The use of quantum chemical methods in corrosion inhibitor studies

Quantum chemical methods are particularly significant in the study of electrochemistry and provide researchers with a relatively quick way of studying the structure and behaviour of corrosion inhibitors. The originality of this review article is based on the fact that it is the first and unique general reference for all those interested in the use of quantum chemical methods in corrosion inhibitor studies. It begins with a concise summary of the most used quantum chemical parameters and methods and then summarizes the results of research articles in corrosion science over the past 20 years.

Long-Range 1H-15N Heteronuclear Shift Correlation

The investigation of long-range 1H-15N heteronuclear shift correlation NMR experiments has gone from its inception in 1995 to a robust area of research with numerous studies now reported annually. The area has been reviewed twice, covering the literature through about mid-2000. The present report covers the period from where this author’s previous review stopped in late-1999 through the present. New long-range heteronuclear shift correlation methods that are applicable to long-range 1H-15N 2D heteronuclear shift correlation are discussed followed by a discussion of the impact of long-range 1H-15N data on Computer-Assisted Structure Elucidation methods and then a review of the applications of these techniques reported in the literature.

2,4-, 2,5- and 2,6-Dimethylpyridines react with anils of aromatic aldehydes in the presence of dimethylformamide and potassium hydroxide to yield the corresponding distyrylpyridines (‘anil synthesis’).Under the same reaction conditions (4-methylstyryl)pyridines are converted to (stilbenylvinyl)pyridines.Similarly, the Schiff’s base derived from pyridine-3-carbaldehyde and chloranile on treatment with methyl- and p-tolyl-substituted aromatic hetericycles gives the corresponding (heteroaryl-styryl)pyridines, whereas with the Schiff’s bases derived from pyridine-2= and -4-carbaldehyde side reactions, such as dimerization followed by disproportionation predominate.

The role of the apical donor in the decomposition of copper(II) benzoate under DOW-phenol conditions

The synthesis and characterization of copper(II) benzoates with the apical donors pyridine, 2-CH3-pyridine, 2,4-(CH3)2-pyridine, 2,6-(CH3)2-pyridine, 2-fluoropyridine, 2-chloropyridine, 2-bromopyridine, 3-bromopyridine, 2,5-dibromopyridine, 3,5-dibromopyridine, and aniline, starting from copper (II) benzoate, is reported. Single-crystal X-ray structures of the products with four apical ligands show the usual paddle-wheel structure of copper(II) carboxylates; in the case of aniline no paddle-wheel dicopper(II) benzoate could be isolated. The products of thermal decomposition of the pure copper(II) compounds were analyzed by HPLC, LC-MS, and GCFID, and the expected DOW-phenol products were found in all cases other than that of aniline. This supports the assumption that a paddle-wheel dicopper(II) benzoate is required for the DOW-phenol reaction. Generally, high orthoselectivities (to phenyl benzoate and phenol; the selectivity increases with increasing basicity) are obtained, in good agreement with earlier findings on the role of the base. Small but significant steric effects are observed in the series of methylated pyridine donors and the monohalogenated pyridine donors used as apical ligands; with the two dibromopyridine donors there are large steric effects and the DOW-phenol reaction is partially suppressed. With halogenated pyridine donors as apical ligands, a Cu[I]-catalyzed process occurs, leading to dehalogenation.

Fractions composition study of the pyrolysis oil obtained from sewage sludge treatment plant

In this work the parameters of Low Temperature Conversion – LTC were applied in a centrifuged sludge from a sewage treatment plant located in Rio de Janeiro, Brazil. Before the conversion, the sludge was dried and analyzed by TGA to observe its behavior with increasing temperature. The chemical composition of the crude pyrolysis oil was analyzed by FTIR, 1H NMR and GC-MS. The results showed that the oil is a mixture of hydrocarbons, oxygenated and nitrogenated compounds. Using a catalytic treatment it was possible to fractionate the oil where the predominant constituents were hydrocarbons showing that the cracking was effective. An important result was the difference between the calorific value of dry sludge (10MJkg-1), the pyrolysis oil (36MJkg-1) and one of the fractions separated by catalytic cracking (40MJkg-1) when compared with commercial diesel (45MJkg-1).

Prediction of energy release hazards using a simplified adiabatic temperature rise

A computationally simple method is outlined to calculate the maximum adiabatic temperature rise for the decomposition of a compound. This method, termed the MART method, is shown to be useful to assess the likelihood of a compound being an energy release hazard. Calculations were made for a number of classes of compounds and the results were analyzed for each class. The method was shown to give relatively clear transitions between compounds not being energy release hazards up to a breakpoint value and being energy release hazards at higher values past the breakpoint value. Peroxides were shown to be a class of compounds that the method works less well on. A predictive rule that could be used regardless of compound class is suggested. The MART method was compared to the more computationally intensive CART method and was found to be quite similar in performance. Also discussed is the potential incorporation of the MART method into the CHETAHTM software.

Buffer gas modifiers effect resolution in ion mobility spectrometry through selective ion-molecule clustering reactions

Ratione: When polar molecules (modifiers) are introduced into the buffer gas of an ion mobility spectrometer, most ion mobilities decrease due to the formation of ion-modifier clusters. Methods: We used ethyl lactate, nitrobenzene, 2-butanol, and tetrahydrofuran-2-carbonitrile as buffer gas modifiers and electrospray ionization ion mobility spectrometry (IMS) coupled to quadrupole mass spectrometry. Ethyl lactate, nitrobenzene, and tetrahydrofuran-2-carbonitrile had not been tested as buffer gas modifiers and 2-butanol had not been used with basic amino acids. RESULTS: The ion mobilities of several diamines (arginine, histidine, lysine, and atenolol) were not affected or only slightly reduced when these modifiers were introduced into the buffer gas (3.4% average reduction in an analyte’s mobility for the three modifiers). Intramolecular bridges caused limited change in the ion mobilities of diamines when modifiers were added to the buffer gas; these bridges hindered the attachment of modifier molecules to the positive charge of ions and delocalized the charge, which deterred clustering. There was also a tendency towards large changes in ion mobility when the mass of the analyte decreased; ethanolamine, the smallest compound tested, had the largest reduction in ion mobility with the introduction of modifiers into the buffer gas (61%). These differences in mobilities, together with the lack of shift in bridge-forming ions, were used to separate ions that overlapped in IMS, such as isoleucine and lysine, and arginine and phenylalanine, and made possible the prediction of separation or not of overlapping ions. CONCLUSIONS: The introduction of modifiers into the buffer gas in IMS can selectively alter the mobilities of analytes to aid in compound identification and/or enable the separation of overlapping analyte peaks.

Pyrolysis of tobacco wastes for bio-oil with aroma compounds

The pyrolysis of tobacco waste, including tobacco leaf (TL) and tobacco stems (TS), using a fluid bed reactor was investigated for the preparation of bio-oil containing aroma compounds or for use as a liquid fuel. The maximum bio-oil yield from TS was 67.47%, and was higher than that from TL. The bio-oil compositions were analyzed by gas chromatography?mass spectrometry (GC?MS) and can be classified into 10 groups, of which heterocyclic compounds and acids are the most abundant substances from both TL and TS. The oil from TL contains more aroma components with a sweet or tobacco flavor responsible for the cigarette sensory taste. Both oils from the pyrolysis of the two tobacco samples have fewer harmful components than tobacco smoke. The effects of the pyrolysis temperature on the bio-oil composition were also investigated. Most aroma components were obtained at a temperature below 350 ?, which would broke into small molecular compounds as the temperature increased because of secondary decomposition.
