A comparative kinetic study was carried out and formal kinetic equations were derived for the chemical deposition of cadmium sulfide from aqueous solutions containing various cadmium complexes onto a glass-ceramic substrate by thiourea under conditions of spontaneous nucleation and interfacial area control. The morphology of the resultant films were examined, on this basis their nanostructure nature was confirmed, taking into account the data on crystallite size analysis.

We report the synthesis of benzoxazoles using boric acid as catalyst in aqueous media. Synthesis of 2-substituted benzoxazoles derivatives from 2-amino phenol and a variety of aldehydes were developed under mild reaction conditions. The selection and use of water is emphasized as regards methods to minimize environmental impact. On completion of reaction the products were characterized by IR, NMR and Mass Spectra. These methods are more convenient and reactions can be carried out in higher yield.

The boundary conditions of formation of hydroxides are determined by calculation of ion equilibrium with use of thermodynamic constants of metals For system “Pd(NO3)2 – Al2O3 – La2O3 – HAc – H2O". Possibility of decrease in dynamic viscosity of the “Pd(NO3)2 – Al2O3 – La2O3 – HAc – H2O”, suspension having pH = 3 at addition of 1% of an aqueous solution is experimentally shown cation-active surfactant at 1.74 time: with 850.62 to 488.95 mPa•s. The morphology of particles of suspension before and after the addition in it surfactant cation-active Praestol 655 FC is investigated.

The reactions of condensation–dehydration occurring in alkaline aqueous solutions at t = 65–95 0C and рН = 9–11, resulting in synthesis from unorganic molecules the larger organic molecules as polymers and short polipeptides in the process of modeling of primary hydrosphere, were discussed, as well as the possible mechanisms of the deuterium accumulation in form of HDO in hot water. For this aim we performed experiments with hot mineral water and seawater from Bulgaria and water with varying content of deuterium using IR- and DNES-spectroscopy. As model systems were used cactus juice of Echinopsis pachanoi and Mediterranean jellyfish Cotylorhiza tuberculata. It was demonstrated that hot alkaline mineral water with temperature from +65 0C to +95 0C and the pH value from 9 to 11 is more suitable for the origination of life and living matter than other analyzed water samples. In hot mineral waters the local maximums in IR-spectra are more manifested compared to the local maximums obtained in IR-spectra of the same water at a lower temperature. The difference in the local maximums from +20 0C to +95 0C at each +5 0C according to the Student t-criterion makes up p < 0,05.
