Chlorotriammineplatinum(II) Ion : Acid Hydrolysis and Isotopic Exchange of Chloride Ligand

Description: Abstract: The acid hydrolysis of [Pt(NH3)3Cl] has been shown to occur to a measurable extent. for this reaction: [APt(NH3)cCl]+ + H2O [chemical equilibrium symbol with rate constant k-1 above and k1 below] [Pt(NH3)c(H2O)]++ + Cl-, the equilibrium quotient was measured at 25 degree C and 35 degree C. At 25 degree C this quotient was 8.4 x 10-5 at [Mu] (ionic strength) = 0 and 25 x 10-5 at [mu] = .318 M. This variation is consistent with the expected changes in activity coefficients.

The Equation of State of Solids at Low Temperature

Description: Technical report describing and evaluating the the three experimental methods for obtaining equation of state data at low temperatures; (1) approximate measurement of the PVT relationship by a piston-displacement technique, (2) the measurement of a heat capacity at constant volume as a function of molar volume and temperature, and (3) direct measurement of the pressure variation of the elastic constants using ultrasonic techniques. X-ray methods also might be applicable.

Gamma Ray Efficiencies for Well Type Scintillation Crystals

Description: From Abstract : "Gamma ray efficiencies for various sized well type NaI(Ti) crystals have been calculated using an IBM 704 digital computer. The adjustable parameters in the program are the gamma ray energy, the heights and diameters of the crystal and the well, the thickness of the well lining, and the positions of the (point) source inside the well. Some typical results are presented in graphical form."

Flame Spectra of Vanadium, Niobium, Rhenium, Titanium and Molybdenum

Description: Abstract Line spectra of vanadium, niobium, titanium, molybdenum and rhenium of sufficient intensity to allow detection at the 1–10 p.p.m. level can be excited in fuel-rich, oxy-acetylene flames. For the strongest lines of tungsten, the sensitivity of detection is 90 p.p.m. Weak lines of zirconium, hafnium, osmium, tantalum and uranium are also observed in these flames. Recordings of the spectra are given along with wavelength tables of the strongest lines.

Cation Exchange in Acetone-Water-Hydrochloric Acid

Description: Abstract: Distribution coefficients have been measured for the partition of metal ions between cation exchange resin and acetone-water-hydrochloric acid solutions. the differences in distribution coefficients of metal ions are greater in acetone-water media than in aqueous media of the same hydrochloric acid concentration. Using distribution coefficient data, conditions for column separations of mixtures can be selected. Column separations of metal ion mixtures can be effected by eluting wit… more

Tricarbalyllic Acid (Propane-1, 2, 3-Tricarboxylic Acid)

Description: From report : "Tricarbalyllic acid (propane-1, 2, 3-tricarboxylic acid) has a structure similar to that of citric acid, except that it lacks the hydroxyl group attached to the middle of the carbon atom. Properties of the rare earth citrates have been used very successfully in the separation of rare earths by ion exchange methods; consequently it was deemed advisable to study the rare-earth compounds which form with the anion if triarbalyllic acid."

The Treatment of a Cesium Ore by Sulfur Chloride and Chlorine

Description: From Abstract : "A Southern Rhodesian cesium ore containing essentially pollucite was chlorinated by a gaseous mixture of sulfur chloride and chlorine at temperatures between 550 and 770°C. The optimum conditions with the fixed bed reactor used in this study were chlorination at 650°C for 4 1/2 hr with an more particle size that passes a 150 mesh sieve."

Reinvestigation of the CC Stretching and CH3 Rocking Assignments In Isopropyl and tert-Butyl Halides

Description: From report: "In a series of paper (1-3) Sheppard has analyzed the vibrational spectra of simple alkyl halides. During the course of an investigation of the spectra of similar alkyl thiocyanates certain anomalies appeared in the assignments of the CC stretching and methyl rocking vibrations in isopropyl and tert.-butyl halides."

The Uranium-Rhenium Alloy System

Description: Abstract The phase diagram of the uranium-rhenium alloy system is presented along with a discussion on transformation kinetics of the uranium solid solutions. The phase diagram is of the double eutectic type with the intermediate phase having the composition URe2. This phase exhibits allotropy at 180°C and melts congruently at 2200°C. URe2 reacts sluggishly with the uranium solid solutions below 750°C to form the peritectoid compound U2Re. Eutectic reactions occur at 1105° and 2105°C at respec… more

Kinetics of the Alkylation and Acylation of Nickel Dipivaloyimethide

Description: Abstract: A study was made of the reactions of nickel dipivaloyimethide with the following reagents: tirphenylmethyl chloride, benzoyl chloride, [rho]-chloro and [rho]-methyl benzoyl chloride. Infrared spectra of the easily hydrolyzed product of tritylation seem to indicate that enol ether, the product of O-alkylation, is formed. the acyl halides reactor to give the triketones. the latter have been characterized by spectra and C, H, analysis. the kinetics of all the reactions studied were … more

Acid-Base Reactions and Kinetics of the Halates in Fused Nitrates

Description: From Abstract : "The mechanism of the reactions of the halates, bromate, chlorate, and iodate, with dichromate in fused alkali nitrates has been shown to involve a fast equilibrium followed by a slow rate determining strip to give oxygen and halogen gases as final products." Experiments outlined serve as insight into the structure of fused salts or fused electrolytes.
