A Study of Sympathiomimetic Amines, Synthesis of O-Alkylhydroxylamines

Description: Although many sympathomimetic amines have been prepared, the perfect one has not yet been made. Chemists are still attempting to synthesize a selective drug with more prolonged effects and free from side reactions or compensatory vasodilation. With this idea in mind it seemed feasible to prepare a group of O-substituted hydroxylamines.

Quantitative analysis for aromatic amines in aviation fuels by ultraviolet spectrophotometry

Description: From Summary: "A method of quantitative analysis for individual aromatic amines or mixtures of aromatic amines in hydrocarbon fuel blends by spectrophotometric measurement of ultraviolet-light absorption is presented. The effect of the precision of the spectrophotometric measurements, the purity of the aromatic amine, photochemical decomposition of the amine, and the composition of the fuel on the accuracy of the analysis is discussed and the results of tests of the precision of the procedure are given."

Knock-limited power outputs from a CFR engine using internal coolants 2: six aliphatic amines

Description: Report presenting an investigation to determine the knock-limited performance of AN-F-28, Amendment-2, fuel in a DCFR engine when water solutions of the following aliphatic amines were added as internal coolants: monomethylamine, dimethylamine, ethylendiamine, diethylamine, triethylamine, and butylamine. Results regarding the mean effective pressure, indicated specific fuel competition, indicated specific liquid consumption, and knock-limited inlet-air pressure plotted against fuel-air ratio are presented for each fuel and amine combination.

Further Studies of Amines as Extractants for Uranium from Acid Sulfate Solutions

Description: Abstract: "Since the first report on the use of amines as uranium extractants (ORNL-1734) over eighty additional organo-nitrogen compounds have been examined for their ability to extract uranium from aqueous solutions, particularly sulfate solutions, of the types usually encountered in uranium ore processing. As before, the more promising of these (as well as other compounds previously reported) have been examined further with respect to other characteristics essential to practical application, i.e., reagent loss to the aqueous phase, compatibility with practicable diluents, influence of commonly present anions, reagent stability, sufficient selectivity for uranium, adequate phase separation properties, compatibility with practicable stripping methods, etc. The potential cost and availability of the reagents tested, i.e., certain secondary and tertiary amines, have shown even greater promise as practicable extraction agents than many of the promising compounds previously tested. In addition to the work with sulfate liquors, cursory studies have been made of uranium extraction from fluoride and sulfate-fluoride solutions. Extractions of other metals from sulfate liquors, i.e., titanium and thorium, have been briefly examined."

Knock-limited performance of blends of AN-F-28 fuel containing 2 percent aromatic amines 3

Description: Report presenting tests to investigate the effect of 2-percent additions of nine aromatic amines on the knock-limited performance of AN-N-28 (28-R) fuel. The results of the testing of antiknock effectivneess of the 27 aromatic amines obtained to date in the program are also summarized.

Knock-limited performance of blends of AN-F-28 fuel containing 2 percent aromatic amines 2

Description: Report presenting testing to investigate the effects of 2-percent additions of nine aromatic amines on the knock-limited performance of AN-F-28 (28-R) fuel. The p-toluidine and p-tert-butylaniline gave the best overall improvement in the knock-limited power of the fuel.;

The knock-limited performance of fuel blends containing aromatics 2: isopropylbenzene, benzene, and o-xylene

Description: Report presenting knock-limited small-scale-engine tests of isopropyl-benzene, benzene, and o-xylene blended individually in various concentrations with selected base fuels. Data were obtained to determine the blending sensitivity, lead susceptibility, and sensitivity of the blends to inlet-air temperatures. Isopropylbenzene was found to be the most effective overall.

Gasoline-water distribution coefficients of 27 aromatic amines

Description: Report presenting an investigation of the suitability of 27 aromatic amines for overwater storage of their gasoline blends. The program is also meant to determine the antiknock effectiveness and low-temperature solubility in gasoline.

The low-temperature solubility of aniline, the toluidines and some of their N-alkyl derivatives in aviation gasoline

Description: Report presenting testing to determine the solubilities in gasoline at low temperatures of 15 aromatic amines from the NACA exploratory program as antiknock additives. The solubility data is summarized in a table by interpolating or extrapolating experimental results to obtain solubility at -60 degrees Celsius.

Some Amine Derivatives of 1,4-naphthoquinone

Description: It was the aim of this investigation to prepare derivatives of 1,4-naphthoquinone substituted at the 2- and 3- positions with various amino groups. 2,3-Dichloro-1,4-naphthoquinone was selected as the starting material because of the possibility of replacing the chloro groups in direct substitution reactions with amines.

The effect of six aromatic amines on the preignition-limited performance of 28-R aviation fuel in a CFR engine

Description: Report discussing the results of testing on the suitability of six aromatic amines as fuel additives. Antiknock effectiveness, availability, physical properties, and chemical properties for knock tests were explored. The six aromatic amines were xylidines, cumidines, N-methylxylidines, N-methylcumidines, N-methylaniline, and N-methyltoluidine in 28-R aviation fuel.

Suitability of 18 aromatic amines for overwater storage when blended with aviation gasoline

Description: Report discussing testing of aromatic amines as antiknock additives, and more specifically the suitability of overwater storage for these fuel blends. 12 aromatic amines of three different concentrations at two temperatures were measured. The chemical properties of the most promising fuel blends are described in more detail and correlations were noted.

Ultraviolet absorption spectra of aromatic amines in isooctane and in water

Description: Report discusses the results of a study of the ultraviolet absorption spectra in the 3200 A to 2500 A region of 27 aromatic amines in iscoctane and and in water solutions. Factors that affect the absorption spectra of aromatic amines were investigated, and the spectra in the two different solvents were compared. The main variables affecting the absorption are the nature of the solvent, the purity of the aromatic amines, and photochemical decomposition of the aromatic amines.
