Adsorption of hydrogen chloride on microcrystalline silica
… Combustion of the solid propellant produces hydrogen chloride as one of the major products. In this thesis, the hydrogen chloride/silica system was investigated. Silica was chosen as a model compound to represent ground debris transported into the exhaust cloud as a result of convection. The …

The Interactions between Hydrogen Chloride and various Proton Acceptor Molecules in Low Temperature Inert Matrices
… of interaction with the proton donor molecule hydrogen chloride as indicated by the shift in the stretching vibration.<br/><br/>Matrix isolation methods were investigated by pulsed (PMI) and slow-spray-on (SSO) for samples of hydrogen chloride and propenenitrile (acrylonitrile or vinyl …

Partial Pressure of Hydrogen Chloride Above its Solutions in Non-aqueous Solvents. II Nitrobenzene Solutions
… vapor pressure of a volatile acid solute like hydrogen chloride provides a measure of the basicity of the solvent. The importance of basicity in determining the strength of acids in solution has long been discussed by such investigator s as Latimer, Rode bush, Conant, Hall, and others. Rodebush …

Measurement of Pernitric Acid, Hydrogen Chloride, and Sulfur Dioxide during the Intercontinental Chemical Transport Experiment Campaign
This study presents airborne measurements of HO2NO2, HCl and SO2 using chemical ionization mass spectrometry (CIMS) during the Intercontinental Chemical Transport Experiment (INTEX) field campaign, an intensive study to characterize the chemical composition of the troposphere in the eastern United …

The Partial Pressure of Hydrogen Chloride Above its Solutions in Non-Aqueous Solvents, in Monohalobenzene Solutions
… basic solvent and nitrobenzene weakly basic. Hydrogen chloride is very soluble in water and forms an ionized complex with the solvent. However, in nitrobenzene the solubility is low and an unionized complex is formed between acid and solvent. On the other hand dioxane and acetic acid are two …

Predictable Reactive Ion Etching of Gallium-Arsenide and Aluminum - Gallium-Arsenide in Hydrogen-Chloride/argon Radio Frequency Discharges
The reactive ion etch rate of GaAs in HCl/Ar discharges has been studied as a function of RF power, gas mixture, and applied bias. The bias voltage, defined as the difference between the substrate and the time averaged plasma floating potentials, was found to best predict the etch rate. The etch …

The Partial Pressure of Hydrogen Chloride from its Solutions in Non-Aqueous Solvents at 25° C. III. Ethylene Glycol Solutions
The study of the partial pressure of hydrogen chloride from solutions in various non-aqueous solvents has already been started by Schmelzle1 and Westfall. These investigators carried out their work using benzene and nitrobenzene as solvents. Their results show that solutions of hydrogen chloride in …

A space focused ion time of flight mass spectrometer, and spectroscopy of hydrogen chloride, deuterium chloride, and hydrogen sulfide at "hard" x-ray energies
… the molecule involving neutral dissociation of hydrogen was found to be a significant decay channel, thus raising questions of how effectively dissociation competes with Auger decay in the relaxation process. In addition, a space-focused ion time-of-flight mass spectrometer was constructed to be …

The Partial Pressure of Hydrogen Chloride Above its Solutions in BB Dichloroethyl Ether and Anisole and the Calculation of the Heat and Entropy of Solution
Early attempts to explain phenomena associated with some solutions, such as electrical conductance, were handicaped by the overemphasis of the Arrhenius theory as well as by a lack of data concerning non-aqueous solutions. However the Debye-Huckel theory of interionic attraction inspired such …

The Partial Pressure of Hydrogen Chloride from its Solutions in Phenetole, Diphenyl and N-Butyl Phenyl Ethers and the Calculation of the Heat and Entropy of Solution
… direct measurements of the partial pressure of hydrogen chloride from its solutions which correspond with the law of Henry have been made- in the solvents listed in Table I. These are arranged in the order of increasing Henry law constants.

The corrosion of aluminum by hydrochloric acid vapors
… The rate passed through a maximum at a hydrogen chloride partial pressure of 1.77 mm Hg. The decrease in rate above the maximum is due to the formation of a protective aluminum trichloride six hydrate (Al Cl₃ • 6 H₂O) film. Temperature increased the rate of weight gain at all hydrogen …

Model studies of metal-slag reactions in reaction generated foams.
… of water and glycerol and the oxygen by a hydrogen chloride-nitrogen jet. Droplets of amalgam ejected from the bath by the impinging gas jet, reacted with the hydrogen chloride dissolved in the model slag to produce bubbles, thus forming a dynamic foam. To gain more information about the …
