CHEMICAL PROBLEMS

Abstract Polyvinyl chloride (PVC) is involved in diverse applications that significantly influence our daily lives; it is industrially synthesized in various configurations in order to fulfill the target application. However, PVC is susceptible to photodegradation, yielding toxic byproducts detrimental to both the environment and human health, which diminishing its utility lifespan. Addressing this concern, current […]

Abstract An acid sodium salt of 2-nitro-terephthalic acid was synthesized and its molecular and crystal structures were studied. The crystallographic parameters of the new compound are as follows: the chemical formula – C8H8NNaO8, Cambridge Crystallographic Database Code: 2332574, molecular weight – 269.14, the temperature during measurement of the crystal parameters – 100.0 K, monocrystalline dimension […]

Abstract This study is focused on investigating the atomic dynamics and vibrational properties of thin layers of cadmium selenide with thickness ranging from 200–500 nm. The studies were carried out using Raman spectroscopy at room temperature. Raman spectra were obtained in the frequency range ν = 100-800 cm-1. Two vibration modes were observed within the […]

Abstract The results of a study of the antifungal properties of an imidazoline hexyl bromide complex obtained on the basis of bicyclo[2.2.1]hept-5-ene-2-carboxylic acid and triethylenetetraamine as an additive to cutting fluids are presented. First, imidazoline was obtained by reacting norbornene carboxylic acid with triethylene tetraamine. In the next step, imidazoline was reacted with hexyl bromide […]

Abstract In this approach, a series of new chalcone derivatives bearing baclofen drug were synthesized via Claisen-Schmidt condensation and evaluated in vitro as anticancer and antioxidant agents. The newly synthesized compounds were characterized by FT-IR, 1H-NMR, 13C-NMR spectra, and elemental analysis. All products were screened in vitro against both cell lines HdFn and MCF-7. The […]

Abstract Juniperus communis L. (common juniper) is a widespread plant species in the Western region of Azerbaijan. The dependence of the composition and content of various biologically active substances in juniper on natural climatic conditions was studied. The results of the study of the substances obtained from the extraction of leaves and branches in ethanol […]

Abstract Nickel complexes are effective catalysts for cross-coupling reactions between alkyl Grignard reagents and alkenyl–S and alkenyl–Se compounds. In this study, various organic compounds were prepared. Ethylnyl 2-((5-chloro-8-quinolinol)oxy) acetate compound (designated as A1) was synthesized by ‎adding potassium carbonate to quinoline and ethyl chloroacetate. The second compound 2-((5-chloro-8- quinolinol)oxy) acetohydrazide (A2) were obtained by reacting […]

Abstract 3D-printing has gained popularity in recent years due to the many advantages it offers over the traditional approaches for instance this technology reduces the time a dentist needs to create and fit dentures to just 2–3 sessions. Fumaric, maleic, and adipic acids with the percentage (0.1 wt.%) were added to chitosan solution (2 wt.%) […]
