CHEMICAL PROBLEMS

Abstract The current research aims to evaluate the photocatalytic activity of (TiO2) with various loading ratios (5%-60%) supported on mesoporous aluminosilicate (zeolite type) called Siral, with aluminum content ranging from 20% to 70%, to enhance the performance of degradation of ibuprofen (IBP) as a pharmaceutical pollutant. The batch reactor is furnished with solarium light to […]

Abstract Moringa oleifera leaves have long been used in conventional medicine to treat a variety of ailments, including fever and sore throat. The close relationship between plants and human health has promoted the development of plant-based therapies, such as pharmaceuticals and nutritional supplements, thereby advancing traditional medicine and adding value to agriculture. In the present […]

Abstract. This brief review presents an analysis of data from the past five years on the “green” synthesis and catalytic activity of cobalt and copper nanoferrites, which are characterized by a wide range of applications. Due to their large reserves, availability, and abundance, plants are the best bioagents for the sol-gel synthesis of ferrites, which […]

Abstract: The features of the crystal structure of bis(tert-butylcyclopentadienyltricarbonyl)molybdenum(I)) (tBuСр)2Мo2(СО)6 (1) have been established. Molecule (1), like the molecule of the unsubstituted complex Cp2Mo2(CO)6 (2)(Cp – C5H5), is in the trans-form. Both complexes (1) and (2) are sterically strained. However, the steric strain of molecule (1) is more pronounced, which is due to the steric […]

Abstract The stable metal complexes of transition metals with benzimidazole derivatives lead to improved physicochemical and biological properties of these compounds. The development of antimicrobial agents becomes possible through complex design based on benzimidazole-derived compounds. The research focused on creating and analyzing bis((1H-benzo[d]imidazol-2-yl)methyl)sulfane (L) as a benzimidazole-derived ligand and studying its Mn(II), Co(II), Ni(II), Cu(II), […]

Abstract This study reports the synthesis of a series of oxazepine derivatives via a condensation reaction between amines and various benzaldehyde derivatives, using benzene as the solvent. The resulting intermediates were subsequently reacted with pyridine-5,7-dione anhydride in dry benzene to afford oxazepine derivatives (H1–H6). The synthesized compounds were characterized by Fourier-transform infrared (FT-IR) spectroscopy, proton […]

Abstract: A methodology has been proposed to improve the efficiency of the industrial straight-run gasoline pyrolysis process, in which part of the gasoline deficit is compensated by propane. The procedure consists of two stages. In the first stage, a theoretically substantiated mathematical model of gasoline pyrolysis is applied to determine the operating parameters that maximize […]

Abstract A sequence of 5-phenyl-4H-1,2,4-triazole-3-thiol Schiff base derivatives ([3a], [3b], [3c], and [3d]) has been synthesized. The spectral analyses validated the synthesis of novel 1,2,4-triazole Schiff bases, which were examined using IR, 1H-NMR, 13C-NMR, and mass spectrometry. The results obtained were corroborated by 2D and 3D molecular modeling. Their docking scores vary from -3.472 to […]
