AB  - Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For a more detailed study, in this paper, eighteen compounds of monocarbohydrazones (eight known and ten newly synthesized derivatives) were synthesized and characterized using NMR and IR spectroscopy. As carbohydrazones show E/Z isomerization caused by the presence of the imino group, some of the synthesized mCHs are in the form of a mixture of these two isomers. The effects of specific and nonspecific solvent-solute interactions on the UV absorption maxima shifts were evaluated using linear free energy relationships principles, i.e., using Kamlet-Taft's and Catalan's models. For more information about interactions between dissolved substance and the surrounding medium, correlations have been made with Hansen's solubility parameters. The influence of the structure on the spectral behavior of the compounds tested was interpreted using Hammett's equation. Experimentally obtained physicochemical properties of mCHs were compared to and confirmed with computational methods that included TD-DFT calculations and MP2 geometry optimizations. Graphic abstract

AB  - The substituent and solvent effect on intramolecular charge transfer (ICT) in 5-aryli dene-3-methyl-2,4-thiazolidinediones (series 1) and 5-arylidene-3-phenyl-2,4-thiazolidinediones (series 2) was studied by using experimental and theoretical methodology. The effect of specific and non-specific solvent-solute interactions on the UV-vis absorption maxima shifts was evaluated by using the Kamlet-Taft and Catalan solvent parameter sets. Linear free energy relationships (LFERs) have been applied to the UV-vis and C-13 NMR data by using SSP (single substituent parameter) and DSP (dual substituent parameters). Comparative LFER analysis of 10 styrenic series was performed in order to distinguish contribution of structural and electronic substituent effect on extent of p-polarization in a side chain (vinyl) group. Furthermore, the experimental findings were interpreted with the aid of ab initio MP2 and time-dependent density functional (TD-DFT) methods. TD-DFT calculations are performed to quantify the efficiency of intramolecular charge transfer (ICT) allowing us to define the charge-transfer distance (DCT), amount of transferred charge (QCT), and difference of dipole moments between the ground and excited states (mu CT). It was found that both substituents and solvents influence electron density shift, i.e. extent of conjugation, and affect intramolecular charge transfer character in the course of excitation.

AB  - The substituent and solvent effects on solvatochromism in 3-[(4-substituted) phenylamino] isobenzofuran-1(3H)-ones were studied using experimental and theoretical methodologies. The effect of specific and non-specific solvent-solute interactions on the shifts of UV-Vis absorption maxima were evaluated using the Kamlet-Taft and Catalan solvent parameter sets. The experimental results were studied by density functional theory (DT) and time-dependent density functional theory (TD-DFT). The HOMO/LUMO energies (EHOMO/ELUMO) and energy gap (E-gap) values, as well as the mechanism of electronic excitations and the changes in the electron density distribution in both ground and excited states of the investigated molecules were studied by calculation in the gas phase. The electronic excitations were calculated by the TD-DFT method in the solvent methanol. It was found that both substituents and solvents influence the degree of p-electron conjugation of the synthesized molecules and affect the intramolecular charge transfer character.

AB  - Synthesis of high-performance alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET glycolyzates were synthesized by catalytic depolymerization with trimethylolpropane (TMP) and trimethylolethane (TME) and used as replacement of polyhydroxylic component during the ARs synthesis. The obtained glycolyzates and produced ARs were analyzed using FTIR, 1H and 13C NMR spectroscopy and acid, iodine, and hydroxyl value were determined. Rheological properties of the synthesized ARs, as well as, thickness, adhesion, hardness and the gloss values were determined. All synthesized ARs show good adhesion and hardness and the gloss values are greater than 95%. The influence of the addition of vinyl modified nanosilica Aerosil® R380, functionalized with 3-(trimethoxysilyl)propyl methacrylate (TMSPM) and tris(2-methoxyethoxy)(vinyl)silane (TMEVS), on the mechanical and anticorrosive characteristics of the prepared nanocomposite coatings, based on ARs, was investigated.

Nanocomposites, based on unsaturated polyester resins and hexamethyldisilazane modified silica nanoparticles, were prepared with intention to show one of valuable applicative commercialization of UPe resin. In order to determine potential of the possible implementation of developed new technology for UPe production some aspect of techno- economic analysis was analyzed. Economic potential/benefit and process profitability of the presented technology was based on the use of recycled raw input materials, i.e. waste PET, which is one of the most effective ways to save natural resources, protect the environment, and save money. Principles of green economy was incorporated in the results of developed UPe production technology which is related to both environmental protection and profitability achievement with no additional negative impact to environment, i.e. pollution decrease without negative effect of implemented technology.

AB  - The optimized methods for N-alkyl and N,N-dialkyl substituted thioureas synthesis starting from ammonium thiocyanates, waste water constituent from the production of tetramethylthiuram monosulfide (TMTS), and alkyl amine, are presented in this work., Thioureas synthesis was developed in two ways: Method I-reaction of the thiocyanate and alkylamine in the presence of hydrochloric acid; Method II-reaction of the thiocyanate with benzoyl chloride following by amine addition in the first step, and base hydrolysis in the second step. The structure of the synthesized compounds was confirmed by IR, H-1- and C-13-NMR and MS instrumental methods, and purity was determined by high-performance liquid chromatography method. It is shown that the proposed methods offer a high degree of conversion and purity of product, absence of by-products and technological applicability at industrial scale. Considering the importance of the tetramethylthiuram disulfide (TMTD) and TMTS as vulcanization accelerators as well as thiourea as the pharmacologically active compounds, it can be said that application of the optimized methods of thiourea synthesis will provide significant improvement in sustainable development and implementation of eco-friendly production technology. The described environmentally benign process of thioureas synthesis represents a suitable option to existing methods. thioureas, industrial level, thiocyanate.
