SO sorption properties of fly ash zeolites.

Turk J Chem 2020 11;44(1):155-167. Epub 2020 Feb 11.

In the presented study, the sulfur dioxide sorption properties of fly ash zeolite X were investigated. Sorption tests were performed on fly ash zeolite samples that were not prepared specially for sorption, in addition to dried samples and samples in the presence of water vapor. The samples saturated with water vapor showed the highest sorption capacity. The sorption capacity of the samples additionally dried prior to the sorption experiment was higher than that of the samples that were not specially prepared for the sorption test. Regeneration tests indicated relatively good regeneration properties. The obtained results were described with the use of Langmuir, Sips, and Dubinin-Astakhov models, with the Dubinin-Astakhov model providing the best fit.

Suzuki-Miyaura cross-coupling reaction catalyzed by Pd/MgLa mixed oxide.

Org Biomol Chem 2005 Dec 10;3(24):4307-9. Epub 2005 Nov 10.

A new, reusable Pd/MgLa mixed oxide catalyst has been applied successfully in the Suzuki-Miyaura carbon-carbon cross-coupling reaction of aryl halides as well as benzylic bromide with boronic acids in ethanol. The catalyst is air stable, can be stored and handled under an ambient atmosphere and after the reaction it can be recovered by simple filtration and reused without significant loss of activity.

Modified Mg : Al hydrotalcite in the synthesis of oxazolidin-2-ones.

Org Biomol Chem 2005 Mar 10;3(6):967-9. Epub 2005 Feb 10.

Department of Organic Chemical Technology, Budapest University of Technology and Economics, H-1521, Budapest, Hungary.

The modified Mg : Al (3 : 1) hydrotalcite has been found to be an efficient catalyst in the conversion of carbamates into oxazolidin-2-ones under mild reaction conditions. A wide variety of oxazolidin-2-ones were obtained with excellent chemical yield.
