Abstract This study involves the preparation of various organic compounds. Ethylnyl 2-((5-chloroquinolin- 8-yl)oxy)acetate compound (A1) was synthesized by adding Potassium carbonate to quinoline and ethyl chloroacetate. The 2-((5-Chloroquinolin-8-yl)oxy) acetohydrazide (A2) was prepared by reacting compound (A1) with hydrazide. Complex of (A3) were obtained by reacting equimolar amounts of compound (A2) with the Platinum salt solution […]

Abstract Using the method of gravimetric and electrochemical measurements, the corrosion rate of St3 steel in the water basins of the Takhtakerpi and Shemkirchay hydroelectric power stations has been determined. To establish the expected corrosivity of water, the chemical composition and some physicochemical parameters of the above waters have been determined. As a result of […]

The validity of the compound structures was ‎confirmed using physical and spectroscopic methods such as infrared spectroscopy, and proton ‎nuclear magnetic resonance spectroscopy. […]

Abstract Reaction of nickel with halogenazomercaptophenol (HAMP) {1-(5-fluoro-2-pyridylazo)-2-hydroxy- 4-mercaptophenol, 1-(5-chloro-2-pyridylazo)-2-hydroxy-4-mercaptophenol} in the presence aminophenols (AP): 2-(N,N-dimethylaminomethyl)-4-methylphenol, 2-(N,N-dimethylaminomethyl)-4-ethylphenol studied by the Extraction-Photometric method. A single extraction with chloroform yields 97.1–98.9% nickel (II) in the form of a mixed-ligand complex (MLC). The optimal acidity range, at which the optical density is maximum and constant, is at pHop. […]

Abstract Using fine organic synthesis methods and the latest capabilities of computational chemistry, for the first time, 2-(4-amino-6-phenyl-1,2,5,6-tetrahydro-1,3,5-triazine-2(1H)-ylidene)-malononitrile, which contains a triazine ring and various functional groups in the molecule, was synthesized without the presence of a catalyst through a one-step three-component reaction. Structural analyses were carried out using X-ray and Hirshfeld surface analysis, and […]

Abstract Copper oxide, Cu2O is a highly versatile product that can obtained by different techniques including high/low temperature thermal oxidation, sputtering, chemical oxidation, anodic oxidation, electrodeposition, among others. Until now, the most efficient synthetic processes to obtain Cu2O require relatively expensive equipment; therefore, we have developed a novel method based on simultaneous convergent oxidation-reduction reactions […]

Abstract Thermodynamic properties of CdSb binary compound were determined using an electromotive force measurement (e.m.f.) method with a liquid electrolyte in the ~300-450K temperatures interval. Equilibrium alloys from the CdSb+Sb phase region of the Cd-Sb system was analyzed by means of the e.m.f. measurements. Phase compositions of all samples were controlled using powder X-rays diffraction […]

Abstract This study investigates sweet corrosion mitigation methods focusing on the efficacy of inhibitors. Specifically, it examines the performance of two types of inhibitors: water-soluble and oil-soluble. Utilising a Rotating Cylinder Electrode (RCE) setup, turbulence is induced in saline solutions to assess the impact of inhibitors on the corrosion of carbon steel. Scanning Electron Microscopy […]

Abstract A series of new 2-(2-aryl amino) phenyl acetamide derivatives were synthesized and their chemical structures were identified using spectroscopic techniques (UV-VIS, FTIR, 1HNMR, and MS). Computational studies have been carried out for prediction reactivity and density function theory (DFT) calculations for the acetamide derivatives, as well as the spatial electron distribution of the highest […]
