ability to utilize ethylamine hydrochloride as sole source of nitrogen. The possible taxonomic use of this property is discussed. The utilization of ethylamine was, with one exception, found to coincide with an ability to utilize L(+)-lysine.

The Decomposition of Ethylamine and Diethylhydrazine
The Journal of Chemical Physics, 1936The decomposition of ethylamine has been reinvestigated in the light of criticism of earlier work. The reaction has been shown to occur by a bimolecular no volume change decomposition into symmetrical diethylhydrazine and hydrogen followed by the decomposition of the hydrazine by a chain mechanism which is first order. The mechanism is shown to account

The action of ethylamine on cellulose part I—The acetylation of ethylamine-treated cotton
Polymer, 1962Abstract The hygroscopicity of cotton that has been acetylated in pyridine after it has been treated with ethylamine, washed with water, and solvent-exchanged with pyridine, has been compared with that of cotton acetylated without pretreatment. The results show that the acetylation does not cause decrystallization additional to that due to the ...

Tea as a Source of Urinary Ethylamine
Nature, 1966ETHYLAMINE is a normal constituent of human urine1,2, but it is not found in rat urine. This suggested that urinary ethylamine might be a product of metabolism of a component of food or beverages.

The microwave spectrum of trans-ethylamine
Journal of Molecular Spectroscopy, 1982Abstract The microwave spectrum of normal trans -ethylamine CH 3 CH 2 NH 2 and that of the -NHD and -ND 2 species were measured and assigned. The obtained rotational constants for the ground state of the normal species are (in MHz): A = 31 758.33 ± 0.08, B = 8749.157 ± 0.025, and C = 7798.905 ± 0.025. The fitted dipole moment components are (

The microwave spectrum of gauche-ethylamine
Journal of Molecular Spectroscopy, 1984Abstract The microwave spectrum of the ground state of the normal species of gauche-ethylamine CH3CH2NH2 and that of -NHD, -NDH, as well as -ND2 isotopic species were measured and assigned. The ground state splits into four substates due to two internal large amplitude motions: inversion (s and a) and internal rotation (o and e) about the CN axis ...

Hydrogen formation in the radiolysis of ethylamine
J. Chem. Soc. D, 1970The yield of hydrogen on radiolysis of pure ethylamine at room temperature is 5·5 ± 0·1 and has three precursors: electrons (G= 2·1 ± 0·1), hydrogen atoms (G≃ 0·7), and unscavengeable hydrogen (G⩽ 2·7); the maximum yield of scavengeable electrons is 2·7.
