The organometallic chemistry of the group VA elements : compounds of arsenic and phosphorus containing arsinic acid, arsonic acid, arsenyl, phophinous acid or phosphinic acid groups
(1969)
(Diethylamino)dichloroarsine and bis(diethylamino)chloroarsine have been investigated as intermediates in syntheses which lead to a variety of arsinic and arsonic acids containing branched alkyl chains and poly(polymethy ...
An NMR investigation of the metal ion and proton catalyzed reactions of some vitamin B-6 Schiff base systems
(1969)
The alpha and beta deuteration of the alpha amino acids valine and alpha aminobutyric acid is easily accomplished by heating D₂O solutions which are 1 M in the amino acid, 0.2 M in pyridoxal, and 0.1 M in aluminum(III) ...
Equilibrium studies of some anion radical solutions by electron spin resonance
(1969)
Ion pairing affects the E.S.R. spectra of cyclooctatetraene (COT) anion radical, influencing the rates and thermodynamic parameters of the line-broadening process and the disproportionation equilibrium, which controls the ...
The synthesis of some organophosphorus compounds and studies of the electron spin resonance spectra of their free radical anions
(1969)
This research describes the preparation of several new organophosphorus compounds. The e.s.r. (electron spin resonance) spectra of the radicals formed by the reaction of these and other organophosphorus compounds with ...
Synthesis of some 1-aminophosphonic acids containing sulfur and heterocyclic rings
(1969)
Three 1-aminoalkylphosphonic acids were synthesized, utilizing the modified Curtius reaction. Two of the amino phosphonic acids synthesized are analogs of naturally occurring 1-aminoalkylcarboxylic acids. The 1-aminoalky ...
Molecular force fields and thermodynamic properties of electronically excited triatomic and tetraatomic molecules
(1967)
Electronically excited molecules play an important role in photochemical reactions. Up to the present time, thermodynamic properties for the molecules in their excited states have not been reported in the literature. During ...
A gas chromatographic investigation of secondary alcohol and ketone utilization by aerobic microorganisms
(1969)
Low molecular weight aliphatic alcohols and ketones represent a major class of synthetic chemicals and find extensive use as commercial solvents. Their occasional appearance in certain types of industrial waste effluents ...
Synthesis of aminophosphonic acids containing carboxyl groups
(1969)
In this research three new aminophosphonic acids containing carboxyl group have been synthesized and characterized. The amino acids are: aminophosphonoacetic acid, 4-amino-phosphonobutyric acid, and 5-amino-5-phosphonopentanonic ...
A study of low molecular weight asphaltic hydrocarbons
(1965)
Hydrocarbon fractions from three road building asphalts were isolated. The first step was precipitation of the asphaltenes with n-pentane. The petrolenes were then treated with sulfuric acid, followed by chromatography of ...
The synthesis and infrared spectra of some group VA chalcogenides
(1969)
The preparation of compounds having the general formula R₃MX, where R is an alkyl group, M is P, As or Sb and X is O, S, Se or Te has been carried put previously. The fundamental stretching frequency, ν[subscript S](M=X), ...
