The impact of combinatorial chemistry of small molecules on the drug discovery process is now widely recognized by the scientific community [1]. Solid-phase organic synthesis (SPOS) is a valuable tool for the generation of structurally diverse compounds for combinatorial libraries. In our work dealing with the solid-phase synthesis of biologically interested compounds, we have developed methodo...

The single electron transfer (SET) reactivity of metal alkyls and hydrides is currently receiving growing attention [1-3]. Thus, it has been demonstrated that aluminum species AIX3 (X = R [4], H [5], Cl [6]) can react with reducible carbonyl compounds to form aluminium containing radical complexes [4-6]. Besides carbonyl compounds, certain N-heterocycles can also be used as electron transfer su...

This study investigated the performance of electrocoagulation using iron and aluminum electrodes for removing silica, calcium and magnesium from cooling tower blowdown and reverse osmosis reject waters. Experiments were conducted at both the bench and pilot scales to determine the levels of target species removal as a function of the coagulant dose. At the bench scale, aluminum removed the targ...

The phase composition and structure of stationary nickel-aluminum promoted catalysts have been studied. It is shown that the consists intermetallic compounds NiAl, NiAl3, Ni2Al3. Changes in microscopic alloys are determined. Modern methods for evaluating hydrogenation catalysts, as well analyzing raw materials products catalytic hydrogenation, established. highest performance characteristic who...

Aluminum master alloys with rare earth metals are widely studied by many scientists around the world, but research on production of Al-Er is still limited. The purpose this work to study microstructure parameters aluminum-erbium obtained metallothermic reduction salt mixtures containing erbium oxide or fluoride. structural features were investigated optical and scanning electron microscopy, dep...

Sodium pyrophosphate (pyro-P, Na4P2O7), sodium tripolyphosphate (tripoly-P, Na5P3O10), and sodium hexametaphosphate (meta-P, (NaPO3)6) were selected as the model compounds of condensed phosphate to investigate the adsorption behavior of condensed phosphate on aluminum hydroxide. The adsorption was found to be endothermic and divisible into two stages: (1) fast adsorption within 1 h; and (2) slo...

Arc thermal metal spray coating provides excellent corrosion, erosion and wear resistance to steel substrates. This paper incorporates some results of aluminum coating applied by this method on plain carbon steel. Thereafter, coated panels were exposed to an environment known to form stable corrosion products with aluminum. The coated panels were immersed in Society of Automotive Engineers (SAE...

A facile and efficient approach for the synthesis of a variety of acridines via the tandem coupling/cyclization of substituted 2-bromobenzaldehydes and anilines is described. The reaction can be accomplished with ease in the presence of a catalytic amount of Pd2(dba)3 and diphosphine ligand dppf, providing a broad range of substituted acridines in good to excellent yields (up to 99%). The Lewis...
