Аннотация: The effect of nanosized copper and aluminum oxides, which have a higher sorption capacity than that of bulk samples, on the Hantzsch reaction was studied. The adsorption of starting benzaldehydes and ethyl acetoacetate on the surface of copper and aluminum nanooxides resulted in the activation of these molecules and accelerated the Hantzsch reaction. In addition, considerable activation of ammonia and intermediates (chalcone and enamine) on the surface of aluminum nanooxide facilitated an increase in the rate and selectivity of the process. The experimental results were used to develop a one-pot method for the preparation of nifedipine and nitrendipine

Ключевые слова (''Своб.индексиров.''): magnetic nanoparticles --n-phosphonomethyliminodiacetic acid--doxorubicin--sio2 coating--sorption
Аннотация: Surface modifi cation of magnetic nanoparticles (MNPs) with tetramethylorthosilicate and 3-aminopropyltrimethoxysilane was studied. The use of N-phosphonomethyliminodiacetic acid for the stabilization of the initial MNPs can signifi cantly increase the coating thickness and specifi c surface area of SiO2/APS-modifi ed (APS is 3-aminopropylsilane) MNPs. The possibility of sorption of antitumor drug doxorubicin (DOX) on the synthesized nanoparticles was studied. The degree of sorption of DOX increases with an increase in the specifi c surface area of the particles.

Заглавие : Synthesis and properties of azines functionalized graphene with extremely high adsorptive ability to Eu3+ ions
Место публикации : Flatchem. - 2022. - Vol. 33. - С. 100348
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: In this work, a versatile synthetic protocol for obtaining of new promising carbon materials based on the C–C coupling of graphenide lithium species with azaaromatic compounds (1,10-phenanthroline, phenyl-1,2,5-oxadiazolo[3,4-b]pyrazine) has been suggested. It was shown that more electrophilic oxadiazolopyrazine gave the product with high degree of graphene functionalization and demonstrated non-isomorphic properties. At the same time, phenanthrolinyl graphene has less functionalization degree due to a lower electrophilicity of azine. However, the large size of pores between organic residues in phenanthrolinyl graphene allows adsorbing almost 10% of Eu3+. The mesurment of adsorption isotherm showed an extremely high affinity of phenanthrolinylgraphene to Eu (III) ions in netural or alkaline conditions, and the obtained hybrid material could work at least 5 sorption/desorption cycles. The structures of azine-graphene dyads were verified by complex of modern physicochemical analyses methods (the Raman spectroscopy, FTIR, XPS, SEM, EDS and TGA analyses).
