S 70 Sol-gel synthesis of titanum dioxide by hydrolysis of titanium glycerolates and peroxides [Electronic resource] / V. A. Osipova, G. S. Zakharova, E. Andreikov, Yu. G. Yatluk, I. Puzyrev // Glass Physics and Chemistry. - 2013. - Vol.39, №4. - С. 398-402. - Bibliogr. : p. 402 (11 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): PHOTOCATALYSIS -- SOL-GEL -- TITANIUM DIOXIDE Аннотация: The sol-gel synthesis of titanium dioxide from titanium glycerolate (TG) and titanyl sulfate was studied. The effect of hydrothermal treatment in an autoclave at 130 C and refluxing TG with the peroxo titanium acid gel on the product properties, i.e.; morphology of the nanoparticles and their aggregates, as well as their ability to adsorption and photocatalytic degradation of methylene blue in aqueous solutions was discussed |
C 73 Combination of the Snh/aza-diels–alder reactions as effective synthetic approach to 8-hydroxy(methoxy)-substituted 2-[6-(1-methylindol-3-yl)pyridin-2-yl]quinoline ligands/fluorophores / M. I. Savchuk, D. S. Kopchuk, I. N. Egorov [et al.] // Russian Journal of General Chemistry. - 2021. - Vol. 91, № 5. - P779-784 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): AZA-DIELS–ALDER REACTION -- 1,2,4-TRIAZINES -- 8-METHOXYQUINOLINE -- DEMETHYLATION -- AUTOCLAVE Аннотация: 8-Hydroxy(methoxy)-substituted 2-[6-(1-methylindol-3-yl)pyridin-2-yl]quinoline ligands were synthesized by means of combination of SNH reaction between 8-methoxy-substituted 2-(6-aryl-1,2,4-triazin-3-yl)quinolones and indole and aza-Diels–Alder reaction of the obtained 1,2,4-triazines with 2,5-norbornadiene. The demethylation of quinoline moiety of 1,2,4-triazine precursor during aza-Diels–Alder reaction in autoclave was demonstrated. |
