Abstract:

A fair amount of research has been carried out on the reactions of nitrous acid with aryl hydrazines, with marked differences in mechanism between the reaction of nitrous acid with 2,4-dinitrophenylhydrazine, and the reaction of nitrous acid with alkyl and halogen substituted aryl hydrazines. It was hoped that study of the electrophilic nitrosation of 2-nitrophenylhydrazine would serve as a link between the two sets of results. A large range of electrophilic nitrosating agents are known, and the spectra of two of these; dinitrogen trioxide (N<SUB>2</SUB>O<SUB>3</SUB>) and nitrosyl thiocyanate

Abstract:

The oxidative intercalation of halogen fluorosulfate derivatives such as I(SO₃F) ₃, Br(SO₃F)₃, BrSO₃F, K[I(SO₃F)₄] and K[Br(SO₃F)₄] from solutions in fluorosulfuric acid into graphite (SP-1 and to a lesser extent HOPG) is studied. In addition, the intercalation of solvated cations of the type I₂₊ and NO⁺ is included in this research as well. The results, supported by microanalysis, X-ray powder diffraction data, Raman frequency shifts, Solid state -¹⁹F-NMR spectroscopy and UV-visible optical spectra of the supernatant solutions support three different courses of the intercalation reactions:

Abstract:

A capillary flow gas viscometer has been used to measure the shear viscosities of the hydrofluoroalkanes HFC 134a, HCFC 123, HCFC 124 and the ternary blend MP 39, at pressures up to 0.1 MPa relative to a nitrogen standard. Having applied small correction factors to the measured flow time data, the resultant viscosities are compared to those obtained by other workers (where possible) using alternative techniques. We calculate self diffusion coefficients and hard sphere collision diameters for the molecules within the rigorous Chapman-Enskog kinetic theory of gases, and calculate optimum well de

In this research, the corrosion performance of two austenitic stainless steels, namely 316L and 254SMO, in concentrated acetic acid solutions containing bromide ions has been investigated. In this research, the influence of two different electrochemical surface treatments (electropolishing and nitric acid passivation) on the corrosion behaviour of 316L stainless steel immersed in 15.3M HAc with 18.7mM bromide ions at 900°C was examined. Also, attemptswere made to study the performance of three organic inhibitors in the same conditions. Corrosion rates are assessed both by weight loss, and line

Abstract:

S-Nitrosothiols have been found to undergo nucleophilic attack by the hydroperoxide anion to effect electrophilic nitrosation of the nucleophile. Peroxynitrite anion is formed in almost quantitative yields and the kinetics of the reaction examined, confirming attack through the deprotonated form of hydrogen peroxide. Conversely, under slightly acidic conditions peroxynitrous acid, the neutral form of peroxynitrite, has been shown to nitrosate an excess of thiol in an indirect pathway. Initially two moles of thiol are oxidised to the corresponding disulfide with the concomitant production of ni

Abstract:

Haloacetic acids (HAAs) are a group of disinfection by-products (DBPs) found in drinking water which are regulated in the USA but not yet in the EU. Epidemiology tests have shown that they may have carcinogenic and mutagenic effects on human beings. HAAs are produced during the disinfection process from the use of chlorination and they may persist during water distribution and finally reach the customers’ tap at concentrations of concern. The formation of HAAs arises from the reaction between precursor material – principally natural organic matter (NOM) – and chlorine, and the species and amou
