The reaction of 1-bromo-2-(1-isothiocyanatoalkyl)benzenes, which are easily derived from 2-bromophenyl ketones or (2-bromophenyl)methanamine, with butyllithium generates 1-(1-isothiocyanatoalkyl)-2-lithiobenzenes, which immediately underwent intramolecular cyclization to give rise to the corresp...

In this work, we described a new synthetic route of 3-bromo-1,2-dihydroquinoline derivatives based on the TBAB/Oxone-mediated radical 6-endo-trig ortho-cyclization of 2-alkynylbenzamide. The reaction proceeded smoothly with moderate functional group tolerance and high reaction efficiency. It is ...

Firemaster BP-6 (FM), a mixture of polybrominated biphenyls (PBB), and the congeners 2,2′,4,4′,5,5′-hexabromobiphenyl (2,4,5-HBB), 3,3′,4,4′,5,5′-hexabromobiphenyl (3,4,5-HBB), and 3,3′,4,4′-tetrabromobiphenyl (3,4-TBB) were tested for their ability to induce mutations in mammalian cells...

Solubility, density and the refractive index were determined for saturated solutions of the systems CuSO4 + H2SO4 + (2-propanol + H2O), CuSO4 + H2SO4 + (FeSO4 + H2O) and CuSO4 + CuCl2 + (H2SO4 + H2O). The experimental study was carried out at 298.15 K, and for different mass ratios of 0.04 of 2-...

In this paper we examine the observational basis for Kuiper's (1969) conclusion that the upper cloud layers of Venus are composed of dihydrated ferrous chloride particles. Using new spectrophotometric observations of Venus, we find that there is no strong evidence for the Fe2+ electronic ba...

Tetracycline antibiotics (TCs) are broad-spectrum antibiotics widely used in the prevention and treatment of human and poultry diseases, which can be frequently detected in natural water, soils and sediments. In this study, tetracycline was used as a model pollutant to investigate the performanc...

The present paper deals with the recovery of the Zn(II) and Fe(II)/Fe(III) from the waste chloride solution of steel industry using solvent extraction and precipitation-stripping process for the synthesis of high purity value added products. The extraction of zinc and iron was performed using Cy...

Nowadays, hexavalent chromium and its content in Portland cement is very actual and often discussed topic. The goal of this study was to observe the influence of different ways of addition of ferrous sulphate heptahydrate on the reduction of hexavalent chromium at the hydration of Portland clink...

A porous graphite (PG) is proposed as anode electrocatalyst of microbial fuel cell (MFC), which is synthesized by thermally decomposing ferrous gluconate followed by leaching iron. The physical characterizations from scanning electron microscopy, Brunauer-Emmett-Teller, X-ray diffraction, Raman ...

In this research, effect of cation type of chloride salts on corrosion behaviour of steel was determined by potentiodynamic polarization test in concrete powder electrolyte solution in presence of corrosion inhibitors. Results showed that cation type of chloride salts not only affected compressi...

Mineral scale deposition is a water-associated production threat for oil and gas productions. Scale deposition can lead to pipe throughput reduction and change in facility surface properties. Scale inhibitors are widely used in oilfield operations to control scale deposition. Fe(II) (ferrous) sp...

Mineral ascorbates are the salts of ascorbic acid, and they are formed by bonding of mineral cation to ascorbate anion. Ascorbate salts may better tolerated by the human body than the corresponding weak acidic ascorbic acid. In this work, we depicted the methodology employed to synthesize single...

Irradiation of 7-chloro-2-methylamino-5-phenyl-3H-1,4-benzodiazepine-4-oxide(I, chlordiazepoxido; the active compound of Librium Roche) with UV light provides a mixture of 1-benzoyl-7-chloro-1,2-dmydro-3-methylaminoquinoxalme(III) and 9-chloro-5-methylamino-2-phenyl-4H-benzo[g]-1,3,6-oxadiazocin...

The FT-IR and FT-Raman spectrum of 7-chloro-2-methylamino-5-phenyl-3H-1, 4-benzodiazepine-4-oxide (7CMP4BO) has been recorded in the region 4000–400 and 4000–100 cm−1 respectively. The optimized geometry, Thermodynamic properties, NBO, Molecular Electrostatic Potentials, PES, frequency and int...

Cinnamic acid is a phenolic acid. It has been reported, it has many physiological functions, including antioxidant, antimicrobial and anti-cancer activities. Because of these properties and its low toxicity, cinnamic acid is now widely used in the food and cosmetic industries. It is used as the ...

The aquatic environmental fate of ethylhexyl methoxy cinnamate (EHMC), one of the most used UVB filters worldwide, was studied by assessing its environmental persistence and photoinduced transformations. The role of direct and indirect photolysis was evaluated. Direct photolysis was shown to pla...

Ultraviolet absorption spectra of 2-ethylhexyl p-methoxycinnamate have been recorded in different solvents and calculated using the time dependent density functional theory. The calculations were performed with the aid of B3LYP, PBE1PBE, M06, and PBEPBE functionals and 6-31+G(2d) basis set. The ...

The purpose of this study was to investigate the bioaccumulation and biochemical responses exposed to one of the main organic ultraviolet (UV) pollutants in the environment, ethylhexyl methoxy cinnamate (EHMC), and its main transformation product, either alone or in combination in zebrafish (Dani...

Neutron reflection and adsorption isotherm measurements have been used to study the adsorption behaviour of hexanoic acid onto α-alumina surfaces. Importantly, the pH dependence of the behaviour has been characterised with a pronounced maximum in adsorption identified at a pH of approximately 5...

Xylaria arbuscula was collected from a “Cypress” tree, Cupressus lusitanica. The whole cells of this endophytic fungus were used in screening for microbial bioreduction of aryl acids. Different p-substituted benzoic acids were evaluated. However, only p-bromobenzoic acid, p-chlorobenzoic acid ...
