Photophysical and Photoprototropic Characteristics of 2-Aminobenzothiazole in beta-Cyclodextrin Medium

The formation of stable inclusion complexes between neutral and monocationic species of 2-aminobenzothiazole (2ABT) with beta-CDx is observed with significant enhancement in absorbance and fluorescence intensity. The stoichiometry of the 2ABT and 2ABTH? with beta-CDx is found to be 1:1 at pH?6.8 and 1.1. Their binding constant values for neutral and monocationic species are found to be 1239.3 and 1259.2?M?1, respectively. Lifetime analysis, FT-IR spectral and SEM image analysis strongly supports the formation of the inclusion complex between 2ABT and beta-CDx. Photoprototropic study shows that there is no remarkable difference in the pKa and pKa* in aqueous and beta-CDx media, which is rules out the formation of the inclusion complex with ?NH2 group of 2ABT inside the cavity of beta-CDx i.e., the ?NH2 group of 2ABT is in aqueous environment. Based on stoichiometry, binding constant and acidity constant values, the structure of the 1:1 complex is proposed.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 272-16-2, help many people in the next few years.name: Benzo[d]isothiazole

Vibrational analysis of thiosaccharin and thiosaccharinate anion. A gradient-corrected density functional and experimental study

A gradient-corrected density functional (DFT) study of thiosaccharin molecule and of the corresponding nitranion was carried out using various combinations of exchange and correlation functionals, with a special emphasis on the vibrational analysis of the studied species. The employed DFT methodologies included the B3LYP, mPW1PW91, HCTH and the OLYP combinations of functionals, using the 6-31+G(d,p) basis set for orbital expansion in solving the Kohn-Sham SCF equations. Full geometry optimizations of thiosaccharin molecule and the corresponding nitranion were carried out employing Schlegel’s gradient optimization algorithm. Subsequently, harmonic vibrational analyses were carried out for the minima located on the corresponding molecular/ionic potential energy hypersurfaces. Also, Fourier transform infrared (FT IR) spectra of thiosaccharin and a series of metal thiosaccharinates (those of Na, K, Mg, Mn, Co, Ni, Cu, Zn, Cd, Hg and Pb) were recorded at room and liquid nitrogen boiling temperature. Experimental FT IR vibrational spectra of the studied systems were analyzed in the light of the computed density functional harmonic force fields for free thiosaccharin molecule and its nitranion. The performances of various DFT methodologies employed were compared.

Improvement of Verdejo white wines by contact with oak chips at different winemaking stages

The effect that the addition of wood at different stages of the winemaking process has on the volatile composition and sensory characteristics of Verdejo wines has been studied. Verdejo control wine was made by the traditional winemaking process without oak chips. Oak chips (7 g/L) were added at different stages of the winemaking process: during alcoholic fermentation (OCAF) and in the young wine (OCW). Higher alcohols, ethyl acetate, hexyl acetate, isoamyl acetates and ethyl esters of straight-chain fatty acids were present at higher concentrations in wines that had contact with oak chips during alcoholic fermentation when compared to control wines. The highest concentrations of benzene compounds, oak lactones and furanic compounds were found in both wines in contact with oak chips, particularly in CW samples. Different sensorial profiles were obtained for the wines depending on the stage of the winemaking process at which the chips were added. All wines investigated in this study can provide a viable alternative to traditional Verdejo wines.

Unusual coordination in a silver thionate complex. Synthesis, structural characterization and theoretical calculations of dinuclear and polynuclear silver(I) thiosaccharinates with pyridine and 1,10-phenanthroline

Treatment of Ag6(tsac)6 (tsac = thiosaccharinate anion) with pyridine (py) and 1,10-phenanthroline (o-phen) each affords two novel silver(I)-thiosaccharinate complexes: dinuclear [Ag2(tsac)2py] (1) and polynuclear [Ag(tsac)(o-phen)]n (2). Both crystal structures have been determined by X-ray diffraction and spectroscopic structural analysis (IR and Raman, UV-Vis, 1H and 13C NMR) have also been made for both compounds. Thermal stability analysis (TGA and DTA) of complex 1 are used to confirm the strength of the pyridine coordination to the silver ion. The molecular structure of complex 1 shows some astonishing characteristics. The two silver atoms are in different environments: one of them is surrounded by two S atoms, while the other completes its coordination sphere by three N atoms, two from the thiosaccharinate anions and the third from a pyridine molecule. The short Ag(1)-Ag(2) contact distance, 2.9681(8) A, indicates an interaction between the two silver metal atoms exists. Complex 2 shows a thiosaccharinate molecule bridging two silver atoms through the exocyclic S atom while the o-phenanthroline ligand is coordinated as a bidentate N,N chelate, forming a polynuclear chain. Quantum chemical calculations confirm the argentophilic character of the Ag-Ag interaction in complex 1, and its structure and vibrational assignments were correlated and confirmed theoretically.

Release of volatile organic compounds by oxidative wear of automotive friction materials

Contribution of friction processes to the environmental pollution was proven in several studies, especially with respect to release of particulate emissions containing metals. Not too many researchers pay attention to volatile organic compounds formation during braking, although it is very relevant topic. When organic friction materials are used, the oxidative processes and thermal degradation always accompanies the friction processes during braking. A low-metallic, brake lining formulation was tested using the ISO 26867 friction evaluation standard procedure in an automotive full-scale brake dynamometer. Sampling of non-airborne debris, suspended airborne particles (PM10) and air was performed directly in the environmental chamber. Released volatiles and semi volatile organics were analyzed using GC/MS, Pyr/GC/MS, FTIR and carbon phase analysis. Occurrence of important groups of volatile organic compounds as PAHs and BTEXs with possible adverse effects on living organisms was confirmed.

Collection of ion-trap mass spectre of sulfonylurea pyrolysis products

The pyrograms of 14 sulfonylureas, i.e. herbicides characterized by high biological activity and low application dose are discussed and the mass spectra of over 30 relevant pyrolysis products as obtained with a heated filament pyrolyzer interfaced to a capillary gas chromatograph/ion-trap detector mass spectrometer are presented. Such a data compilation is useful for diagnostic purposes for both intact sulfonylureas and their metabolites after degradation in soil, because metabolites and pyrolysis products are often identical and most of their mass spectra are lacking in commercially available mass spectral libraries. The performance of the ion-trap detector based on the quality of the mass spectra is briefly discussed.

Aroma potential of Albillo wines and effect of skin-contact treatment

Free and glycosidically-bound aroma compounds were analysed in Albillo grape must, skin and wines, and the effects of different skin-contact treatments on aroma composition and wine sensory characteristics were evaluated. Musts and wines contained large amounts of C6 and benzene compounds. Must skin contact, at 18 C for 15 and 23 h, prompted a considerable increase in free and bound varietal compounds. Therefore, this technique, and the use of glycosidases are two methods recommended as a means for enhancing wine aroma. Skin-contact treatment intensified the fresh and fruity properties that were scored positively by wine tasters.
